Hi, I'm Zhenhua Wang

I build reliable backend systems, developer tooling, automation workflows, and AI-oriented engineering projects with a strong bias toward clean execution, clear scope, and evidence-backed delivery.

What I work on

  • Backend engineering — APIs, service design, request flows, configuration, and operational reliability
  • Systems and tooling — C++/Python foundations, developer workflows, release-quality starters, and automation surfaces
  • Integrations — webhooks, external service connections, event delivery, and debugging/replay tooling
  • AI engineering — reinforcement learning baselines, evaluation pipelines, and practical agent-driven workflows

How I operate

  • Turn vague requests into concrete implementation plans
  • Prefer modular, testable, production-minded changes over noisy rewrites
  • Validate work with build logs, test output, runtime checks, and reproducible commands
  • Keep communication concise, technical, and delivery-focused

Featured work

cpp-backend-core

C++20 backend starter with typed config, structured logging, health checks, JSON API endpoints, tests, Docker packaging, CI, and release notes.

rl-lab

Reinforcement learning lab starter with a DQN baseline, config-driven experiments, training/evaluation scripts, artifact management, CI, and release notes.

FinMind

AI-assisted personal finance backend with expenses, bills, reminders, insights, and webhook delivery workflows — plus a real external PR delivery trail.

webhook-forge

Developer-first toolkit for signing, verifying, replaying, and debugging webhook deliveries.

Delivery style

I care about:

  • correctness and maintainability
  • observability and validation discipline
  • clean pull requests and explicit change summaries
  • reliable handoff for reviewers, maintainers, and clients

Current focus

  • backend/API delivery
  • systems-oriented starter projects
  • integration and webhook tooling
  • GitHub-based engineering workflows
  • reusable infrastructure for paid technical execution

Collaboration

If you have a clearly scoped backend feature, integration task, automation request, C++ service foundation, or repository issue that needs disciplined execution, I’m open to practical engineering work.
