About
I'm a Senior Data Engineer at Telesur, Suriname's national telecom, where I architect data platforms and build internal AI tooling that accelerates how engineering teams work.
My background spans the full stack of data work — from raw SQL transformations at scale to production ETL pipelines to LLM-powered systems that actually get used. I care about building things that are fast, maintainable, and genuinely useful to the people who depend on them.
I've spent the last few years at the convergence of traditional data engineering and applied AI: shipping an internal LLM-based wiki for enterprise knowledge, integrating AI-assisted workflows into production engineering, and building personal projects that stretch what I can do with a weekend and a Go runtime.
Two-time internal award winner. First-principles builder. Based in Suriname, building for anywhere.
