Software Engineer Intern
Mar 2026 - Aug 2026 ☆ Jakarta, Indonesia
Worked with senior engineer and PM to build an AI-powered PropTech platform end-to-end, from customer discovery and product decisions to engineering (frontend + backend) and deployment (cloud + ci/cd).
∗Developed a Gemini/LangGraph AI assistant for web and WhatsApp; benchmarked agent architectures (intent routing, ReAct) / models (Gemini, Kimi, Mistral, etc.), built vectorless RAG that reduced knowledge-base conversation costs by ≈70%, and developed proprietary self-hosted LangGraph/Fastify AI runtime with observability.
∗Designed Xendit payment and subscription infrastructure with cards, QRIS, trials, recurring billing, webhooks, and concurrency-safe background processing.
∗Drove WhatsApp migration from a third-party BSP to Meta Cloud API, adding native messaging features while saving ≈Rp1.000.000/month in fixed costs.
∗Built the frontend with React and drove the migration from React Router v6 to TanStack Start, redesigning rendering and data fetching around prerendering, client-side rendering, prefetching, query / route caching, and Suspense to reduce runtime infrastructure cost while maintaining page-load performance.
∗Built supporting platform infrastructure including real-time SSE notifications, idempotent/concurrency-safe scheduled/background jobs, Better Auth authentication/authorization, and a location resolver over ≈7,800 Indonesian records with aliases, fuzzy matching, and third-party provider mappings.
∗Built core product features including paginated property CRUD/search, public listings, image management, onboarding, and third-party exports.
∗Stack: React/TanStack Start, NestJS, PostgreSQL/Drizzle, Redis, LangGraph, and TypeScript, cloud deployment and CI/CD with Railway.
