Most backend engineers can write code. Fewer can architect a system that holds up at scale, survives a traffic spike, and stays observable when something breaks at 2am. That's the gap I fill. I'm a Top Rated Plus engineer on Upwork with a 100% Job Success Score across 34 contracts and 4,600+ hours — working with clients from startups to enterprises across ticketing, marketplace, gaming, and HR domains since 2011. What I actually do: I design and build production-grade backend systems in Go — from the API layer down to the infrastructure. That means event-driven microservices with Kafka or RabbitMQ, containerized deployments on Kubernetes, full CI/CD pipelines, and cloud infrastructure on AWS, GCP, DigitalOcean, or Alibaba Cloud. I don't hand you a working local demo and disappear — I deliver something that runs reliably in production, with proper observability, testing at every layer, and documentation your team can maintain. Specifically, I can help you if: — Your monolith is becoming a bottleneck and you need to decompose it into services that scale independently — You're building a new product and need a senior engineer who can own the backend architecture from day one — Your Kubernetes setup is held together with hope and tribal knowledge, and you need someone to make it solid — You need CICD that actually works — automated testing, container builds, and deployments to staging and production without manual steps Tech I work with daily: Go · PostgreSQL · Redis · Kafka · RabbitMQ · Elasticsearch · Docker · Kubernetes · Helm · Terraform · AWS · GitHub Actions · GitLab CI · gRPC · REST How I work: I ask the right questions before writing the first line of code. I communicate in plain language, not jargon. I've worked in agile teams, solo, and everything in between — I adapt to your workflow, not the other way around. And I treat your codebase like I'll be the one maintaining it, because sometimes I am. If you need a senior engineer who thinks in systems, communicates clearly, and delivers work you won't have to redo — let's talk.
