I’m a Full Stack Developer who enjoys turning complex business flows into reliable, API-driven systems. I build modern UIs and backend services with a strong emphasis on integration quality, automation, and maintainable architecture.

Most recently, I designed and implemented the backend foundation for an early-stage CRM and Loan Origination System, including a relational PostgreSQL schema (7+ core entities) and lifecycle states across 11 application states. I implemented a state-machine approach for valid transitions and progress tracking, then built FastAPI services with Pydantic validation and robust AWS S3 document uploads (multipart form data, size/MIME enforcement, and consistent error handling).

I also expanded into database-backed frontend authentication using Next.js App Router, Prisma, and NextAuth.js (CredentialsProvider with JWT sessions), including protected dashboard flows and role/organization metadata for authorization logic. I strengthened reliability through automated testing, manual validation, and technical documentation across backend and frontend workflows.

Earlier, I helped build a SaaS admin platform with Vue 3 and Nuxt 3 (reusable components, async API integration, and gated UI behavior) and supported website development with Craft CMS and Twig. I’ve also shipped client and community projects—from MERN + IoT geofencing for real-time alerts to a bilingual Streamlit FAQ chatbot—while staying committed to collaborative, agile engineering.
