FREELANCE GO & BACKEND DEVELOPER.
I build high-throughput concurrent backends, resilient APIs, and early-stage MVPs in Go and Python. Every architecture is engineered for low latency, zero runtime bloat, and predictable production scaling.
What I Build for Clients
High-Concurrency Go Engines
Bounded worker pools, channel orchestration, and raw socket networking capable of handling tens of thousands of operations per minute without memory leaks or race conditions.
- · Goroutine rate-limiting and context cancellation
- · Custom protocol parsers and packet engines
- · Benchmark-verified memory footprint under load
REST & gRPC API Architecture
Clean, versioned microservices with strict schema validation, structured JSON logging, Prometheus metrics, and automated OpenAPI (Swagger) documentation.
- · Idempotent payment, webhook, and auth flows
- · JWT and API key authentication middleware
- · Sub-10ms p95 latency targets
Database Design & State Management
Optimized SQLite embedded stores with WAL (Write-Ahead Logging) journaling and PostgreSQL databases with indexing strategies, connection pooling, and automated migrations.
- · Historical state diffing and scan history tracking
- · SQL migration tooling and zero-downtime schemas
- · High write-volume transaction safety
Full MVP Delivery (2–4 Weeks)
For early-stage founders who need a backend built right the first time. We turn your product requirements into a production Docker image ready to run on any cloud host.
- · Complete backend service with clean docs
- · Integration tests and GitHub Actions CI workflow
- · Zero vendor lock-in; runs anywhere via Docker
Revealr: 50,000 Ports/Minute Stateful Go Scanner
Revealr is an open-source adaptive network scanner written in Go. It demonstrates low-level raw socket synthesis, rate-limiting concurrency control, and SQLite stateful persistence to detect network drift across scans.
Backend Engineering FAQ
Why hire a Go developer for a backend project?
Go compiles into a single statically linked binary with near-instant boot times and minimal RAM usage. Its built-in concurrency primitives (goroutines and channels) allow backends to handle high concurrent traffic loads with a fraction of the cloud hosting costs required by Node.js or Python runtimes.
Can you work with our existing frontend or mobile app?
Absolutely. I build clean RESTful and gRPC APIs adhering strictly to OpenAPI 3.0 specifications. Your frontend (React, Next.js, Flutter, iOS) integrates seamlessly via strongly typed endpoints.
