About Me

I build software for scientific teams, laboratories, and biotech startups. My work focuses on designing robust systems for environments where technical complexity, traceability, and reliability are critical. I have a scientific background and experience developing software infrastructure.

Throughout my career, I've worked across frontend, backend, and infrastructure, taking part in both architectural design and the implementation of complete products. My experience includes developing bioinformatics pipelines, evaluating and generating code for generative models at AI startups, and creating proprietary products. Currently, I am building SouthernBio, a company focused on software for scientific research and biotech. I am particularly interested in working on problems related to laboratory workflows, scientific data management, reproducibility and research automation.

I am open to discuss projects related to these fields or simply chat about technology.
