The black cat developer: building serious systems without taking the README too seriously.
I design and evolve backend platforms, developer tooling, MCP servers, and agentic systems. I care about explicit boundaries, observable behavior, operational simplicity, and software that remains understandable after the first successful release.

A self-taught path from BASIC to production systems in TypeScript, Go, Python, Rust, Elixir, Java, and C++. Today, the work is centered on scalable backends, AI integration, cloud platforms, and tools that help other developers move with more confidence.
|
Senior Software Developer |
Backend architecture for healthcare technology, MCP and agent integrations, cloud platforms, and developer experience. The focus is dependable systems, clear domain boundaries, and automation that supports—not replaces—engineering judgment. |
|
Senior Software Developer |
Cloud migrations, multi-region workloads, internal agentic tooling, backend modernization, and production operations across AWS-based environments. |
|
Backend Developer |
Backend services, APIs, CLI tooling, data infrastructure, and the modernization of systems used at large scale. This period established the foundation for my work in distributed systems and developer tooling. |
|
Services, APIs, workers, and distributed systems |
Infrastructure that can be operated with confidence |
Persistence, caching, search, and asynchronous workflows |
|
Enough frontend to deliver complete products |
Feedback loops, collaboration, and automation |
|
|
High-performance code agent with a PTY-backed shell, surgical file operations, and semantic code navigation. |
Multi-platform streaming platform focused on fast startup, resilient playback, and a consistent experience across browsers and devices. |
|
Gleam/OTP research project exploring persistent digital agents, memory, emotion, and emergent behavior. |
Compatibility gateway connecting Claude Code-style clients to OpenAI-compatible providers and local models. |
|
ESP32 composite-video generator and CRT lab toolkit for NTSC/PAL calibration, test patterns, and remote monitoring. |
Reusable AdonisJS application kit focused on clean architecture, production-minded defaults, and developer experience. |
