About Me

AI Product Manager & End-to-End Builder

Technical product leader who uses AI coding agents to ship products end-to-end — solo. 7+ years spanning healthcare, wearables, and fitness-tech across the US, UK, Belgium, and India. Moves from product vision and PRD through architecture, implementation, and production deployment by directing AI-powered development cycles. Deep technical fluency meets Agile execution and stakeholder alignment.

  • Ships full products solo: PRD → code → deploy via AI agents
  • 3 IoT products launched: concept → regulatory approval → market
  • Directed AI agent dev cycles — firmware, backend, dashboard
  • 40% faster releases via AI-assisted CI/CD automation

Experience

AI Product Manager – Healthcare Technology

OraLens Healthcare · Bengaluru, India
May 2024 – Present
  • Defined product vision, roadmap, and GTM strategy for a cloud-connected medical device platform — 3 iterations from concept to launch.
  • Directed AI coding agents (Claude, Cursor) to build and ship full-stack features end-to-end — firmware, cloud backend, and clinical dashboard — as the sole AI-empowered product builder.
  • Owned and prioritised backlog based on clinical feedback and business objectives; reduced deployment cycles by 40% via AI-assisted CI/CD workflows.
  • Conducted discovery sessions with clinicians; translated findings into PRDs, user stories, and acceptance criteria fed directly into AI agent development cycles.
  • Presented product demos and strategic recommendations to executive and clinical stakeholders, securing continued investment.

Engineering × Product Philosophy

Build the whole thing.
Own the whole stack.

The best products are built by people who can move between the firmware and the feature spec — who understand why the BLE stack latency matters for the UX, and why the clinical workflow constraint changes the data model.
