David Wang

I am a product-focused Full Stack Engineer with 10+ years building secure, scalable applications across health‑tech, enterprise SaaS, and marketplace platforms. I specialize in rapid prototyping, iterative delivery, and aligning product vision with technical execution.

At Two Chairs I architected and scaled HIPAA‑compliant microservices and care delivery systems used by 20,000+ active patients and 100+ therapists across 22 states, supporting ~1M API calls/month under SOC2 controls. I built group therapy and clinician tools that increased attendance to 89% and doubled therapist efficiency, and I led multi‑region AWS/GCP infrastructure achieving >99.95% uptime. I also implemented CI/CD, observability, and secure access controls that reduced defect rates and met audit requirements.

Earlier at Besomebody I shipped consumer and enterprise products including React Native mobile apps and a training & placement platform that enabled 1,000+ job placements and thousands of users across multiple cities. I developed payment processing, geolocation search, ETL pipelines, and microservices that improved onboarding speed, booking completion, and operational reliability.

I thrive in ambiguous, fast‑paced environments and bring a pragmatic, cross‑functional approach to building measurable product outcomes with modern cloud-native stacks and strong security practices.
