Hello, I'm
I help companies modernize legacy .NET systems without a rewrite, using AI-assisted development to deliver faster and safer.
1 week · fixed price. Not sure where to start with your aging .NET system? In one week I review your code and database and give you a clear plan.
Modules, dependencies, integrations and database, in one clear diagram.
Security, unsupported versions, technical debt and SQL performance, each finding with severity and evidence.
Where to go and why, without a big-bang rewrite.
What to migrate first and how, designed to minimize downtime.
Ranges by phase, with the assumptions written down.
I present the report and answer your questions.
From USD 2,000, fixed.
Under NDA, with read-only access. The report is yours to keep, with me or anyone else. If we continue together within 30 days, the audit fee is credited toward the project.
I’ve always been driven by curiosity about technology. From exploring every computer I could get my hands on, to studying Computer Engineering — that curiosity became a career.
After several years working in-house at companies, I realized my true calling was working independently: analyzing problems, proposing solutions, and building software that genuinely helps businesses succeed.
Today I work with clients across industries to modernize legacy systems and deliver custom web applications, robust APIs, scalable databases, and strategic IT consulting. I’m certified by AWS as both a Cloud Practitioner and AI Practitioner, and I use AI-assisted development to deliver faster and with fewer defects.
From in-house engineering to independent consulting — a career built on solving real business problems.

Joined as Web Developer and Webmaster, later expanded into SEO consulting, and ultimately led the company’s systems development team. Grew from building and managing the web presence to architecting the backend platform that powers the tourism wholesale operation.
A selection of websites, backends, and products built for clients across industries.

From modernizing aging systems to building new ones, I cover the full spectrum of software development and consulting.
Move aging .NET systems (WebForms, VB.NET, .NET Framework) to modern platforms step by step, minimizing downtime and risk.
Custom web applications and REST APIs built front to back, with clean, maintainable code and clear documentation.
Schema design, query optimization and data migration for SQL Server, from slow queries to full redesigns.
Architecture reviews and practical advice to find bottlenecks and propose realistic solutions.
Every engagement starts with a clear plan and an estimate.
Small, shippable steps instead of big-bang rewrites.
I use AI tools throughout the process to read legacy code faster, generate tests and ship with fewer defects. I review every change.
Weekly updates, direct access to me, and async-friendly work across time zones.
Practical thoughts on building software, working with clients, and staying ahead in tech.
A developer tries to add a modern NuGet package to a .NET Framework 4.8 project and hits a wall. What "still supported" actually promises, and what it doesn't.
A consumer store has one price tag per item. A B2B portal doesn't — and that single difference is why "just build a webstore" undersells the real job.
A developer assumes a WebForms page can be ported mechanically, until ViewState proves otherwise. What it actually did, and why the UI has to be rebuilt, not converted.
I’m based in Buenos Aires (UTC-3), which overlaps with US business hours, and I work async-friendly, so time zones are rarely a problem.
Short engagements like the Audit are fixed price, paid 50% upfront and 50% on delivery. Larger projects are agreed in a simple contract with clear milestones.
You do. All work and deliverables belong to the client.
I sign an NDA first, work with read-only access, and don’t keep a copy when the Audit ends.
Almost never. Most legacy systems can be modernized in phases while they keep running.
