Privately held market intelligence and technology platform headquartered in Bengaluru — the definitive global hub for information, supply chain data, and digital resources in the coffee sector, connecting 200,000+ users across 175+ countries.

Project: CoffeeWeb Platform, CoffeeWeb Admin

• Leading a 9-person frontend engineering team, owning technical direction, architecture, sprint planning, OKRs, task allocation, performance reviews, hiring, and mentoring — while staying roughly 60% hands-on with engineering.
• Architected and evolved two React applications from the ground up — the customer-facing CoffeeWeb platform and the CoffeeWeb Admin Console for managing platform content, news, market information, and operational data.
• Led frontend architecture for a mobile-first PWA spanning 16 product domains — real-time market data, pricing differentials, industry reports, weather, news, community, AI assistance, trade & exchange, and subscriptions — serving 200,000+ users across 175+ countries in English, Hindi, and Kannada via i18next.
• Re-architected an immature frontend codebase — oversized components, duplicated logic, direct API calls from UI, inconsistent state/props patterns, uncontrolled re-renders, and no consistent error handling — into a structured system with clear component boundaries, reusable patterns, state/data-management conventions, defined API boundaries, and production observability.
• Built and maintain the Node.js market-data service behind CoffeeWeb's live-data pipeline — authenticated external-data collection, market-data processing, persistence, currency processing, and downstream event publishing.
• Designed the frontend integration for real-time market experiences, consuming continuously updated data over WebSocket/realtime APIs to power live quotes, market indicators, and charting.
• Built tiered Regular/Gold/Platinum subscription flows with Razorpay, PayPal, and Stripe integrations, trial management, subscription-gated feature access, and Google OAuth login.
• Adopted Supabase (Postgres + realtime subscriptions) and Firebase (Auth, Firestore, push messaging) to power live chat, notifications, and real-time market data feeds across the platform.
• Established the frontend quality and production-reliability foundation — Jest and React Testing Library (~165 test files), ESLint, Prettier, Husky/lint-staged, Sentry error monitoring, and Azure DevOps CI/CD across development, staging, and production.
• Drove frontend performance work across code splitting, lazy loading, dependency optimization, caching, React rendering, API efficiency, WebSocket handling, and Core Web Vitals.

MarTech company helping brands with customer acquisition and retention — products include the headless loyalty infrastructure RewardX, an online ordering system for restaurants and cloud kitchens, and a WhatsApp-delivered e-invoicing solution.

Project: BookMyShow Deals, Peppo PWA (white-label online ordering), Business Console (Merchant/DMS/RewardX), Event food ordering (Lollapalooza India, Backstreet Boys DNA World Tour)

• Frontend Lead for Peppo, owning the frontend for all Peppo products, and Project Owner for three of them — the Peppo PWA, the Business Console, and Arrow (the BookMyShow Deals channel) — owning delivery end to end with QA, and reviewing and merging 500+ merge requests across the PWA and the console.
• Led the frontend engineering team from the ground up to architect, build, and deploy multiple high-traffic consumer web apps and B2B SaaS portals.
• Engineered the mobile-first Peppo PWA food-ordering application — a white-label, multi-brand app where every restaurant brand runs on its own subdomain — ensuring rapid load times, smooth transitions, and reliable transactional steps across menu, cart, saved addresses, Razorpay payments, live order status, and order cancellation, on Next.js with Material UI and styled-components.
• Built location features for ordering: Google Places address autocomplete ranked by distance, map-pin selection that works on Safari, and a GeoIP fallback when the browser denies location access.
• Added background token refresh, Firebase Cloud Messaging push notifications, Heap analytics and Facebook Pixel tracking, and Sentry logging around payment flows.
• Engineered the Event Ordering reservation flow — food-ordering sites for Lollapalooza India 2023 and the Backstreet Boys DNA World Tour (Mumbai and Delhi) that let attendees reserve meals from venue restaurants.
• Developed the consumer-facing BookMyShow (BMS) Deals interface (Arrow) inside the BMS app, integrating secure checkouts and seamless Razorpay payment workflows to handle real-time merchant dynamic discounts — users pick a listed restaurant, pay the bill, and get the discount — with Express and EJS server-rendered screens for paying the bill, payment confirmation and failure, and redemption, made responsive down to 280px-wide screens.
• Architected the core suite of control panels — the Merchant Console for live order processing, the geographically-mapped DMS Console for partner onboarding, and the modular RewardX Console loyalty engine infrastructure.
• Owned the Business Console — a React, TypeScript, GraphQL (Apollo Client), and Ant Design app restaurant owners use to onboard, set up stores, manage catalog and pricing, and accept or reject live orders — and migrated it from react-apollo to Apollo Client.
• Shipped through Docker and Jenkins from GitLab — DigitalOcean for dev and stage, AWS ECS/Fargate for production — with the Business Console deployed on Netlify.
• Introduced ESLint, Prettier, TypeScript linting, and Husky/lint-staged pre-commit hooks to the PWA and the partner (PMS) console.
• Collaborated cross-team with product managers, backend developers, and UI/UX designers to translate complex product logic and specifications into clean, interactive user interfaces.
• Implemented features and UI with Next.js, TypeScript, JavaScript (ES6), and Node.js, fixed bugs, ran peer code reviews, held responsibility over various product boundaries, documented implemented features (including the engineering-handbook page for Arrow), and supported merchants and customers in various technical forums.

On a mission to enable continuous updates through Liquid Software. The world's top brands — including Amazon, Facebook, Google, Netflix, Uber, VMware, and Spotify — are among the 4,500+ companies that depend on JFrog to manage binaries for mission-critical applications.

Project: JFrog Pipelines — UI module in JFrog Platform UI, Pipelines Node.js client

• Joined JFrog Pipelines at inception and helped build its UI from scratch in Vue.js and Vuex — shipped as a module inside JFrog Platform UI, JFrog's unified product console.
• Built the Integrations experience — create, edit, and view flows for 30+ providers (GitHub, GitLab, Bitbucket, AWS, Azure, GCP, Kubernetes, Docker registries, Slack, Jira, webhooks, and more), in both the user and admin consoles.
• Contributed to the Pipelines Node.js client, the typed TypeScript library JFrog Platform UI's middleware uses to talk to the Pipelines microservice — wrote the Integrations, Projects, pipeline-source permissions, Steps, Resource Versions, and Extension Sources modules, each with Jest and nock tests.
• Worked with the team on real-time run monitoring — a Socket.IO connection tied to navigation and a client-side cache of pipeline, run, and step data kept in sync by socket events, so dashboards update live without polling.
• Contributed to the D3-based pipeline graph that visualizes steps, resources, and their dependencies.
• Worked on node pool management (static and dynamic pools on AWS, Azure, GCP, and Kubernetes), plus pipeline source and extension management.
• Worked on the step console log viewer, rendering colored build output for each pipeline step.
• Collaborated across teams on implementation, code reviews, bug fixes, and feature documentation.

Automates CI/CD and DevOps activities with streamlined workflows across teams and tools — available as an on-premises server product, hosted SaaS, and a hybrid offering called Custom Nodes.

Project: Shippable Platform — web app: job dashboards, node pools, subscriptions & billing, admin console

• Involved in building parts of a highly scalable CI/CD platform with 100,000+ Docker containers spun up every month in production.
• Built features across Shippable's main web app — the AngularJS single-page app, served by a Node.js/Express server, that customers use to run and manage their CI/CD — with 320+ commits in a year across job dashboards, node pools, subscriptions and billing, admin tooling, and search.
• Extended the jobs grid view, the live dashboard of CI jobs: a running console timer, per-job environment variables, smarter wrapping of long job names, Ctrl/⌘/Shift-click to open jobs in new tabs, global next/previous search across the single-pane-of-glass (SPOG) view, and custom filters for the jobs, resources, and deletions tables.
• Built a reusable search-bar directive and rolled it out across the subscription, admin, and grid-view pages, replacing several one-off search bars.
• Built node-pool management: add and edit node pools with runtime versions sorted by semantic version, a Workload column linking each node to the job it's running, Re-Initialize for bring-your-own (BYON) nodes, on-demand node status, and live updates over WebSockets in place of a manual refresh button.
• Reworked the subscription pages: a new searchable subscription page with filter criteria, expandable license lists, parallel-job and private-job counts (shown as Unlimited above 5,000), billing-invoice downloads, and a consistent contact form on the billing page.
• Built guided form sections in the dry-run config builder for creating gitRepo resources, deploy jobs, and cluster resources.
• Improved admin tooling — job-status monitoring and run-duration fixes, shared node-pool forms with validation, business analytics, and the accounts admin page — and aggregated job insights (jobs run and queued, durations) for the project dashboard.
• Added a release-notes changelog page, edit and delete actions for assembly lines, and Gerrit support in project and job views, including names that contain “/”.
• Cleaned up JSHint errors across the app's controllers (admin, dashboards, jobs, projects, search, billing), upgraded core server packages (Express, Request, Moment, Grunt), and removed legacy SaaS-login assets.
• Held responsibility over various product boundaries — fixing bugs, documenting implemented features, and supporting customers in various forums — and ran peer code reviews, merging teammates' pull requests; every merge shipped through Shippable's own Assembly Lines, which built the app's Docker image and deployed it to the release-candidate environment.

Global communications and IT services company focused on connecting its customers to the power of the digital world.

Project: E-Commerce, Instalink

• Working as a developer on the E-commerce team, which develops and maintains the CenturyLink e-commerce website.
• Part of the ECOM Agile team, delivering requirements on direct request of the business for the e-commerce shop using the Scrum process.
• Automating and enhancing the quality of user experience by adding additional features based on business requirements.
• Worked on a web application that consumed various web services utilizing Java, JavaScript, and Velocity technologies.
• Also part of development of the Instalink site for CenturyLink prepaid customers with a mobile-first approach utilizing AngularJS and Bootstrap.

Ask AI — portfolio assistant

A live, streaming chat assistant (this site's /ask-ai page) that answers questions about my experience. Grounded using context stuffing — the entire knowledge base (experience, skills, public log entries) is assembled server-side and injected directly into the system prompt on every request, a deliberate choice over RAG since the corpus comfortably fits in the model's context window with no retrieval step needed. Built on the Gemini API, streams tokens to the client over a ReadableStream, enforces per-IP rate limiting, and strips private/draft content server-side before it ever reaches the model.

YourBot — multi-tenant RAG chatbot platform

A multi-tenant SaaS platform for building, configuring, and embedding custom RAG chatbots trained on a business's own documents. I own the application layer end to end — tenant/team management, the Next.js bot-creation and configuration UI, document management, and the integration surface into backend AI services — while the LLM inference and retrieval execution itself is handled by a separate backend AI service this app integrates with.

Venue Management Console

A B2B back-office console for restaurant and venue operators — sales dashboards, restaurant/venue onboarding, an item library with categories, modifiers and sales-tax rules, role-based user management, and table management. Rebuilt the entire frontend from the ground up as a migration off the platform's legacy Angular UI to React, using Material UI and react-admin for the admin interface, React Router for navigation, and Axios with JWT bearer-token auth against a Spring Boot backend.

finSync — multi-profile personal finance tracker

A personal finance PWA for tracking multiple financial identities under one account — banks, credit cards, loans, investments, and recurring bills, each scoped to its own profile. Built as a Next.js App Router PWA on Supabase (Postgres + Auth), with a data model built around per-user "profiles" (personal, professional, family, spouse — up to five) rather than a single flat account, so every bank, credit card, loan, investment, recurring payment, and transaction is scoped to a profile and isolated via Row Level Security policies that join back to the owning user through auth.uid(). Session handling is hand-rolled rather than the standard Supabase SSR helper — access/refresh tokens are set as httpOnly cookies on login and re-attached per request in middleware, which gates every dashboard route. Feature set spans credit card utilization tracking (limit/utilized/available), EMI loan tracking with part-payments and remaining balance, friend-and-family lending with status and repayment schedules, recurring bill reminders, and an investments ledger — with recent work moving bank/card data fetching into Server Actions and adding page-level cache control for fresher dashboard reads.
