About

I build revenue-critical web platforms end to end — React/TypeScript on the client, Kotlin/Java and Node.js services behind it — and I automate the parts engineers shouldn't have to do by hand. 5 years shipping production software across travel (Expedia Group), automotive SaaS (Tekion) and edtech/fintech (BYJU'S). Recent work: • Led a platform-wide Vue → React migration as the team's only frontend specialist — set the architecture, ran a phased cutover, coached backend engineers to frontend self-sufficiency, and raised delivery velocity ~40%. • Designed and shipped an MCP (Model Context Protocol) server over our workflow-execution service so engineers can ask in plain language why a run failed and get probable root cause and remediation — cutting ~30 min of triage per investigation across a 10-engineer on-call rotation. • Built a reusable Claude Code skill automating container vulnerability remediation end to end (GitHub Actions build → Wiz scan → dependency bumps until clean), adopted by 10+ platform services and 5+ Flight Centre services. • Cut API latency 78% (1.52s → 337ms) on a hot Kotlin/Spring Boot reporting path with a Redis caching layer. • Removed a $2K/year commercial licence by rebuilding paid-tier editor features on open-source JointJS. • Earlier: owned order and payment validation processing $10M+/month at 99.999% uptime. Toolkit: TypeScript, JavaScript, React, Next.js, Redux, TailwindCSS · Kotlin, Java, Spring Boot, Node.js/Express, GraphQL (BFF), REST · PostgreSQL, MongoDB, Redis, Kafka · Docker, GitHub Actions, Jest, Cypress · MCP server design, LLM-assisted root-cause analysis, agentic coding workflows.

Work experience

SDE-II at Expedia Group, Jun 2024 - Present · 2 yrs 4 mos, Gurugram, Full-stack engineer (React/TypeScript + Kotlin/Java Spring Boot) across Advertising Technology and EGLOM workflow orchestration. ADVERTISING TECHNOLOGY — SPONSORED LISTINGS (Jun 2026 - Present) • Found and fixed an unreported WebKit-only rendering failure in EG's core charting package — an SVG animation that collapsed charts on Safari/iOS while passing every Chromium check — patched at package level so its 50+ consumer teams never hit it. • Introduced Redis caching on two hot Kotlin/Spring Boot reporting APIs: 78% lower latency on the create path (1.52s → 337ms) and 18% on the read path. • Authored the clickstream event spec for a new partner-facing surface (7 events, client- and server-driven), making funnel conversion measurable for the first time. WORKFLOW ORCHESTRATION PLATFORM (EGLOM) (Jun 2024 - Jun 2026) • Pitched and shipped solo an MCP (Model Context Protocol) server over the workflow-execution service: engineers ask in plain language why a run failed and get probable root cause plus remediation. Read-only by design, cleared with senior engineering and the GenAI platform team — cut ~30 min of triage per investigation across a 10-engineer on-call rotation. • Built a reusable Claude Code skill (published to Expedia's internal catalog) automating container vulnerability remediation end to end — GitHub Actions image build from repo context, Wiz CLI scan, dependency bumps until clean — adopted by 10+ EGLOM and 5+ Flight Centre services. • Led the Vue → React migration end to end as the team's only frontend specialist: set architecture, ran a phased cutover, coached backend engineers to frontend self-sufficiency — raising delivery velocity 40%. • Designed an event-driven trigger service (Kotlin/Spring Boot) for automated workflow executions with full audit tracking. • Built the drag-and-drop workflow editor in React and removed its commercial JointJS+ licence ($2K+/year) by migrating to open-source JointJS and rebuilding paid-tier features in-house.

Software Engineer at Tekion Corp, Apr 2023 - May 2024 · 1 yr 2 mos, Bengaluru, • Rebuilt the Finance & Insurance module's UI/UX and accessibility layer, used by thousands of automotive dealerships. • Refactored the Finance & Insurance codebase, improving code structure, cutting technical debt and improving application performance. • Owned end-to-end localisation/internationalisation for different countries and locales, unblocking launches in French (Canada, France) and German (Germany). • Optimised PDF generation and implemented language translation across the module. • Held production on-call for the module, resolving dealership-reported issues and incoming bug reports. • Ran code reviews and implemented best coding practices across the team.

Module Lead at BYJU'S, Mar 2022 - Apr 2023 · 1 yr 2 mos, Gurugram, • Led technical development of the Payment Validation module and its usage in orders, validating $10M+ of payments per month at 99.999% uptime through peak enrollment cycles. • Managed the address module in orders, including the address-validation and serviceability service with real-time lookup across 19,000+ postal codes. • Implemented Redis caching in the order-punching platform, decreasing API timings by 20-30% at minimum and up to 50% in some cases. • Worked across full-stack development: ReactJS, NodeJS, ExpressJS, MongoDB and Postgres. • Built a configuration system enabling no-deploy feature rollouts.

Mentor at Newton School, Feb 2022 - Feb 2023 · 1 yr 1 mo, Remote

Associate Software Engineer at BYJU'S, Jul 2021 - Feb 2022 · 8 mos, Remote, • Created and managed the Wallet module for Orders. • Created and managed the Bonus Points module for Orders. • Implemented pincode search in the address flow for orders, with real-time lookup. • Created a pincode management module covering more than 19,000 pin codes. • Created and managed configs to allow and disable features, enabling no-deploy feature rollouts. • Performer of the Quarter, Jan 2022.
