senior engineer · asunción, py · utc-3, your working hours
a one-week, fixed-fee audit tells you exactly what's slow, why, and what it's costing you. then i ship the fixes in fixed-scope sprints. i build real-time platforms for north american utilities that serve fortune 500 clients.
how it works
one week inside your react/next app. i measure performance, read the architecture, and map the scaling risks. you get a prioritized report and a video walkthrough. flat fee, known upfront.
we pick the highest-impact items from the audit and i ship them: core web vitals, refactors, scaling bottlenecks. fixed scope, fixed price, deployed to production.
i built real-time platforms for north american utilities with fortune 500 clients. i run nderoga, my own saas, in production. and i wrote canoncss, an open source css framework. i know what breaks at scale because i've broken it.
real estate saas, founder-built. organization-based property management, subscription plans, ai-powered listing enhancements. live in paraguay with 128 active listings.

why a solo engineer
asunción is utc-3, one hour ahead of new york. i'm online while you are. no twelve-hour reply gaps, no offshore team that looks at it tomorrow.
frontend, backend, infrastructure, and the release itself. no account manager relaying your problem to someone you'll never meet.
nderoga, my real-estate platform, is live in paraguay with 128 active listings. when it breaks, i'm the one who fixes it.
before you ask
you wouldn't, on day one. the audit needs read access and nothing more. by the time a sprint is on the table, you've seen a week of my work on your own codebase.
proof of craft
llm agents refactored this entire site from tailwind to canoncss, my open source css framework designed for llms. the brand survived through a 60-line theme file. the full story is on the blog.

i'm an end-to-end product engineer from asunción, paraguay. i build real-time saas for a north american utility company with fortune 500 clients, and i'm the founder of nderoga and the author of canoncss.
i started at twelve, reverse-engineering online games to see how they worked. more than a decade later i still want the whole loop: design, frontend, backend, infra, deploy. tools included. when the tool i needed didn't exist, i wrote it.
