Senior Go gRPC Web App

@AwaisChaudhry

Hello, I'm Muhammad Awais, and I can own your gRPC layer end to end with idiomatic Go, strong architecture, and robust tests. I will design and implement gRPC endpoints and middleware, enforce clean module boundaries, and add observability hooks (metrics, traces, logs) so your service stays observable in production. I’ll keep the build pipeline simple using Go modules, Make, and Docker, and I’ll provide clear ADR documentation and concise run instructions. My approach: audit current code, define stable service contracts, implement idiomatic Go patterns, add comprehensive unit and integration tests (targeting ≥90% line coverage), wire in Prometheus metrics and tracing (OpenTelemetry where appropriate), and create lightweight, maintainable architecture with clear documentation. I will mentor teammates where time allows and provide Russian-English updates as needed for smooth collaboration. What is the expected service maturity for the first milestone (contracts, middleware, tests, and observability) and any preferred tracing backend or metrics naming conventions? Rate limits or QoS requirements I should honor? Any existing gRPC service contracts or proto definitions I must align with? Which Go version and CI/CD tools are in current use? Are there security or auth requirements for the gRPC endpoints? Do you prefer a specific logging format or structure? Any regional data residency constraints? What is the expected latency budget for the core paths? Do you have preferred ADR stru

@kareemmaize

Hi there For a production Go system, the most critical part is ensuring the gRPC layer is not just functional but architecturally clean and future-proof. Contracts, middleware, and observability must be designed deliberately so services scale without fragmentation. I would structure each gRPC package with clear domain boundaries, strict interface definitions, and dependency injection to keep services testable and modular. Middleware would handle authentication, tracing, logging, and error normalization consistently across endpoints. Observability would be integrated using OpenTelemetry for tracing and Prometheus metrics exposure, ensuring seamless Grafana visualization. CI would enforce linting, static analysis, and ≥90% coverage through table-driven tests and integration scenarios. Docker builds and make targets would remain simple and reproducible. My approach prioritizes idiomatic Go, clean ADR documentation, and production reliability from day one. Once I review the current repository structure, I can propose concrete refactoring steps and timeline alignment. If this aligns, let’s discuss in detail via private chat.

@juanjosec63

Hello, I’m excited about the opportunity to contribute to your project. With my expertise in building production-grade Go services and designing clean, idiomatic gRPC architectures, I can take full ownership of your service layer, ensuring well-structured contracts, middleware, test coverage above 90%, and code that stands up to rigorous senior-level review. I’ll implement structured observability using Prometheus metrics, distributed tracing, and structured logging, while keeping Docker-based builds and CI pipelines simple, reproducible, and production-ready. You can expect disciplined architecture decisions, clear ADR-style documentation, and maintainable, high-performance Go code designed for long-term scalability. Best regards, Juan

@kamran2012

Hello there, I will take ownership of the gRPC layer, designing service contracts, implementing handlers and middleware, wiring observability into every endpoint, and maintaining test coverage above 90 percent across all new packages. For the middleware, I will chain gRPC interceptors, one each for tracing, Prometheus metrics, logging, and error mapping, so handler code stays focused on business logic and adding a new cross-cutting concern means writing one interceptor, not editing every service. Questions: 1) Are you using buf or protoc for proto compilation and linting? 2) Is the observability stack already running (Prometheus + Grafana), or does that need setup too? 3) What is the current size of the codebase, roughly how many services exist? Looking forward to your response. Best regards, Kamran

@maxscender

I can help you. I understand the nuances of production-grade Go, specifically the risk of "shallow" 90% test coverage that tests implementation details rather than behavior. I will prioritize clean interface boundaries and proper context propagation to ensure your observability hooks capture actual bottlenecks without inflating latency. A hidden challenge in gRPC-heavy architectures is often proto-file versioning and maintaining backward compatibility across service boundaries; I’ll implement a structured workflow to prevent breaking changes. We can discuss these technical trade-offs in Russian to ensure no nuance is lost. My focus will be on ensuring your gRPC interceptors handle authentication and telemetry efficiently without turning into a maintenance burden.
