Emir R.

I audit Go codebases, help teams make architecture decisions, and work as a fractional CTO or engineering lead. I maintain Sentry's official Go SDK and have over 15 years of professional engineering experience, including 11 years with Go. Clients bring me in when they've inherited a Go system and want an independent review before building more on it, when a migration needs careful technical judgment, or when their engineers need experienced leadership. An audit gives you findings ranked by risk and effort, with code examples where they make the next step clear. I've done this work for companies on Upwork and outside it. Relevant work: - Kayse: Director of Engineering, leading a team of 15 engineers building an AI legal tech platform. I own architecture, technical direction and engineering standards. - PolymerSearch: architected a platform that turns spreadsheets into interactive web apps and led a team of 7+ engineers as Head of Engineering. - Work&Co: built a Go webhook integration that reduced API load by 70%. - Qopla: code reviews. GiveCard: Go backend work and guidance for engineers. My core stack is Go, PostgreSQL and REST/gRPC APIs, with Python, Node.js and TypeScript where a product calls for them. I also have extensive Claude API experience and have worked on LLM cost optimization. Audits, architecture reviews and fractional CTO or engineering leadership work are personal engagements with me. When a project needs a delivery team, it runs through ByteBuds, where I'm co-founder and CTO. ByteBuds provides the engineers and I oversee architecture and delivery. We agree the engineers and their allocation before starting. Send me a short description of the system, what's getting in the way and what you need to achieve. We can start with a focused audit or a clearly scoped first phase.
