Programming & Development Programming & Software

Senior Backend Engineer

$30/hr Starting at $50

I design and build high-performance backend systems that remain stable under real-world load, not just in development, but in production.


With strong experience in Java (8-21), Python, and distributed architectures, I help startups and businesses build scalable, reliable, and efficient systems that handle high traffic and real-time data processing.


My core expertise includes:


• Backend development using Java (Spring Boot)  

• REST & SOAP API design and microservices architecture  

• Real-time systems (WebSockets, streaming pipelines, event-driven systems)  

• Distributed systems and high-concurrency architectures  

• Performance optimization (low latency, GC tuning, throughput improvement)  

• System integration (third-party APIs, messaging systems, data pipelines)  

• Kubernetes and containerized deployments  


Technologies I work with include:

Java, Spring Boot, Kafka, RabbitMQ, Redis, PostgreSQL, MySQL, MongoDB, Oracle, Linux


I specialize in solving complex backend challenges such as:

• Systems slowing down under load  

• APIs that don’t scale efficiently  

• Real-time data processing and streaming issues  

• Backend bottlenecks and instability  

• High memory usage and garbage collection problems  


What sets me apart is my focus on performance and reliability. I don’t just build features. I design systems that scale, recover from failure, and perform consistently under pressure.


I apply best practices such as efficient resource management, fault tolerance (retry, fallback strategies), and observability (logging, monitoring, metrics) to ensure systems are production-ready.


Recent work includes building real-time WebSocket systems handling 500+ concurrent connections, optimizing backend performance to reduce latency, and designing scalable data pipelines.


If you need a backend engineer who understands real-world scalability, performance, and reliability, I’m ready to help.
