What I'm looking for

I seek a hands-on internship or junior role focused on backend, cloud infrastructure, and Web3; I value collaborative teams, measurable impact, mentorship, and opportunities to scale systems.

I am a software developer specializing in backend systems, cloud infrastructure, and Web3 integrations. I build scalable, maintainable architectures that prioritize performance and observability.

In my current role I led implementation of a serverless real-time communication module and built asynchronous pipelines with SQS & SNS, reducing API latency by 25% and accelerating feature delivery by 30% through DDD and Clean Architecture.

Previously I developed payment systems (PIX), created an Amazon SES email platform that reduced costs by 95% with a 0.1% bounce rate, and scaled game servers to 1,500 concurrent players using Redis and Postgres.

I contribute to open-source projects used by thousands of users and enjoy working in fast-paced teams, hackathons and product-driven environments. I am looking to apply backend, DevOps and cloud skills to deliver measurable impact.
