Need to collect, organize, and deliver reliable data? I build production-ready backend systems that automate the entire data lifecycle—from data collection and validation to PostgreSQL databases, ETL pipelines, APIs, and workflow automation. Instead of delivering isolated scripts, I design complete systems that are reliable, maintainable, and built to grow with your business. Whether you're creating an internal platform, integrating third-party APIs, or processing large volumes of data, my goal is to build infrastructure that continues delivering value long after deployment. My work focuses on three areas: Backend Engineering • FastAPI applications • REST APIs • Backend services • Internal tools Data Engineering • ETL pipelines • PostgreSQL databases • Data validation & processing • Data migration • Data architecture Automation & Data Collection • Workflow automation • API integrations • Custom web scraping • Browser automation • Large-scale data extraction Technology Python • FastAPI • PostgreSQL • SQLAlchemy • Docker • Playwright • BeautifulSoup • Selenium • Pandas • Git • Linux I believe good software isn't measured by how quickly it's written, but by how reliable it is six months later. That's why I focus on clean architecture, maintainable code, and solutions designed for long-term use. If you're looking for an engineer who can build reliable backend systems and data infrastructure—not just scripts—I'd be happy to discuss your project.
