Who I am

Staff Engineer
who ships results.

14 years building software products that scale — from early-stage startups to corporate operations across multiple markets. I moved from full-stack developer to tech lead to Staff Engineer, always at the intersection of code, architecture, and teams.

I work with CTOs and founders who need solid technical decisions, architecture that holds under growth, and teams that ship consistently, without relying on individual heroics.

Methodology

How I work

A direct, transparent, result-driven process. Focused on technical decisions that create real and lasting impact.

Let's talk
01

Discovery

I dig into the context: product, team, stack, and the main technical pain points. I map bottlenecks, technical debt, and improvement opportunities through a Staff Engineer lens.

02

Technical Proposal

I present a clear action plan with defined scope, justified technical decisions, and a realistic timeline. No empty promises.

03

Execution

I work hands-on alongside the team. Code, architecture, code reviews, mentoring, and setting technical standards that raise the bar for the entire organization.

04

Team Independence

The team becomes independent. Architecture documentation, established patterns, and training to sustain and evolve what was built.

Let's talk

Have a technical challenge
that needs real depth?

Tell me the context: team, product, main challenge. I'll reply within 24h with a no-commitment call proposal.
