Carlos S.

Backend engineer specializing in building scalable APIs and microservices architecture. I design and maintain high-performance systems that reliably handle millions of requests while maintaining data integrity and security.

Architectural Expertise:

• Microservices Design: Building loosely coupled, independently deployable services

• API Development: RESTful APIs, GraphQL, gRPC, event-driven architectures

• Databases: MongoDB, PostgreSQL, Redis, database optimization and sharding

• Message Queues: RabbitMQ, Kafka for asynchronous processing and event streaming

• Container Orchestration: Kubernetes, Docker Swarm, managing complex deployments

Performance & Scalability:

I've architected systems that scale from thousands to millions of concurrent users. My expertise includes database optimization, caching strategies, load balancing, and monitoring. I've reduced API response times by 70% through strategic optimization and implemented systems that handle 100K+ requests per second.

Key Achievements:

• Designed microservices architecture that reduced deployment time from hours to minutes

• Implemented event-driven system processing 50M+ events daily with 99.99% uptime

• Optimized database queries reducing latency by 65% and cutting infrastructure costs by 40%

• Led migration from monolithic to microservices, improving team velocity by 3x

I'm experienced in working with cross-functional teams, mentoring developers, and establishing best practices for code quality, testing, and deployment. I'm also passionate about DevOps practices and infrastructure as code.
