What I'm looking for

I’m looking to build production software where I can optimize performance, design solid architecture, and strengthen security—especially through mobile + backend systems with offline-first behavior and reliable, scalable delivery.

I’m a Senior Software Developer with over six years of experience building production software, from fintech applications serving 500k+ active users to full-stack systems and developer tools. I enjoy solving complex performance, architecture, and security challenges and finding the right solution for each project.

In my most recent work, I designed and delivered mobile, full-stack, AI, and developer tooling projects for clients and independent products—specializing in React Native, Fastify, PostgreSQL, performance optimization, security, and offline-first architecture. I’ve built systems like predictive user segmentation using K-means, and PerfKit—an RN + Expo performance monitoring SDK capturing startup, UI thread, JS runtime, navigation, and network metrics.

Previously, I owned core mobile banking systems for a fintech serving 100k+ daily users, improving reliability, security, and performance across critical workflows—reducing JS thread stalls by ~52%, cold-start time by ~45%, and API latency by ~40%. I also strengthened fintech-grade security with OAuth2, biometrics, passkeys (WebAuthn), encrypted storage, and secure token lifecycle management, and engineered low-latency on-device OCR pipelines with VisionCamera + JSI.
