# about

Web engineering Full-Stack with a decade of experience

I'm Brahyan Belalcázar, a Full-Stack developer with over 10 years shipping production software across sectors with distinct business models: industrial mining and electricity (Tripro), tax and legal advisory (Restrepo y Londoño), B2B and B2C e-commerce (Siesa Ecommerce), ERP and interactive signage (LogicalSoft), and publishing (Los Tres Editores). Each sector taught me unique architectures, operational constraints, and engineering techniques — enabling me to take complex features to full production functionality. My core stack centers on JavaScript and PHP, mastered at a senior level over the years: from custom WordPress plugin architecture and REST APIs to complete Node.js applications. Today, I combine that track record with AI-assisted engineering to accelerate iteration speed without sacrificing code quality.

I believe in closing the loop: every feature undergoes simulation, implementation, review, and rigorous testing — always under human engineering control. The open-source code I publish (semantic memory cores, P2P mesh protocols, multi-agent orchestration) serves as my laboratory to validate these techniques: iterate fast, verify always, ship to production.
