Senior Fullstack Engineer — Backend-heavy systems, AI integration, automation, and technical consulting.

📍 Plant City, Florida, US  |  ✉️ rogeriopereira.dev@gmail.com

I work on project-based engagements — clear scope, defined start and end, no ongoing retainer. If your project has a beginning, a middle, and an end, that's exactly what I'm looking for.

I don't run a dev shop and I don't compete on hourly rate. I take on a small number of projects where 15+ years of production experience actually moves the needle: systems that need to scale, break down under load, need AI woven in properly (not bolted on), or need someone who's owned an architecture decision and lived with the consequences.

Typical shapes of work:

• Building a fullstack product or feature from spec to production
• Integrating AI into an existing system in a way that's actually reliable
• Automating a manual process that's quietly costing you time or money
• A focused technical review — architecture, scaling risk, security gaps — with a clear plan, not a vague slide deck

• Redesigned a mission-critical email delivery architecture for a US federal contract, cutting operational costs by 92% while improving reliability and security
• Built and maintained systems processing 220k–300k+ transactional messages per day
• Took legacy applications through full modernization into Laravel + Vue + AWS without disrupting production
• Most of my recent client work is under NDA — this is also why my public commit history has gone quiet since 2022: my day-to-day work runs on an internal Git, not GitHub. Happy to walk through the technical detail directly instead

• Fixed scope, fixed price when the deliverable is well-defined
• Time-based for shorter, exploratory, or advisory work
• No long-term maintenance or support contracts — I build it right and hand it off clean
• I keep a full-time role, so I'm selective about what I take on — that's also why what I do take on gets real attention

Vague "need a developer" messages get skipped — projects with a clear problem get a real reply.

Pitches asking me to act as the "US face" for an overseas operation. (Those get reported as spam and deleted automatically).
