About Me

Open to work

Full-stack engineer with a run of roles across e-commerce, EdTech, EV-charging infrastructure, and legal tech, plus a solo-built healthcare app on the side — usually the one who ends up owning a system end to end, architecture through what happens after it ships. Equally comfortable in frontend, backend, and the infrastructure underneath, with a growing pull toward the harder problems inside a product: how it watches itself, secures itself, and recovers when something breaks.
