What I'm looking for

I’m looking for a role where I can own full-cycle engineering—architecture to APIs and DevOps—building reliable healthcare/IoT platforms. I want clear ownership, production-focused performance, and teams that move fast with strong collaboration.

I’m a Full Stack Developer with 2+ years shipping production web apps for healthcare and IoT domains. I focus on end-to-end ownership—architecture, APIs, schema, DevOps, and cross-timezone delivery—so products ship reliably and improve continuously.

In my recent work, I built a multi-tenant SaaS excursion management platform serving 8,200+ IoT devices, with hierarchical org scoping across tenant boundaries. I delivered an admin web console and added environment-aware feature flags plus a full audit/activity-log module for complete ops visibility.

I also engineer for measurable performance. I built an Excel report pipeline that cut generation time from 90s to ~10s using GCS signed URLs, and I optimized emergency event logging and alert data to achieve sub-100ms query performance under live load.

On the IoT side, I integrated Web NFC with QR/barcode fallback and reduced pairing time by 80%, eliminating manual data-entry errors in field operations. I’ve collaborated across cross-functional teams and delivered microservices-based real-time emergency coordination, scaling to 5,000+ active users with sub-second WebSocket-based GPS tracking.
