Hire Golang Developer — concurrent backends without the drama
Go services that stay boring under load: I design concurrent backends around goroutines, channels, and gRPC contracts, shipped as single binaries with Postgres persistence. You get predictable latency, clear observability, and code your team can extend. Typical first release in 2–4 weeks — a production API with auth, migrations, and dashboards.

I'm Omer Muneer Qazi, a Dubai-based Fractional CTO & Solutions Architect with 15+ years of experience and 100+ projects delivered across 6 countries. For memory-safety-critical components alongside Go, you can also hire Rust developer capacity, or see the full bench.
Go backends, built the boring way
Concurrent API design
Goroutine worker pools, channel pipelines, and context-aware cancellation designed around your throughput targets. Every handler is reviewed for data races and deadlock patterns before it reaches staging, with load-test baselines documented.
gRPC & REST services
Protobuf contracts with Buf linting, versioned REST endpoints via Gin or Echo, and typed clients for frontend and mobile teams. Breaking changes are gated behind contract tests so integrations never silently drift.
Data layer & migrations
Postgres schemas with sqlc or pgx, migration scripts with rollback coverage, and Redis caching where hit rates justify it. Connection pooling and prepared statements are standard; N+1 patterns get flagged in review.
Observability & reliability
Structured logging, Prometheus metrics, and OpenTelemetry traces wired into dashboards from day one. Graceful shutdown, health probes, and retry policies with backoff turn deploys into non-events.
Single-binary deployments
Static binaries built with version-stamped releases, multi-stage Docker images, and GitHub Actions pipelines. Kubernetes manifests or plain VM deploys — the artifact stays identical across environments.
Handover & team enablement
Architecture decision records, runbooks, and recorded walkthroughs so your engineers own the system. Pairing sessions on concurrency pitfalls mean the codebase stays healthy long-term after handover.
From kickoff to production in weeks
A structured engagement with no surprises — you’ll always know what’s happening and what’s next.
Discovery & architecture
A technical deep-dive into your domain, traffic expectations, and existing systems. You receive a service map, data-model sketch, and a phased delivery plan with clear milestones.
Sprint delivery
Weekly iterations with demoed working software: APIs, migrations, and tests landing in your repository every Friday. Progress is measured in merged PRs, not status slides.
Hardening & load testing
Race-detector runs, fuzz testing on parsers, and k6 load tests against staging before launch. Alerts and runbooks are validated against real failure injection.
Launch & support
Supervised rollout with feature flags and instant rollback, then a support window where incidents are triaged with your team. Knowledge transfer closes the engagement.
Why hire a Golang developer through a fractional CTO
Go rewards discipline and punishes cleverness. Years of building concurrent services taught me which patterns page you at 3 a.m. — so I default to bounded queues, explicit timeouts, and narrow interfaces. That judgment, across 100+ projects and $25M+ in client revenue enabled, is what a fractional engagement buys.
I work embedded in your Slack and repository, demo weekly, and document decisions as ADRs. Expect direct, senior-level communication — no account managers. Contact me to scope your backend.
Frequently asked questions
Why Go instead of Node or Python for my backend?
Go's static binaries and goroutine scheduler handle thousands of concurrent connections with low memory overhead. For I/O-heavy APIs and infrastructure tooling, it outperforms interpreted runtimes while keeping deploys trivially simple.
Can you take over an existing Go codebase?
Yes — I start with a codebase audit covering concurrency hazards, dependency hygiene, and test coverage. You get a prioritized remediation plan, then I fix the highest-risk items first while shipping features.
Do you work with our in-house team?
That's the default mode. I embed in your repo and rituals, review PRs with teaching comments, and run pairing sessions on Go idioms. Your engineers end the engagement stronger than they started it.
How fast can we get a production API live?
A focused service — auth, CRUD, and background jobs — typically ships in 2–4 weeks. Complex domains with event-driven flows take 6–10 weeks. Timelines are fixed at kickoff, not discovered mid-flight.
How do we start?
Send your requirements through the contact page for a scoped proposal. Discovery calls are technical — we talk through your architecture, constraints, and timeline before any commitment.
