Luis Carranza, LLC · Software Engineering Studio · Delaware, USA
We design and ship production software — from concept to launch. Real engineering, delivered, that keeps working when the business grows.
Services
Four things, done properly. No body-shop, no rotating cast — the same engineer who scopes your problem is the one who ships it.
Product-grade web apps that hold up under real traffic — not a prototype with a login page.
iOS and Android apps that feel native, because the hard parts are actually native.
LLM features that ship. Agents, retrieval and evaluation — with the guardrails the demo skipped.
Discovery, architecture and delivery discipline. We decide what to build before we build it.
Process
We start from the problem and the constraints — not from the framework we like.
Interface and architecture decided together, in the same room, before a line of code.
Small increments, always shippable. You see progress weekly, not in a big reveal.
We stay after launch. Monitoring, iteration and the boring work that keeps it alive.
Selected work
A short list, on purpose. Every project here is one we designed, built and still stand behind.
Upload a selfie, get photos of yourself in 18 real scenes. No beauty filter — it still looks like you.
The fact graph of your codebase — static analysis that answers with file:line.
Outcome Used to audit real codebases end to end.
Messaging and automation platform with voice agents running in production.
Outcome Voice agents running in production.
Infrastructure and continuous deployment for teams that ship every day.
Outcome Teams ship every day without a release ritual.
FAQ
We start with a short discovery — usually one or two calls — to understand the problem, the constraints and what "done" means. You get a written scope and a weekly rhythm before anything is built.
Fixed scope for defined work, or a weekly rate for ongoing product work. No surprise invoices, and no billing for time we spent learning your domain.
You do. Full IP transfer, your repositories from day one, no proprietary lock-in and no licence you have to keep paying for.
Yes. We embed with in-house teams regularly — leading a workstream, unblocking an architecture decision, or pairing with your engineers.
TypeScript and Go on the backend, React/Astro and React Native on the front, Postgres for data. We pick boring, durable tools and we are honest when yours are the right ones.
Start
A short call is usually enough to know if we are the right fit. No pitch deck, no discovery-fee theatre — just an honest read on your problem.
