Focus areas

Where I help most

Most teams do not need more engineering activity. They need clearer technical decisions.

  • Stronger leadership cadence and ownership boundaries
  • Clearer architecture direction with practical trade-offs
  • More predictable delivery without sacrificing quality

Diagnosis

Is this your current situation?

  • Team size is growing, but roadmap throughput is falling
  • Product and engineering are no longer aligned on priorities
  • Operational fire-fighting is replacing product progress
  • You need senior technical leadership before a full-time executive hire

What changes

What changes after we start working together

The goal is simple: fewer ambiguous decisions and stronger week-to-week execution.

From vague ownership to clear accountability

Team structure, ownership boundaries, and leadership routines become explicit, so day-to-day execution stops depending on heroics.

From reactive architecture to intentional trade-offs

Architecture decisions move from ad-hoc reactions to a shared direction that reduces risk without slowing delivery.

From fire-fighting to predictable delivery

Technical and operational bottlenecks are addressed in sequence, improving delivery predictability and roadmap confidence.

How I think

How I make engineering decisions

Effective delivery comes from balancing people, process, platform, and product as one integrated system.

  • People

    Team structure, ownership, leadership, and decision-making.

  • Process

    Delivery flow, prioritization, execution quality, and operational rhythm.

  • Platform

    Architecture, reliability, scalability, and technical direction.

  • Product

    Aligning engineering work with product priorities and business goals.

Selected outcomes

These outcomes reflect the operating model applied across different company stages and technical contexts.

2 to 40

Built management layers and stronger ownership during rapid growth.

15d to 3d

Lead time reduction

Improved delivery predictability with process and technical discipline.

-65%

Cloud cost reduction

Cut staging cloud costs while improving operating efficiency.

See detailed outcome examples

  • Scaled engineering organizations during rapid growth

    Grew engineering teams from 2 to 40 people, building multiple layers of management, establishing ownership structures, and improving leadership capacity and hiring quality across different growth stages.

  • Improved delivery speed and predictability

    Reduced lead time from 15 to 3 days by evolving processes, strengthening technical practices, and clarifying cross-team ownership.

  • Evolved legacy systems into scalable platforms

    Led a monolith-to-microservices migration for a CPaaS messaging platform handling 1.5B+ monthly events, improving reliability and long-term operational resilience.

  • Enabled enterprise growth through platform readiness

    Led security and compliance initiatives that enabled the company's largest enterprise contract, supporting BRL 1B/month in payment processing volume.

  • Reduced cloud infrastructure costs at scale

    Led a FinOps initiative that cut cloud infrastructure costs by 65% in staging and 13% in production, while replacing a third-party observability stack and reducing monitoring expenses by 57%.
