José Escrich

Built by someone who has lived inside the production reality of enterprise software.

I started writing software professionally in the late 1990s. Since then I have worked inside Microsoft engineering groups, designed core systems for banks and government agencies, and led engineering teams across the Americas.

I have seen what works, what does not, and what only looks like it works until traffic doubles. That is the perspective I bring to every engagement.

  • 16 years as Microsoft Partner — Patterns & Practices, Azure, Office 365
  • Founder of US3 Group and WHAWIT
  • Microsoft Visual Studio Extensibility Contributor Award
03How I help

Three things, done seriously.

01 — Architect

Architecture that survives growth

I design systems for the load you have today and the scale you will have in three years — pragmatic, well-bounded, and grounded in trade-offs your team can actually defend in front of the board.

02 — Build

Hands-on, shipping code

I am still in the editor every week. Architecture diagrams that never meet a compiler are theatre — the value is in the production deploys, the migrations that don't break customers, and the code reviews that lift the team.

03 — Lead

Teams that compound

I help engineering organizations turn into something that gets stronger every quarter — through mentoring, technical hiring, process work, and the quiet leadership that keeps senior engineers around.

04Services

Engagements I take on.

Most engagements start with a strategy call. From there we shape the right scope — project, fractional, or hourly — for the problem in front of you.

From concept to implementation, I architect and build scalable, secure, and high-performance software solutions that meet your business needs.

  • Software architecture design
  • Microservices architecture
  • Cloud-native architecture

Custom software solutions that align with your business goals and deliver exceptional user experiences across web, mobile, and APIs.

  • Full-stack development
  • Mobile app development
  • Web development
  • API development

Smooth, efficient operation of your software through DevOps and infrastructure expertise — from IaC to observability.

  • Infrastructure as Code (IaC)
  • Continuous Integration & Delivery
  • Monitoring & Logging

Expert-level technology leadership without the full-time commitment. Fractional CTO services to design, scale, and future-proof your stack.

  • Technology stack assessment
  • Architecture design & review
  • Digital transformation strategy
  • Cloud migration planning

One-on-one mentoring tailored to developers growing into leadership and senior engineers fine-tuning their technical edge.

Run a 30-minute architecture review against your real stack.

Bring a real problem — a system you are scaling, a migration you are nervous about, a team you want to level up. We will spend the time well.
