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.
