About

I'm David Segun — a software engineer based in Lagos, Nigeria, also known as DOS. I spend a lot of my time thinking about products: how they're built and how they feel to use.

I care a lot about technology, but what I care about more is the solution it provides. I like working on things early and the decisions you make actually shape the product.

I work closely with Haze, a startup building something genuinely interesting, a tool that lets you copy a Figma frame, paste it into Haze, and export a native desktop app. No code required. It directly closes the gap between design and shipping.

I'm contracting at Parsewave, building benchmarks and evaluations for frontier AI models — working with terminal bench, GDPval, and multimodal evaluation.

I'm also a part of Fastcrest, an open source org where I stay involved in code, product, and community. We're shipping reflex-vla, a tool that takes trained VLA models and deploys them to edge GPUs with a single command, the kind of infrastructure that makes robotics development a lot less painful.

On the core team at Paza, where we're building the infrastructure for brand-creator collaborations. I've been architecting AI agents for the platform and leading frontend engineering and design from the early product decisions.

I have a computer science background, which gave me the foundation to understand how software works at a deeper level.

I also run SegzWorks, a design studio I started with a creative designer. It's been a space to collab on the intersection of engineering and design

I've also contributed to OlyntheOS, a privacy-first Linux distribution with local AI built in, focused on the user experience
