If you wanted a generic template or a massive, slow-moving agency, you’d be on a different page. I operate at the intersection of high-end web architecture and brutal technical honesty. For nearly two decades, I’ve been stepping in as a fractional CTO / CIO and elite engineer to rescue projects, build rock-solid digital infrastructure, and design scalable systems that don't break under pressure. No hand-holding required, no outsourced communication delays, and absolutely no fluff. Just bulletproof code and strategic execution. You get a senior partner, not just another ticket-taker. Services: Fractional CTO & Tech Strategy - Stop guessing your tech stack. I align your business goals with scalable architecture, map out development roadmaps, and keep you from burning cash on technical debt. High-End Web Application Engineering - From custom enterprise hubs to sleek progressive web apps (PWAs). I build secure, blazing-fast, digital infrastructure that doesn't buckle under heavy user traffic. Legacy Codebase Rescues - Inherited a digital nightmare from a budget agency? I audit, untangle, and stabilize broken codebases, turning technical liabilities back into business assets. Performance & Speed Optimization - No one waits for slow apps to load. I overhaul rendering paths, optimize databases, and strip away the bloat to maximize your conversion rates and SEO. API Design & System Integration - Connecting your disparate software systems seamlessly. I build secure, bulletproof APIs and integrations that ensure your data flows exactly where it needs to. UX/UI Technical Architecture - Bridging the gap between beautiful design and brilliant engineering. I turn complex user flows and high-end, dark-mode aesthetics into pixel-perfect frontend reality. menos -
