Technology that works for your business.
I help businesses simplify systems, solve problems and build operations that are more efficient, secure and ready to grow.
What I do
From technical strategy to solutions in production.
I work at the intersection of software, infrastructure and business, identifying operational bottlenecks and delivering improvements focused on impact, reliability and long-term maintainability.
Reliability and performance
Investigating incidents, resolving recurring issues and optimizing systems to reduce disruption and improve the experience of their users.
Security and incident response
Identifying risks, prioritizing vulnerabilities and implementing safeguards, with timely action when operations demand it.
Automation and delivery
Improving processes and delivery with CI/CD, automation and AI, choosing solutions that deliver practical value for teams.
Results in production
Experience that delivers impact.
I work close to production, combining analysis and execution to improve what matters to the business.
Performance
Faster delivery in a critical system
Rebuilt a pipeline processing millions of events per day, moving data delivery from minutes to real time. The asynchronous Python solution on ARM simplified the architecture, improved resilience and cut costs by a factor of 32.
30%
Infrastructure cost reduction
Optimized Oracle Cloud Infrastructure (OCI), reducing costs by approximately 30% and saving nearly BRL 200,000 per year.
Resilience
Stability and faster response
Helped transform an operation affected by frequent, prolonged outages into a more stable platform. Monitoring and alerts enable faster detection and resolution of occasional incidents, supporting a high-quality SLA.
Security
Technical initiative that drives decisions
Identified the need to strengthen information security and brought it to management, balancing risks, costs and options. The initiative evolved to include a SIEM and a dedicated SOC team.
I also monitor vulnerabilities and act proactively. In cases such as Log4Shell and PHP2Shell, I alerted the team and led the application of fixes.
