Product
High-Throughput REST APIs
Go HTTP services designed for high concurrent request volume with predictable latency and modest memory use relative to equivalent dynamic-language services.
Go (Golang) Development — High-Throughput Backend Services Built for Scale
We build Go-based backend services, REST APIs, and gRPC microservices for applications requiring extreme throughput, low latency, and minimal infrastructure cost.

What We Build
What We Build With Go (Golang) Development
Production applications across product types — scoped to your users, stack, and growth stage.
6 product types — compare what we ship with Go (Golang) in production.
- Platform
gRPC Microservices
Protocol Buffer-defined gRPC services for internal service-to-service communication in microservices architectures running on containers or Kubernetes.
- SaaS
Payment & Financial Processing
Concurrent payment processing systems where correctness, performance, and resource efficiency are simultaneously required.
- Commerce
Real-Time Data Pipelines
High-throughput data ingestion services, stream processors, and event-driven systems handling continuous event volume with backpressure-aware design.
- Internal
CLI Tools & DevOps Tooling
Go-based command-line tools, Kubernetes operators, and infrastructure automation with fast startup and distribution as single binaries.
- Design
Networking & Infrastructure Services
Proxies, load balancers, custom protocols, and networking utilities where Go's concurrency model and performance are uniquely suited.
WHY CODEFLAMME
Not Another Offshore Vendor
We know the hesitation. Here's exactly how we're different.
You Talk to the People Building It
No account managers relaying messages. You're in direct contact with the founder and senior engineers on your project — every sprint, every decision.
No Bench Rotation
The team that scopes your project is the team that ships it. We don't swap engineers mid-project to free them up for someone else.
NDA Before We Talk Details
Your idea and IP are protected from the first real conversation — not after contracts are signed.
Full IP, Zero Strings
Every line of code, every design file, transfers to you on delivery. No licensing, no retained rights, no surprises.
Our Capabilities
Our Go (Golang) Development Services
Core delivery areas for Go (Golang) — architecture, implementation, and production hardening.
- 01
Go API Design
Idiomatic Go REST API design with net/http, Gin or Echo — proper error handling, middleware patterns, and request validation.
- 02
Concurrency Patterns
Goroutines, channels, sync primitives, and context propagation for safe, high-performance concurrent Go applications.
- 03
gRPC & Protocol Buffers
Service definition with Proto files, bidirectional streaming, and gRPC-Gateway for JSON/REST compatibility.
- 04
Database Integration
pgx for PostgreSQL, GORM for ORM use cases, Redis, and sqlc for type-safe SQL code generation.
- 05
Testing
Table-driven tests, testify, mock generation with mockery, and integration tests using testcontainers-go.
- 06
Observability
OpenTelemetry instrumentation, Prometheus metrics, structured logging with zap or slog for production Go services.
When to Choose
When Go (Golang) Development Is the Right Choice
Decision scenarios where Go (Golang) is the strongest fit — and why it earns the recommendation.
SCENARIO 01
Primary use case
You need extreme throughput
Go is a strong fit when traffic volume and CPU efficiency are the primary drivers — especially for services that would otherwise need many more instances in a higher-overhead runtime.
02
Scenario
You need low infrastructure cost
Go's modest memory footprint and efficient concurrency often means fewer, smaller instances — material cost reduction once traffic is steady and measurable.
03
Scenario
You are building microservices in Kubernetes
Go's concurrency model, fast process startup, and static binaries make it a natural fit for containerised services alongside Docker and Kubernetes tooling.
04
Scenario
You need concurrency without complexity
Go's goroutines and channels provide safe concurrency without the complexity of threads, locks, and callback hell.
In Practice
How We Use Go on Real Builds
Concrete Go service shapes we ship, when Go beats Node or Python, and how containers and cloud fit the delivery path.
Go work we deliver is usually infrastructure-adjacent product code: REST or gRPC APIs under sustained load, payment processors, ingestion workers, and operators or CLIs as single binaries. Packages stay idiomatic — clear errors, context propagation, table-driven tests — with structured logs and OpenTelemetry from the start.
Go fits when throughput, memory budget, or cold-start behaviour dominate. Node remains better for I/O-heavy product APIs on a JavaScript team; Python when ML libraries own the domain. Go services sit beside other stacks over gRPC or queues, ship as Docker images on Kubernetes, and run on AWS with managed load balancing and autoscaling.
Typical CodeFlamme shapes include rate-limited public APIs in front of Postgres, webhook fan-out workers, and sidecar-style auth or policy services next to Nest or Django apps. We keep protobuf or OpenAPI contracts shared with TypeScript clients so UI teams do not reverse-engineer payloads. CI builds static binaries into slim images; health and readiness probes follow the same Kubernetes patterns we use for other languages. When a product needs both a Go edge service and a Node BFF, we put the latency-sensitive path in Go and leave product orchestration where the team already ships TypeScript.
- 01
Docker / Kubernetes
Go binaries containerise cleanly — small images, fast startup, and straightforward health checks for Kubernetes Deployments and Jobs.
- 02
AWS
We typically deploy Go services on AWS with ECS or EKS, ALB/NLB, managed Postgres or Redis, and CloudWatch or OpenTelemetry exporters.
- 03
API Integrations
Go services often own high-volume integration edges — partner APIs, webhooks, and fan-out workers — within our API integration practice.
