Delivered features across 3 production projects in under a year — spanning web automation, healthcare SaaS, and supply-chain compliance — working across React.js, Node.js, TypeScript, and Fastify. Optimized a web-automation platform to handle 100+ concurrent requests by integrating a Python ML pipeline into a Node.js cluster — raising success rate to 95%+. Built reusable React components and integrated Stripe, Twilio, and Firebase end-to-end on an 8-module dental-clinic SaaS — cutting average feature-delivery time by 40%. Raised test coverage to 90% on an RSPO-compliant supply-chain platform within an 8–10 person cross-functional team — reducing client-reported bugs from 4–5 per sprint to near-zero. Engineered AI features end-to-end — RAG over pgvector, hand-rolled SSE token streaming, and Zod-validated structured LLM output — shipping grounded assistants with near-zero hallucination on out-of-scope queries.

Promoted to SSE after 2+ years of consistent delivery, independent architectural ownership, and UI/UX initiative on the same production app. Took sole mobile-engineering ownership of a vehicle-aftersales app serving 150+ users across 3–4 service-center locations — digitizing technician workflows and approvals. Integrated FCM push notifications and shipped releases across App Store, Play Store, and Microsoft Intune — owning submission, release, and post-launch issue resolution end-to-end. Drove TDD adoption across the mobile codebase — cutting code duplication from 40% to under 5% and holding SonarQube green quality gates for 5–6 consecutive quarters. Mentored 3 junior engineers over 1 year on code quality, testing, and TDD — raising team output and consistency. Acted as technical point of contact for client requirement-gathering, live demos, and root-cause analysis while contributing Angular web modules.

Built and maintained features across a full React Native codebase from day one as a core engineer on a large-scale cross-platform vehicle-aftersales app. Implemented Microsoft Active Directory authentication and camera-module integration — delivering secure, hardware-level features with zero critical regressions. Drove UI/UX improvements and made independent architectural decisions beyond assigned scope — directly improving production-app consistency and quality. Developed reusable React Native components using modern design patterns — supporting a growing iOS and Android codebase.

About

I like owning a feature from the messy first spec all the way to the part where it's live and not breaking at 2am. For 5+ years I've shipped production apps across healthcare, supply chain, and automotive — usually as the person who takes something ambiguous and turns it into something that works and ships on time. A few things I'm proud of: → Sole mobile engineer on a vehicle aftersales app for 150+ users — shipped across App Store, Play Store & Microsoft Intune → Built and owned an 8-module dental clinic SaaS, integrating Twilio & Firebase end-to-end → Pushed test coverage to 90% — dropped client-reported bugs from 4–5 a sprint to near-zero → Cut codebase duplication from 40% to under 5% through TDD and mentoring 3 junior engineers Lately I've been building Generative-AI products end-to-end — hand-rolled SSE token streaming, RAG over pgvector, and grounded LLM output that actually says "I don't know" instead of making things up. Same instinct as always: ship it, test it, make it reliable. Stack: React · TypeScript · Redux · Node.js · Express · Fastify · PostgreSQL · pgvector · Drizzle · MongoDB · Redis · AWS · Docker · React Native Open to Full Stack, AI, and Mobile Engineering roles where ownership and product quality actually matter. If that's the kind of work you're hiring for, say hi — I'm easy to reach.
