Build AI Systems That Actually Ship

Technical Lead · Full-Stack Developer · Automation, AI, and Infrastructure

About

I build automation systems with AI that replace manual work, unblock technical bottlenecks, and help teams ship faster with fewer mistakes.

Portrait of Mariano Fresno

Technical Leader & Maker

I'm a technical lead focused on automation, AI, and cross-domain systems. I like the kind of work where software, infrastructure, hardware, and practical problem-solving all meet.

My Differentiation

AI-First Approach

I use LLM agents where they save real time: debugging, code generation, and analysis

Cross-Domain Systems

I connect AI, backend, IoT, and infrastructure into systems that work as a whole

Measurable Outcomes

I care about concrete results: time saved, fewer errors, and faster delivery

Summary

Mariano Fresno

I like to research and analyze technical matters, develop end-to-end solutions, create the definition of quality-standards and contribute to the technical and product roadmap with innovation. I generate efficient documentation, improve and automate processes, implement and communicate code-review policies, interact with upper-management and make estimates always prioritizing the quality of the deliveries. I interview and select technical personnel with relaxed evaluations and give feedback timely about and to the candidates.
