About Gergely
Senior software engineer with 25+ years of experience across machine learning, systems, backend, devops and cloud engineering. Creating scalable and maintainable systems.
My background spans the full stack of ML delivery: from training data pipelines and CNN development (Bosch L4+ autonomous driving project) to LLM API infrastructure and GraphQL microservices (Instructure AI Platform), DevOps/cloud engineering, and high-throughput backend systems serving millions of daily requests (refurbed). I've worked in Python, Go, C/C++, Ruby, and TypeScript across Linux-first environments over two decades.
I do my best work when the problem genuinely matters. My preferred domains are AI safety, climate and clean energy technology, health infrastructure, and animal welfare — anywhere engineering effort translates into reduced suffering or better outcomes at scale. I've built optimization algorithms for EV charging fleets, developed web infrastructure for civil liberties organizations, and analyzed data for national food safety systems. I'm drawn to research-oriented organizations and mission-driven product teams where reliability and correctness are taken seriously.
