Indonesia
I build production-grade AI systems and full-stack platforms — currently working remotely with US-based teams and open to more of the same. Over the last 3+ years, I've shipped systems across fintech, edtech, healthcare, and government sectors — mostly as tech lead or sole architect on fast-moving projects that went from zero to production fast. What I do well: ▸ AI/LLM Engineering — Full RAG pipelines from scratch: semantic chunking, Gemini/OpenAI embeddings, Qdrant vector retrieval, IAM-filtered top-k search, and scanned PDF OCR fallback. I've also built hybrid prediction systems combining Prophet + XGBoost with real-time FinBERT sentiment engines for industrial commodity markets. ▸ Full-Stack Architecture — I own the full picture: Next.js/TypeScript frontends, Node.js/FastAPI backends, PostgreSQL + Redis + Docker + GitHub Actions CI/CD. Recently led a monolith → microservices migration (Flask → Next.js + FastAPI + Express.js) that cut weekly deployments to daily. ▸ Shipping under pressure — Delivered 14 production features across backend, AI service, and frontend in a single 30-hour sprint. That's not a flex — it's just what the team needed that week. Selected work: → Enterprise AI Document Repository (Next.js + FastAPI + Qdrant + MinIO) — AI chat with cited sources across 100% of document types for a Jakarta manufacturing client → Intelligent certificate platform for Singapore edtech: 12-state workflow engine processing 1,000+ monthly requests (SvelteKit + ElysiaJS + PostgreSQL) → SEO campaign platform ranking #1 on Google within weeks of launch (Next.js 14 + Prisma + PostgreSQL) → LMS scaling to 8,300+ active users with drag-and-drop course builder and data viz dashboards Achievements: → Finalist — APICTA 2024 (Asia Pacific ICT Awards, 16 countries) → Silver Medal — Thailand Inventors Day 2023 (469 teams, 57 countries) → Finalist — Bio Farma × MIT Hacking Medicine 2023 → IELTS Academic 7.0 (C1 Proficient) Stack: Next.js · React · TypeScript · Node.js · FastAPI · SvelteKit · PostgreSQL · Redis · Qdrant · Docker · AWS S3 · OpenAI · Gemini If you're building AI-native products or need a full-stack engineer who works async and ships fast — feel free to connect or message directly.
Architected monolithic Flask → Next.js + Express.js + FastAPI microservices migration, cutting deployment time 75% via GitHub Actions CI/CD, enabling daily releases. Built Fortech SuperApp end-to-end — consolidating Predictive Analytics, AI Document Analytics, Customer Loyalty, Data Scraping, and Cross-Feature Chatbot into one platform; extended to enterprise client PT Krakatau Jasa Industri as a production AI Document Repository (Next.js, FastAPI, MySQL, Qdrant, MinIO). Built full RAG pipeline from scratch: semantic chunking, Gemini embeddings, IAM-filtered Qdrant vector retrieval, and scanned PDF OCR fallback — cited AI chat across 100% of document types. Reduced PostgreSQL query time 40% via index optimisation; engineered JWT auth, IAM filters, audit logging, and MinIO object storage (99.9% uptime). Delivered 14 production features in a 30-hour sprint — observability pipeline, cascade deletion, and executive finance dashboard with auto ledger sync. Built HCMS (Next.js, TypeScript, Prisma, MySQL) with ETL migration, cached reverse-geocoding, rate limiting, and SEO. Architected Hybrid AI Commodity Price Prediction (Prophet + XGBoost) with FinBERT Sentiment Engine, WebSocket recalibration, and TradingView Charts — backed by PostgreSQL + TimescaleDB + Redis.
● Spearheaded the end-to-end development of a high-traffic, SEO-optimized campaign platform using Next.js 14, TypeScript, and Prisma with PostgreSQL. ● Achieved a #1 Google search ranking for target keywords through strategic SEO implementation. ● Engineered a secure storage solution for user-uploaded images and receipts by integrating AWS S3. ● Designed and deployed a seamless CI/CD pipeline on a VPS using Git, enabling automated and efficient updates.
