About me
I like shipping things people actually use. Two of my competition platforms went live nationwide and served 500+ participants. That is the kind of work I want more of.
At Genesys Integrated Indonesia I built a complete Point-of-Sale system from PostgreSQL schema to shadcn/ui frontend, structured with Laravel's Repository–Service pattern. I also shipped registration, product, cart and payment-gateway flows on a production e-commerce app built with Next.js and Express.
Beyond CRUD, I put AI to work inside products: Gemini-powered CV rewriting, a semantic search that ranks candidates by skill relevance, and an image-recognition pipeline served through a web UI. I have led a 4-person IT team as coordinator and I am comfortable working with designers and non-technical stakeholders.
- Full-stack ownership
- Design-to-code precision
- AI features in production flows
- Secure, decoupled APIs

What I do
Frontend Engineering
Pixel-accurate slicing from Figma, responsive layouts, component systems with shadcn/ui and Tailwind, and motion with GSAP that stays smooth on real devices.
AI Integration
LLM APIs inside real product flows: Gemini-powered text generation, semantic search that ranks by relevance, and ML models served behind a web interface. Practical AI, not demos.
API Security & Data
Token-based auth, rate limiting, password-reset flows, and decoupled frontend/backend architecture. Plus SQL, dimensional modeling and Power BI when the data needs to talk.
