Zori Y.

I have over 8 years of hands-on experience building web and mobile applications from the ground up. My background goes beyond writing application code. I understand how systems work at the infrastructure level, from Linux configuration and network routing to high-load databases and modern AI integrations. Whether you need to design a clean backend architecture, optimize database queries, set up a secure CI/CD pipeline, or integrate LLMs into an existing product, I can handle the entire scope without needing constant oversight. What I Work With • Full-Stack Web & Mobile: JavaScript, TypeScript, Node.js, NestJS, Express, Python (FastAPI), React, Next.js, Vue, React Native, Laravel. • Databases & Performance: PostgreSQL, MySQL, MongoDB, Redis. Experience with query optimization, caching layers, read replicas, and data sharding. • DevOps, Linux & Networks: Docker, CI/CD, GitHub Actions, AWS, Nginx, Caddy, Linux system administration, DNS, VPNs, WebRTC, FFmpeg media streaming. • Security & Auth: JWT, OAuth2, API rate-limiting, encryption basics, HTTPS/TLS setup. • AI & Automation: OpenAI API, function calling, RAG pipelines, n8n, automated data collection and processing. How I Approach Projects 1. Full-stack ownership: I can look at a problem from the network and database layer all the way to the frontend UI. That means fewer handoffs and faster problem-solving. 2. Pragmatic architecture: I focus on maintainable, well-typed code that is easy to scale later, avoiding over-engineering where a simple solution works better. 3. Clear communication: I explain technical trade-offs in plain terms so we can make the right decisions for your budget and timeline. If you are looking for a reliable engineer to take ownership of a feature or an entire product stack, send me a message and let's discuss your project.
