Building AI that works in production

I build AI that ships, and I care about the part after the demo. That means agents that finish the task, retrieval you can trace back to a source, and systems that hold up when real users show up.

Over the past 2 years I’ve worked across the AI stack, from data pipelines to multi-agent products: as the sole AI engineer on Bridgette at Bridgenow.ai, the sole backend engineer on MedEQ’s AI medical education platform, and on ML data pipelines at Cyware.

Outside work, I build fast. I’ve won the Vapi Voice AI and Self-Improving Agents hackathons in NYC. I’ve been the only AI engineer on a team more than once, so I’m comfortable owning everything from architecture and evals to APIs and getting it live.

Work Experience

AI Engineer
MedEQ · USA
Apr 2026 – Present
  • Sole backend engineer on MedEQ, an AI-powered continuing medical education platform where clinicians practice against Claude-driven patient simulations; owned architecture across FastAPI, Cloudflare Workers, and Supabase (Postgres + pgvector).
  • Architected a 7-module CME accreditation system (identity & NPI verification, idempotent batch credit engine, typed/spoken reflection workflow, certificates, audit reporting) built to ACCME requirements with an external accreditation partner.
  • Rebuilt the FDA drug-label RAG ingestion pipeline with end-to-end source lineage across all 15 FDA label sections, so every clinical answer is traceable to its regulatory source.
  • Built a data-driven clinical simulation engine with severity-based patient vitals logic and orchestration observability across multi-call LLM flows, making AI behavior auditable for clinical reviewers.
Generative AI Engineer
Bridgenow.ai · USA
Oct 2025 – Apr 2026
  • Sole AI engineer on Bridgette, an agentic assistant for a B2B expert marketplace, replacing a 10+ step workflow (search → filter → invite → negotiate) with a single conversational interface; owned agent architecture, backend APIs, and frontend streaming.
  • Architected a production dual-agent system (companies vs. experts) using Claude and DSPy, with 8 Zod-validated tool schemas powering expert matching, engagement creation, and earnings analysis.
  • Raised end-to-end task success from ~62% to ~84% and cut hallucinated or incomplete responses by ~25% through validation layers and fallbacks, evaluated on 500+ test queries.
  • Reduced average response time from ~1.2s to under 400ms through prompt optimization and query-level caching.
AI Engineer
Cyware · Bengaluru, India
Jan 2023 – Dec 2023
  • Built Python pipelines to parse, normalize, and sanitize raw security logs into structured, high-signal datasets feeding downstream ML anomaly detection models.
  • Integrated frontend threat-intelligence dashboards with backend AI/ML services, resolving 150+ integration issues to deliver model-driven risk scores to SOC analysts in real time.
  • Led the Vue 2 → Vue 3 migration of threat-intelligence dashboards, improving rendering performance of live predictive risk-scoring views by 30%.
  • Improved product stability by 40% through systematic bug resolution in an Agile workflow (Git, Bitbucket, Jira).

Featured Projects

Agentic AI
Guardian — AI Scam Shield for Families
🥈 2nd Place, Best Use of SurrealDB Agent Memory · Daytona HackSprint NYC 2026

An agentic AI system that intercepts scam texts sent to elderly parents, verifies them by calling the real family member, locks money requests behind a second family “key”, and explains the verdict to the parent in Telugu, English or Spanish.

  • Verify by callback: when a text claims to be family, Guardian calls the real relative on their saved number to confirm or deny it.
  • Money second key: money requests stay locked until a second family member approves with a press-and-hold. The AI can never approve money.
  • Safe link opening: suspicious links are opened in a throwaway Daytona sandbox via a cloud browser, analyzed, and destroyed.
  • Multilingual voice calls (Telugu, English, Spanish) with a family safe phrase and a teach-back question.
  • SurrealDB Agent Memory: every verdict is remembered, so repeat scams are caught instantly for any family, with a retrieval trace.
  • Rules-first safety: the LLM only extracts signals; a deterministic rules engine decides, and every warning cites the rule that fired. Live Arize evals on every case.

ClearCare — AI Healthcare Cost Advocate for Seniors
🥉 3rd Place, Best Use of Lightdash · Self-Improving AI Agents Hackathon, NYC 2026 (200+ builders, hosted at Datadog)

A voice-first AI advocate that tells Medicare patients where to go for care and what it will actually cost them out-of-pocket, before they go.

  • Describe symptoms and show an insurance card; ClearCare recommends where to go and estimates real out-of-pocket cost.
  • Uses a governed “source of truth” (Lightdash semantic layer) for insurance and cost data, so prices are never guessed.
  • Self-correcting agent loop (LangGraph): when it finds a data inconsistency, it fixes its own reasoning before answering.
  • Calm, human-like voice interface designed for seniors who struggle with small screens.

Sonus — Voice AI for Pre-Visit Patient Interviews
🏆 Winner · Voice AI Hackathon, NYC 2026 · Built solo in one night

An AI voice agent that interviews hospital patients before their doctor arrives and hands the physician a formatted clinical note before they walk in.

  • Conducts a natural voice interview covering pain, symptoms and emotional state.
  • Converts the conversation into a structured clinical note ready for the physician.
  • Targets the intake layer of the documentation burden: physicians spend more time on paperwork than with patients.
  • Built solo overnight; won the event judged by Eva Zheng, Kevin Koo and Ryan Ratner.
