Presentation

Also Web & Software developer who enjoys coding by turning ideas into reliable.
I've worked on web apps, backend APIs, automation tools using AI and various projects where the goal was simple: build something that works well and is easy to maintain.
I'm comfortable handling both new builds and existing codebase. I often help clients with following.
- Build web app from scratch
- Develop | Fix backend APIs
- Set up database and handle migration
- Integrate with AI like OpenAI, Chatgpt
- Deploy projects on the cloud servers

My skills: Javascript, Node.JS, Nest.JS, Python, Django, Flask, PHP, Laravel, React, Next.js, MySQL, PostgreSQL, MongoDB, Docker, AWS, Git, Twilio, etc.

I try to keep my process straightforward. If you have a project you'd like help with, feel free ping me. I'm always open to discussing details and seeing if we're a good fit to work together!
