Whatever the engagement, the shape is the same: a principal-level architect who reads your problem before prescribing, still writes production code himself, and answers for the outcome. 100% remote, in English or Spanish, for clients primarily in North America and Europe.
Five fronts built over 35 years. Most real engagements combine two or three — the point of a 360° profile is that you don't need a different consultant for each layer. And every one of them is hands-on: when the engagement calls for it, I implement the full cycle personally, from architecture to shipped code.
RAG, agentic systems and enterprise data platforms — Dataiku, MS Fabric, Snowflake, Databricks, Azure OpenAI — architected and shipped to production, not to a slide deck. Built and led a 25-engineer Data & AI practice from zero.
Proof: banking RAG, GPT-4o realtime voice, the 25-engineer case study.
Explore the practice →Zero-downtime migrations, consolidation and performance rescue on multi-terabyte production systems — with empirical verification instead of hope. The depth most modern architects never built.
Proof: Telepizza, 12 servers to 2, ALK Abelló at CMMI-III, Madrid's 2 TB telecontrol.
Explore the practice →For systems in trouble: elusive bugs blocking production, performance collapses, integration failures — and applications whose original developers are long gone. I study the code, document what nobody documented, and extend it safely while the business keeps running.
Proof: taking over Geofactory's platform with zero support from its authors, years extending Altra's orphan production system.
Explore the practice →Large, data-heavy enterprise web applications: UI architecture, grids, charts, accessibility, long-lived products. Framework-level Ext JS authority — including years developing the framework itself for Sencha and formal MVP recognition.
Proof: multi-year Ext JS framework development, ExtJS architecture review for a Fortune 500 energy multinational, published plugins.
Explore the practice →Codebase audits, organizational diagnostics and confidential executive reports — as the client's independent senior, not the vendor's. Technical due diligence, provider oversight, pre-sales and SOW authorship for consultancies.
Proof: the dual audit that unlocked ~€2M in new contracts, a three-product DevOps investigation.
Explore the practice →Almost every engagement starts with a scoped first step measured in weeks — an audit or architecture review that tells you the truth before you commit to anything large.
Fixed-scope review of a codebase, architecture, database estate or organization. Weeks, not quarters. The report is written for both engineering and the board.
Long-running senior authority inside your program: technical direction, reference designs, key implementations, code review, delivery accountability.
Take over what's failing — honest diagnosis, re-architecture where needed, and ownership until it ships. My name on the outcome.
For consultancies and vendors: solution architecture, proposal and SOW authorship, and the senior technical presence that closes late-stage enterprise deals.
Most clients aren't — real problems rarely respect category boundaries. Describe the situation and I'll tell you honestly what I'd do, and whether I'm the right person for it.
