Distributed engineering teams replacing slow JSON-over-HTTP inter-service calls with strongly typed binary protocols frequently search to hire a freelance gRPC, Protocol Buffers (Protobuf) & ConnectRPC microservices programmer. I am Aldian Fazrihady, a Senior Freelance Backend & Systems Programmer.

Core gRPC, Protobuf & ConnectRPC Capabilities

  • Buf.build Schema Governance & Codegen: Enforcing backward-compatible `.proto` evolution (`buf lint`, `buf breaking`) and generating type-safe stubs across Go, Python (`grpc.aio`), and TypeScript (`@connectrpc/connect-web`).
  • Bi-Directional Streaming & Multiplexed HTTP/2: Building low-latency streaming pipelines for AI inference tokens, financial market data, and IoT telemetry.
  • ConnectRPC for Browser & Server Unification: Exposing services that speak both native binary gRPC (service-to-service) and clean JSON/HTTP POST for browser React clients without Envoy proxy complexity.

Frequently Asked Questions

Why choose ConnectRPC over traditional grpc-web?

ConnectRPC works natively with standard browser `fetch()`, supports both Protobuf binary and human-readable JSON in Chrome DevTools Network inspector, and speaks standard gRPC on the wire.

How do I hire you as a freelance gRPC & Go/Python programmer?

Hire me via Upwork.
