- Infrastructure review
Observability and Reliability
Make failures easier to detect, understand and fix before they become costly.
- Metrics and dashboards
- Alerting workflows
- Operational visibility
Technical work tied to operational impact
The goal is more stable systems, lower operational drag, and better delivery capacity.
Faster engineering delivery (DevEx)
Trimming PR cycles, isolating flaky tests, tuning CI resource compute and building internal developer platforms that minimize cognitive load.
Reduced system bottlenecks
Build explainable platforms with explicit system boundaries.
Establishing a clean dependency graph isolates component logic, minimizes cognitive load and keeps codebases adaptable at scale.
Improved production reliability
Safeguarding platform stability so developers can ship with confidence.
Clearer system ownership
Make architecture, dependencies and failure modes easier for the team to understand.

John has a strong bias for action. He routinely takes the initiative to solve tough problems, gathers feedback, and delivers high-quality results quickly. He’s also a highly collaborative teammate who keeps everyone aligned through clear documentation, open discussion and proactively giving feedback to elevate those around him!
John joined our team at the end of 2024 and immediately raised the bar introducing tools and good practice in backend code development and CI that brought structure to our codebase from day one. As a Senior Backend Engineer, he led the hardest parts of our platform revamp, turning chaos into clean, scalable architecture with solid bases to continue growing. Any team building serious backend systems would be lucky to have him.
I worked with João at Flex for 2 years building a web-based ML scoring system for cold-call campaigns. He led architecture (front/back) and implemented nearly everything. Skilled, proactive, and collaborative, he delivered fast and solved a major bottleneck. I'd gladly work with him again.
João was my colleague for 2.5 years at Flex, and his skills are impressive. He was always able to come up with polished and comprehensive solutions from the get-go. He single-handedly built a model serving infrastructure from scratch, which was responsive, intuitive and robust all at once. He can certainly support pretty much any technical challenge you throw at him.
Good architecture must be explainable, reliable and future proof.
Resilient backend architecture is the ultimate engine for developer velocity.
Flexible Engagement Models
Two ways to work together, depending on your needs and stage.
Project-Based Engagement
Best for defined problems such as migrations, architecture reviews, performance improvements, or delivery of a specific technical initiative.
Embedded Engineering
Best for teams that need senior hands-on support inside an existing product roadmap or engineering workflow.
- Work directly with your engineering team
- Contribute to backend and infrastructure delivery
- Improve reliability, tooling, and architecture over time
- Flexible support based on team needs

You will benefit from my services if
Engineering velocity is slowing down
Time from ticket to deployment is too long, your engineers are unsatisfied and are struggling with tooling.
Systems are difficult to scale and maintain
Your systems are not easily explainable and confusing, there is no clear design patterns or structure. Engineers must touch numerous files to make changes.
Deployments are risky or inconsistent
There is no clear automation in place, deployments are inconsistent and risky. Race conditions affect your deployment which risks production uptime.
Your system is not properly monitored
You cannot measure how your systems are performing, you have no visibility into their health. You cannot detect spikes and anomalies in your system, nor troubleshoot them when latency issues arise.
Tools organized by the problems they solve
- Python, Go, APIs, services
- AWS, GCP, Docker, Kubernetes
- PostgreSQL, MongoDB, Redis
- Prometheus, Grafana, Alertmanager
- CI/CD pipelines, Developer tooling, Workflow automation
