What I'm looking for

I’m looking for remote LATAM opportunities where engineering rigor delivers product impact—building reliable full stack systems, improving performance through serverless and observability, and applying AI-integrated approaches to real workflows.

I’m a Full Stack Engineer with 6+ years building scalable backend services, cloud-native architectures, and data-driven web applications across fintech and IoT. I specialize in Python (FastAPI), Node.js, and the .NET ecosystem, and I focus on production-ready solutions that teams can trust.

In my current role, I design and maintain AWS serverless microservices using AWS SAM and Step Functions, improving critical credit-card workflows and reducing manual intervention by ~40%. I also reduced operational incidents by ~35% through automated monitoring pipelines in CloudWatch (custom metrics, alarms, dashboards) and improved API response times by ~40% via serverless optimization, including async processing patterns and efficient database query design.

I’m hands-on with observability and reliability: I implement structured alerting that reduced undetected errors by ~50% and helped maintain 99.5%+ uptime SLA while triaging and resolving Python runtime and integration errors across distributed services. I also automate operational runbooks and incident-response procedures, reducing on-call escalation frequency by ~30%.

Previously, I built full stack solutions for IoT and internal operations—combining NestJS/Vue and C# .NET MVC with data pipelines on GCP (BigQuery, Looker Studio). With my Udemy certification in Machine Learning & Data Science in Python, I’m increasingly drawn to AI-integrated full stack systems that keep engineering rigor while driving real product impact.
