Work

AI-assisted NHS pre-operative assessment platform: a conversational agent walks patients through a clinical protocol, extracts findings, scores risk, and routes to deterministic GREEN/AMBER/RED triage for nurse review.

• Lead engineer on the NestJS clinical backend (5 apps, 179 Jest specs) and Next.js 16 portal
• Entity extraction with fabrication filter, 9 risk calculators (STOP-BANG, RCRI, ASA, MUST, PRISMA-7, DASI, Epworth), contradiction and safety detection
• Three-tier model routing (lexicon → 3B NLU → 14B brain); TOON prompt encoding cut tokens per turn ~40%
• Voice pipeline (STT → LLM → TTS): streaming TTS cut first-audio latency from 1.1–2.8 s to ~200 ms

AI-powered conversational recommendation platform turning natural-language queries into curated product and location suggestions.

• Lead engineer on the AI system: GPT-4.1-mini tool-calling agent over hybrid Elasticsearch retrieval (BM25 + cosine on OpenAI embeddings, 6,000+ products)
• LangGraph supervisor fallback for web discovery with a PostgreSQL checkpointer; 20 s turn deadline
• LLM-judged evaluation harness (774-turn corpus) and CI gates: test ratchet, conversation-differential replay, daily staging canary
• Co-owned the Celery data-enrichment pipeline (Playwright scraping, Gemini/OpenAI/Claude enrichment)

Financial learning platform with 10,000+ concurrent users, SEBI-compliant eKYC/eSign, and mobile IAP monetization.

• Scalable backend supporting 10K+ concurrent users
• Regulatory workflows: eKYC, eSign, and compliance integrations
• IAP flows across Google Play and Apple ecosystems

Travel and hospitality platform expanded across 19 countries — immersive journeys across South Asia, Africa, Oceania, and the Mediterranean.

• Scalable booking and content modules for multi-region travel operations
• Flawless execution with attention to detail across diverse markets
