Software Engineer | Backend & Cloud (AWS) | Distributed Systems

Building scalable, resilient, and cloud-native solutions with a focus on high-performance backend architectures.

I am a Software Engineer with 4+ years of professional experience specializing in Python, Java, and AWS. My expertise lies in designing and implementing Microservices and Serverless architectures that solve complex business problems.

I am a strong advocate for Infrastructure as Code (IaC), Observability, and Automated Testing as the foundation of any production-grade system. My recent focus has been on bridging the gap between Backend Engineering and Generative AI (RAG).

• Current Role: Software Engineer @ Ritmocor
• Specialization: Distributed Systems, Cloud Infrastructure (AWS), and Event-Driven Design.
• Passion: Creating high-impact software, from local-first AI tools to global-scale fintech/health platforms.

• Languages: Python (Expert), Java (Spring Boot), TypeScript/JavaScript.
• Cloud (AWS): Lambda, API Gateway, DynamoDB, SQS/SNS (Messaging), CloudFormation (IaC), CloudWatch.
• Databases: PostgreSQL, MySQL, DynamoDB, ChromaDB (Vector DB).
• Backend: FastAPI, Flask, Node.js, RESTful APIs, Microservices, Serverless.
• DevOps/Tools: Docker, CI/CD (GitHub Actions, CodePipeline), Linux Administration.
