Jeremy H.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Jul 23, 2026.

I help small to mid-sized businesses and studios turn ideas into reliable software fast. I’ve shipped mobile apps, VST/AU audio plugins (JUCE/C++), marketing sites, custom web apps, desktop utilities, embedded/DSP projects, and production game/VR/XR work. A big part of my workflow today is agentic AI: I actively use tools like OpenAI ChatGPT / Codex, ClaudeCode / OpenClaw-style agent runners / Copilot-class assistants to accelerate research, implementation, refactors, test generation, documentation, and code review. I accomplish all of this while keeping human-level engineering judgment in the loop. The result is faster iteration without sacrificing maintainability, performance, or correctness. On the VR/XR side, I build Quest/OpenXR/SteamVR experiences with attention to frame-rate targets, interaction design, and platform specifics. I’m comfortable owning gameplay systems, UI/UX flows, tools, and integrations (telemetry, auth, analytics, payments). What clients notice first is how I operate: calm, direct, and easy to work with. I explain trade-offs in plain language, give clear plans, and provide frequent updates. There is no drama, just steady progress. How I work -AI-accelerated, engineering-grounded: agentic workflows + disciplined code review and testing -Fast & accurate: practical tests, CI when appropriate, and systematic debugging -Efficient: prioritize impact, reuse proven patterns, keep docs lean but useful -Versatile: own features end-to-end or plug into your team/process immediately Technical snapshot -Languages/Frameworks: C/C++ (JUCE), C#, Python, JavaScript/TypeScript (React/Next.js, Node), PHP -AI/Agents: OpenAI API, agentic coding workflows (task decomposition, tool use, evals) -Platforms: web, mobile, desktop, embedded, games/XR (Unity, Unreal) -Data/APIs: REST/GraphQL, SQL/NoSQL, auth/integrations -Build/Ops: Git, CI/CD, containers, cloud fundamentals -Quality: logging, profiling, error handling, performance tuning, maintainable architecture Typical engagements -AI integration + “agentic enablement” for teams -MVPs, internal tools, dashboards -XR prototypes and production features (Unity/Unreal, Quest/OpenXR) -Refactors, performance tuning, reliability hardening -A senior “force multiplier” to accelerate a backlog If you need a calm senior engineer who ships quickly, precisely, and communicates clearly, I’m a strong fit.
