What I'm looking for

I’m looking for a team where I can build secure, scalable back-end systems and real-time APIs, modernize legacy code, and ship faster using AI-assisted development—while maintaining quality through strong testing, architecture, and DevOps practices.

I’m a Back-end Developer with +2 years of experience building scalable web applications, SaaS/ERP systems, and gamified platforms. I focus on strong architectures, security practices, RESTful APIs, WebSockets for real-time communication, and performance optimization using caching strategies (Redis) and relational/non-relational databases.

In my current role, I automate processes and optimize infrastructure, reducing execution time by 90% and cutting deployment time from 1h to ~20min, while also accelerating deliveries by 75% through AI-Assisted Development and LLM-Assisted Development (Prompt Engineering, AI Pair Programming, and Human-in-the-Loop). I also strengthen reliability with automated testing and refactoring—then apply my DevOps toolkit (CI/CD, Docker, Linux, Nginx) to keep releases fast and dependable.
