Freelancer profile translated to English.
Back to original languageAbout Alexandre
You have a product idea. You need to build it — fast, well, and ready for real users.
Before writing a single line of code, I ask the hard questions: what is the real problem, what is the true scope of the MVP, what do we cut to launch sooner. Most founders lose months building the wrong product. I help you build the right one.
I'm Alex, a backend engineer specializing in MVPs for early-stage startups. I have designed and built systems in production from scratch — microservice architectures, AI integrations, real-time features, mobile apps.
What I deliver: a functional product with a clean architecture, that real users can use, within the agreed timeframe.
Fixed-price projects. Clear milestones. No surprises.
Stack: Spring Boot · PostgreSQL · React · React Native · Kafka · Docker · AWS · Claude API · OpenAI
