Rodrigo Cacilhas

I am a high-skilled Autistic person with over 20-year software development experience. Unlike production-focused developers, I specialise in the logical "engine room" of software – building the high-performance, low-latency infrastructure that powers modern applications. I thrive in environments where technical complexity is high, logic is rigorous, and "clean code" is a requirement, not a suggestion.

Core Competency: Translate abstract, high-level logic into efficient, deterministic code.

Cognitive Edge: as an autistic professional, I offer exceptional pattern recognition and a relentless focus on architecture integrity and edge-case resolution.
