About me
I'm a backend and full-stack developer building real, working systems, not tutorials or demos. My focus is Node.js, Express, and PostgreSQL, across REST APIs, full-scale SaaS applications, and AI agent integrations using Gemini, GPT, and Claude. I've shipped and currently maintain a live multi-tenant SaaS platform in production, along with AI-powered backends built around structured, validated data pipelines, not fragile prompt-and-hope logic. I write clean, maintainable code and communicate clearly throughout. If you need someone who understands the system end to end, let's talk.... Read more

Work experience

Flyrank_AI

Backend Developer Intern

Flyrank AI • Part-time

Jul 2026 - Present • 2 mos

Working as a Backend Developer Intern at FlyRank AI, building real backend systems rather than isolated coursework exercises. Set up Supabase Auth flows with JWT verification across protected routes, containerized a PostgreSQL REST API using Docker and Docker Compose, and built a schema-validated web scraper with retry logic and structured run reports. Also completed the internship's AI fluency track alongside the backend work, and shipped a capstone project connecting the Gemini API to a PostgreSQL-backed image matching system with Zod validation on every response. The role pushed me from basic CRUD thinking into designing systems that hold up under real authentication and deployment constraints.

Syntecxhub

Backend Developer Intern (Virtual)

Syntecxhub • Part-time

Jun 2026 - Jul 2026 • 1 mo

Completed a virtual backend internship at Syntecxhub, building a REST API with Node.js, Express, and MongoDB. Implemented full CRUD operations with Mongoose schema validation, later merged with a separate authentication module to handle signup, login, and session management with password hashing. Also worked on structured error handling and input sanitization across every route, so bad or incomplete requests get caught before they touch the database. This was my first real experience structuring a backend project from the ground up rather than following a guided tutorial.
