What I'm looking for

I looking for a company solving real problems, I also believe in flexible work time. I want a get a job abroad.

I'm a Staff Software Engineer with over 10 years of experience building high-scale fintech systems and leading hands-on engineering teams. I focus on reliable, serverless-first architectures and measurable product outcomes.

I've architected platforms that manage millions in active loan contracts and supported high monthly transaction volumes, partnering with executives to set company-wide architectural standards. My work spans ledger and payment integrations, bank transfers, and whitelabel payment APIs.

I'm proficient with AWS Lambda, DynamoDB, SQS, event-driven design, microservices, TypeScript/NestJS, .NET/C#, and relational databases, and I build analytical dashboards and retention-focused metrics that reduce operational load. I favor pragmatic, scalable solutions that improve reliability and business metrics.

I'm a hands-on leader who mentors teams, promotes agile transformation, and delivers production-grade systems under high volume. I communicate in English and am actively learning Spanish to broaden collaboration across teams.
