About me!

I am a software developer specialized in Go and Ruby, focused on building distributed systems, microservices, and REST APIs for enterprise backends.

My career has been shaped by reliability, automation, and software that supports critical operations. With more than 50k hours of experience in demanding environments, I have supported 1,200+ clients and contributed to solutions designed to scale in complex production settings.

I apply practices such as hexagonal architecture, SOLID principles, observability, clear service contracts, and DevOps culture to build resilient, maintainable systems ready for growth.

I work at the intersection of engineering and operations: automating processes at scale, improving workflows, and reducing the impact of incidents. In production, that translates into 200M+ automated executions, 16M+ operational events managed per month, and measurable gains, including 30% lower impact and a 35% productivity improvement.

Across mission-critical environments, I have combined software engineering with operational excellence to help teams improve delivery speed, reduce operational friction, and sustain high-availability systems at scale.

Software Development Engineer - Kyndryl

July/2023 - Present

I develop backend services in Go for automation platforms and critical operations, with a focus on scalability, reliability, and predictability in production.

I work with high-volume workloads, concurrency, and strict availability requirements, contributing to resilient, observable distributed systems that are easy to evolve over time.

I also participate in architectural decisions and service improvements, applying practices such as hexagonal architecture, clear contracts, separation of responsibilities, and data-driven operational thinking.

My background in SRE and DevOps complements my engineering work, allowing me to see the system end-to-end — from code to production.

The main goal is to turn complex problems into simple, sustainable solutions that create measurable impact in efficiency, stability, and delivery.
