02 / THE JOURNEY

I learned to see
the whole system.

I started with the interface. Each chapter widened what I could own: the product, the architecture, the team, the operation and the business decision behind it.

Start in 2026 and scroll right to trace the experience behind the work.
01
2025 — 2026Founder & Principal Engineer · Ana M & Focando

I brought every layer together.

I built two SaaS products from zero to production and owned product, UX, architecture, implementation, team building, releases and operations. That became the foundation for my work with production AI: LLM routing, speech workflows, cost telemetry and agent-driven engineering with human control.

02
2021 — 2022Product Owner · Rede Vistorias

Product ownership sharpened what to build — and why.

Owning discovery, roadmaps and specifications for a SaaS product made the connection between business goals and engineering execution explicit. I learned to remove ambiguity, make tradeoffs visible and give a team decisions it could actually implement.

03
2019 — 2025Tech Lead · BairesDev & McFadyen Digital

Scale taught me how strong teams move.

Across international client environments, I adapted to different products and codebases, led distributed engineers and delivered React and React Native systems. The work went beyond the interface: performance, APIs, observability, production incidents, code review and the judgment to keep complex delivery moving.

04
2016 — 2022Founder & CTO · Work and Code

Then I became responsible for the whole delivery.

Running a software company changed the size of the problem. I worked with clients on discovery, scope and architecture, built web and mobile products, led and mentored developers, and balanced technical choices with estimates, capacity and delivery risk — while staying hands-on.

05
2004 — 2016Design, front-end & independent delivery

I started where people meet software.

Web design, interfaces, campaigns, interactive experiences and early products taught me to connect usability with implementation. I learned to listen to the user, understand the business goal and carry an idea all the way to something people could use.

THE THREAD THROUGH IT ALL
I can enter through product, architecture, delivery, performance, people or AI — and connect the pieces until the company can move forward on its own.

Wide context.
Clear ownership.

Christian Spilhere

I can join as a fractional CTO, Tech Lead, Product Owner, architect, hands-on engineer or mentor. The role depends on the problem and the capability your company needs next.

What stays constant is the approach: understand the business goal, work through the real technical constraints, make decisions visible and leave the people continuing the work stronger.
