About me
Ricardo Zuluaga's profile
Senior Solutions Architect who ships production systems — agents, platforms, commerce and payments — not demos. Founder of Medellín Web Soluciones.
I'm Ricardo Zuluaga, a Full-Stack Software Architect with 10+ years of experience, focused on code profitability and efficiency.
Through Medellín Web Soluciones I lead real products: Nova (CrewAI orchestration), LEXIA (Legal OS), omnichannel + Woo Colombia, MWS AI (SaaS sales agent), Bold integrator, paid LMS and platforms like Auge Urbano.
Boutique model: few clients, high seniority, real architecture ownership. I speak recruiter language (seniority, stack, domain) and technical-buyer language (trade-offs, HA, observability) — because I'm usually both on the same call.
Applied stack

Now
Medellín Web Soluciones
Boutique consulting + own products (SaaS and custom): 15-min discovery → diagnosis → measurable delivery → optional retainer.
Local-first & Security
AI that runs inside your perimeter when data privacy isn't negotiable — no dependency on a third-party API that can fail or leak.
High availability
Systems designed to stay up: no single point of failure, built to survive scrutiny from a corporate platform team.
Observability
Metrics and traces at every layer. If something breaks, I see it before the client does — and prove it with evidence, not guesswork.
24/7 automation
Agents and containers that absorb repetitive operational work, so your team can focus on what actually moves the needle.
