Fullstack Developer

Since December 2023, I’ve been working as a Fullstack Developer at VNTech, where I’ve had the opportunity to build and maintain a multi-tenant CRM platform from backend to frontend.

Some of the technologies and systems I’ve worked with:

🔹 Backend: Python, FastAPI, PostgreSQL
🔹 Frontend: React, TypeScript
🔹 Architecture: Multi-tenant / schema-per-tenant PostgreSQL
🔹 AI: AI Chat Agent/Copilot, OCR pipeline, RAG, pgvector
🔹 Integration: TikTok Ads, Meta Ads, OAuth, campaign synchronization & UTM attribution
🔹 Distributed Processing: Celery, Redis, Temporal
🔹 Authorization: OpenFGA
🔹 Storage: MinIO, presigned URLs, secure document management

During this journey, I’ve worked across different parts of the product lifecycle — from database design and backend APIs to frontend features, third-party integrations, asynchronous processing, AI workflows, and deployment-oriented architecture.

What I value most is not just learning individual technologies, but understanding how they work together to build a reliable product that can serve real business needs.

Looking forward to continuing to grow as a Fullstack / AI Engineer and taking on more challenging engineering problems. 🚀
