I'm Leandro - a full-stack developer, data architect and tech leader from Buenos Aires, Argentina with 20+ years of experience. I design high-impact, end-to-end solutions spanning 120+ TB database estates, real-time streaming pipelines, AI and blockchain.
I'm currently available for freelance work and consulting projects. I believe in transparency - no selling empty promises or magical solutions. Just real-world systems that will be online forever without architectural problems.
Currently serving as Data Engineer at DGUIAF (Ministry of Finance of GCBA), I lead the development of cutting-edge statistical and logistics software for government entities across Argentina. My role involves architecting enterprise-level solutions that handle complex data processing requirements while maintaining the highest standards of security and compliance.
In collaboration with Madero Solutions, I'm spearheading the creation of a transparent tenders platform that revolutionizes government procurement processes. This project leverages Rust APIs and Rust WebSockets to deliver real-time updates, implementing sophisticated vendor pooling algorithms that optimize supplier selection and reduce costs for public institutions.
The platform integrates advanced microservices architecture with cloud infrastructure to ensure scalability and reliability. We're building robust data pipelines that process millions of transactions while maintaining sub-second response times, making government procurement more efficient and transparent than ever before.
Previously, I've collaborated with multinational companies including Pfizer, Walmart, Prosegur, and AXA Assistance, delivering enterprise-level solutions across healthcare, retail, security, and travel industries. These experiences have given me deep insights into diverse business domains and the technical challenges of serving global organizations.
From quick MVPs to platforms that quietly run for years. I turn fuzzy ideas into clear plans, then into software that ships on time and doesn’t wake you at 3 A.M. Clean architecture, honest trade‑offs, and performance that feels fast because it is. No hand‑waving, no magic—just work you can explain to your team without a whiteboard (and with fewer meetings).
Two decades of turning complex problems into elegant solutions. Every number tells a story of innovation, persistence, and real-world impact.

If you need a steady pair of hands—someone who ships, communicates clearly, and won’t oversell—I’m your guy. We’ll choose the right trade‑offs, keep costs predictable, and deliver software your team will be happy to live with.
Let's talkI write guides and share hard‑won lessons that help developers ship reliable software.
I believe good engineering is generous. I publish practical, field‑tested articles—from databases and backend architecture to DevOps and frontend craftsmanship—so teams can avoid the usual traps and ship with confidence. No fluff, no hype: just clear steps, trade‑offs explained, and patterns you can use tomorrow.
