I’m a Backend Software Engineer with 1.6 years of experience building scalable REST APIs, event-driven microservices, and cloud-native SaaS products. I’ve independently shipped 4 production products with real users, with an emphasis on system design, API security, and distributed systems. At AqueraLabs, I built RESTful APIs (Node.js, Express.js, PostgreSQL) for core SaaS features and reduced p95 latency ~40% through indexing, query optimization, and connection pooling. I architected an event-driven pipeline using AWS Lambda + SQS + S3 to process 5,000+ documents/day, delivering zero-downtime serverless deployments. I also implemented Redis caching (cache-aside, TTL invalidation) to cut DB reads by ~55% and boost API throughput 3× under peak load. I secured multi-tenant SaaS with JWT authentication and RBAC (20+ customer accounts) with zero critical findings in an internal security audit, and I take ownership by authoring OpenAPI/Swagger docs, versioning API contracts, and leading code reviews.
