Hey, I'm Kevnnard

Available

+6 years shipping production software. Software Engineer specialized in TypeScript full-stack — React/Next.js frontends, Node.js/NestJS APIs.

I design and ship full-stack web and mobile products — from API contract to deploy pipeline. I care about the boring fundamentals: typing, testing, observability, and shipping without breaking things.

About me

I'm Kevin Londoño(known in the field as KEVNNARD), a Software Engineer specialized in TypeScript full-stack, with six years shipping production software across web, mobile, and cloud. I work end-to-end in TypeScript — Next.js and React Native on the client, NestJS and Express on the server — backed by PostgreSQL, Supabase, and standard cloud tooling.

My recent work spans e-commerce platforms handling real transaction volume, internal tooling for insurance and logistics operations, and personal SaaS experiments. I'm comfortable owning a feature from API contract to deploy pipeline, and I prioritize the parts that usually get skipped: typing, testing, observability, and CI that you actually trust.

Beyond client work I ship my own products end-to-end through Three Labs and personal SaaS projects — owning the full lifecycle from architecture to launch. That indie grind is where I learned the boring fundamentals: shipping fast, monitoring production, and rebuilding without excuses. I also contribute to open source tooling and explore systems work in Swift and Go when the problem fits.

Most commercial products (Mis Gastos, Three Trackr, and other revenue-generating work) keep their repos private to protect the business — but I'm happy to walk through architecture, share code samples, or arrange a live demo on request.
