Hi! I am Cristian.

I build distributed systems that don't just work—they scale, perform, and deliver measurable business impact.

With 5.5+ years of commercial Golang experience, I specialize in architecting high-performance microservices that handle billions of events in real-time while maintaining 99.9% uptime. Companies partner with me when they need systems that operate under heavy load with absolute reliability, or when their current infrastructure is becoming a bottleneck to growth.

WHAT I BRING TO THE TABLE

Performance Optimization That Drives ROI
I don't just write code—I eliminate bottlenecks that cost companies money and user trust. At Endava, I optimized database queries on tables with billions of rows, reducing execution time from timeout (30+ seconds) to sub-second response (<350ms). This wasn't just a technical win; it transformed system usability and unlocked new capabilities for the business.

Kubernetes Expertise That Scales Operations
I've built production-grade Kubernetes solutions from the ground up, including custom operators that monitor and manage complex deployment pipelines. My continuous deployment platform achieved 85%+ deployment success rates, directly improving team velocity and reducing operational overhead.

Distributed Systems That Handle Real-World Load
Whether it's metering ingestion services processing real-time events for usage-based billing (90%+ accuracy) or distributed file systems handling 1GB+ files with 99.9% uptime, I design architectures that perform under pressure. I use profiling tools like pprof and flamegraphs not as afterthoughts, but as core parts of my development process.

TECHNICAL LEADERSHIP

Beyond individual contributions, I drive architectural decisions, mentor engineering teams, and deliver scalable microservices from concept to production. I've led technical initiatives across cross-functional teams, conducted comprehensive code reviews, and established best practices that elevate entire engineering organizations.

MY TECH STACK

• Languages: Golang (6+ years), Ruby, JavaScript
• Distributed Systems: gRPC, Kafka, NATS, Microservices Architecture
• Container Orchestration: Kubernetes (including custom operators), Docker, Helm, Tekton
• Databases: PostgreSQL (advanced optimization), MongoDB, CassandraDB, Redis
• Performance: pprof, Flamegraphs, Prometheus, Grafana
• Cloud: AWS, Azure, CI/CD Pipelines

ENTREPRENEURIAL MINDSET

Beyond my engineering roles, I've built ABAXUS, a usage-based billing platform, giving me unique insight into how technical decisions impact business outcomes. This perspective helps me prioritize work that delivers real value, not just technically interesting solutions.

LOOKING FOR OPPORTUNITIES WHERE:

✓ Performance optimization directly impacts user experience and business metrics
✓ Distributed systems need to scale to handle millions of users
✓ Technical leadership and architectural decisions drive product success
✓ Teams value continuous learning, mentorship, and engineering excellence
