Summary

Product-minded Lead Engineer with 7+ years owning customer-facing software from ambiguous requirements through architecture, implementation, UAT, and production. Founding engineer on a healthcare platform led from its initial commit to production, pairing deep React and TypeScript work with product ownership and distributed-team leadership. Works in an AI-native engineering model—agentic coding, context engineering, and multi-agent orchestration—to take on larger implementation scopes while architecture, review, and production decisions stay human-owned, with spec-driven development and Playwright-based verification gates holding the line.

Professional experience

Lead Frontend Engineer / UX · Denim Health

November 2023 - Present · Remote, India; Austin-based team

Joined as Senior Software Engineer; lead frontend/UX role since 2025.

  • Built the healthcare resource-management frontend from its initial commit for roughly 200 care coordinators and 300-400 call agents using it weekly. Owned 87 releases, from discovery and PRDs through implementation, UAT, rollout, and production support.
  • Architected the React 19, TypeScript, and Vite frontend with a Chakra UI design system of 58 component families and a 20-module typed API service layer; set shared routing, form, authentication, and state conventions.
  • Reduced critical-workflow API requests from 40+ to approximately 10-12 through redesigned data fetching and client-side orchestration; eliminated over 90% of redundant custom-field requests through caching.
  • Fixed authentication redirect loops and reduced recorded monthly Sentry error volume from 272K to approximately 75K through instrumentation changes, route-aware sampling, and deduplication.
  • Shipped the first three LLM-backed features: daily-alert and office-note classification with agree/disagree feedback, a conversational assistant for market and practice questions, and call deflection. Isolated call deflection in a Chakra v3 micro-frontend connected to a second API gateway within the shared application shell.
  • Built a real-time call widget for patient conversations with movable picture-in-picture across three view modes, inline chart alerts, follow-up reminders, and Athena and Cerner EHR integrations.
  • Designed and owned table and card resource views, unified search, server-driven filter drawers, interfaces for four permission tiers, and timezone-aware office hours, closures, and absences.
  • Designed product analytics across the browser, App Engine, Cloud Logging, BigQuery, and Grafana, using HMAC-pseudonymized IDs, fail-closed allowlisting, and route templating to measure usage ahead of a customer renewal.
  • Established Vitest and Playwright tests, critical E2E gates on every PR, and eight GitHub Actions workflows automating versioned releases and QA, UAT, and production deploys to App Engine.

Software Development Engineer III · CAW Studios

Oct 2022 - Jun 2023 · Hyderabad, India

  • Led Calibrate's React and TypeScript frontend in an Nx monorepo, delivering multi-language coding assessments and proctoring for a platform that attracted 7,000+ users after launch.
  • Mentored 2-3 frontend engineers, shaped feature priorities, and managed sprints and Jira workflows; partnered with designers to deliver production releases.
  • Established Celito's biotech SaaS frontend with React, TypeScript, Fluent UI, and MVC architecture; set up Storybook, Webpack, ESLint, and Prettier, and led code reviews.

Software Engineer · Topica Edtech Group

Nov 2021 - Oct 2022 · Gurugram, India

  • Built IceCap Group's React loan-underwriting application from wireframes; configured CI/CD with Azure Pipelines and deployment to Azure App Service.

User Interface Engineer · XenonStack

Jul 2019 - Jan 2020 · Chandigarh, India
