Senior Backend Engineer | Real-Time Systems & Performance Optimization

Most backend systems work, until real traffic hits them.

That’s where I come in.

I’m a backend engineer specializing in building high-performance systems that remain stable, responsive, and reliable under real-world load. I work with startups and growing businesses to design architectures that don’t just function, but scale.

My focus is on systems where performance actually matters:
• Real-time data processing (WebSockets, event-driven systems)
• High-concurrency environments (hundreds to thousands of connections)
• Low-latency APIs and distributed architectures
• Backend systems that must operate reliably under continuous load

Core expertise:
• Java (Spring Boot) backend development
• API design and microservices architecture
• Distributed systems and messaging (Kafka, RabbitMQ)
• Kubernetes and containerized deployments
• Performance engineering (GC tuning, memory optimization, throughput improvement)

I’m typically brought in when:
• Systems slow down or fail under load
• APIs don’t scale as expected
• Real-time pipelines become unreliable
• Backend performance becomes a bottleneck

What makes me different is simple:
I don’t just build features, I engineer systems that handle pressure.

That means:
• Efficient resource usage
• Fault-tolerant design (retry, fallback, resilience patterns)
• Clean, maintainable architecture that scales with your business

Recent work includes building real-time systems handling 500+ concurrent connections and optimizing backend performance to significantly reduce latency and instability.

If you're building something where performance, scalability, and reliability are critical, I can help you get it right the first time.

Work Terms

I work with clients who value clear communication, quality delivery, and long-term reliability.

Availability
• Flexible working hours depending on project needs
• Available for both short-term tasks and long-term engagements
• Can support systems requiring ongoing maintenance and performance tuning

Communication
• Clear and consistent updates throughout the project
• Quick response during active work periods
• Comfortable collaborating with distributed teams and async workflows

Engagement & Process
• Prefer well-defined requirements, but can assist with system design and architecture
• Break down work into clear milestones for transparency
• Focus on delivering production-ready, scalable solutions

Technical Standards
• Clean, maintainable, and efficient code
• Emphasis on performance, reliability, and scalability
• Proper logging, monitoring, and error handling included
• Version control (Git) and structured development workflows

Payments & Terms
• Open to hourly or milestone-based projects
• For larger projects, milestones are preferred
• Scope changes are handled transparently and agreed upon before implementation

I aim to build long-term partnerships by delivering backend systems that are stable, efficient, and built to scale under real-world conditions.
