Engineering teams building high-throughput payment gateways, real-time bidding/ad-tech engines, IoT telemetry collectors, or Kubernetes operators—or rewriting CPU-bound Python/Node.js bottlenecks—frequently search to hire a senior freelance Golang (Go) programmer. I am Aldian Fazrihady, a Senior Freelance Go & Full Stack Programmer available via Upwork.
Core Golang Production Systems Capabilities
- Idiomatic Go Microservices & Clean Architecture: Building rock-solid services using Go 1.23+, `sqlc` / `pgx/v5` zero-reflection PostgreSQL drivers, Chi / Echo / Fiber / Huma routers, and ConnectRPC / gRPC.
- Structured Concurrency (`errgroup`, Context Cancellation & Worker Pools): Eliminating goroutine leaks, channel deadlocks, and data races (`go test -race`).
- CPU & Heap Allocation Profiling (`pprof`, `benchstat`, Escape Analysis): Shaving garbage-collector (GC) pause times and heap allocations via `sync.Pool`, zero-copy byte slicing, and pre-allocated buffers.
Frequently Asked Questions
Why do we prefer `sqlc` + `pgx/v5` over heavy reflection ORMs like GORM in high-throughput Go services?
`sqlc` compiles raw, PostgreSQL-verified SQL queries into 100% type-safe Go structs at build time—delivering raw `pgx` speed with zero runtime reflection overhead or hidden ORM N+1 surprises.
