What I'm looking for

I want to build reliable software end-to-end—shipping front-end and back-end features, APIs, and developer tools—while strengthening architecture and CI/CD. I enjoy correctness-focused engineering and collaborating with teams that value quality.

I’m a Software Engineer (since 2019) building both front-end and back-end systems for real workflows. I’ve worked on desktop+web apps that manage code analysis projects with Electron, TypeScript, and React, and I’ve delivered backend capabilities like a coverage report generator in Python and CLI tools in Bash.

I also design and validate systems where correctness matters: I’ve built an electricity pricing forecast API using Python, Flask, and PostgreSQL. Beyond feature development, I’ve architected a custom message-broker (Python + PostgreSQL) and set up CI/CD pipelines with Azure and GitLab to keep releases smooth and maintainable.
