Over 15 years of building and scaling distributed systems has taught me what makes software last, and exactly where it breaks. These days I pair that hard-won judgment with modern AI tooling to ship faster without compromising on code quality. The AI handles the boilerplate and accelerates execution, but I make the architectural calls and keep the quality bar high. Most of my work lives on the backend, usually at the architecture and distributed-systems level. I have built email and SMS delivery platforms, real-time analytics pipelines, API gateways, scraping fleets and lead routers, the kind of systems that have to stay up while serving millions of people a month. One of mine pushes 400k+ messages a day across six providers and never sends a duplicate. Another serves 3.5M+ requests a day. That reliability is not luck, it is the part of the job I enjoy most: backpressure, idempotency, failover, graceful shutdown, the unglamorous things that decide whether a system survives a bad day. My daily drivers are Go, Node.js and Python. I don't chase hype, I use the right tool for the job. I also deploy what I build. These days that mostly means AWS on ECS with Docker, with the whole environment as Terraform code, though I have run everything from bare Linux boxes to serverless Lambda. I have also spent years as a third-party code reviewer on Upwork, auditing PHP, Python, Node.js, Go and Java codebases for teams who just want a second set of eyes before they trust the thing in production. What you get working with me: - The speed of AI-accelerated execution with the judgment of 15+ years of real production systems behind every decision - A backend architect who owns the hard parts end to end, from API design to the queues and workers behind it - Clean, layered, maintainable code, not clever code your next developer will curse - Honest communication and clear trade-offs, I will tell you when a simpler option is the right one - Someone who deploys, monitors and operates what he builds, not just hands off a repo AI makes a lot of people faster right now, but speed without judgment just ships bugs quicker. The edge is knowing what to build, what to skip, and where it breaks under load. That is what 15 years buys you, and it is exactly what I bring. Send me the details and let's talk about what you are building.
