Backend-focused full-stack developer building with Python, FastAPI, Next.js, PostgreSQL, and AI-powered web systems.

I’m a self-taught developer based in Brooklyn, NYC. I moved to the US in late 2025 and have been building real full-stack products while working a full-time job. Backend engineering is my home base: service-layer architecture, clean data models, API design, authentication flows, and systems people can actually use.

Right now, I’m going deeper into scalable backend architecture, AI-powered applications, and the path toward AI/ML inference engineering.

A build-in-public platform for developers where the building process becomes part of the portfolio. Developers can post finished projects, track live projects, write progress journals, and show proof of work over time.

I’m focused on becoming a stronger backend engineer first, then moving deeper into AI engineering and ML/inference systems.

Current areas of focus:

• Advanced FastAPI architecture
• Database design and SQLAlchemy patterns
• Authentication and authorization systems
• Dockerized development workflows
• Redis, WebSockets, and background jobs
• AI-powered web apps
• Local inference and RAG pipelines

• Shipping real projects, not just tutorials
• Clean backend architecture
• Practical product thinking
• Building in public
• Learning deeply and documenting the process
• Turning proof of work into opportunity

Building one real project teaches more than watching ten perfect tutorials.
