I build low-level stuff from scratch: RISC-V, emulators, boot paths, and game tech.
I also ship backend + web systems (APIs, integrations, infra, observability).

• Ex-Nihilo Core: a RV32 RISC-V emulator in portable C (C17)
  • Boots a Linux kernel (OpenSBI + DTB + kernel image)
  • Passing official ISA tests and tightening spec correctness (CSR/traps/priv flow)
• Long-term goal: my own RISC-V CPU on FPGA, and eventually Linux on real hardware
• R&D on my game project:
  • Top-down 2D RPG / sandbox ideas
  • Engine work in C (SDL2 + OpenGL), performance-first rendering, deterministic simulation mindset

• Repo: https://github.com/Project-Ex-Nihilo/Ex-Nihilo-Core
• Focus:
  • Portable + readable systems code
  • Windows (MSVC) + Linux support
  • Realistic boot flow (OpenSBI / DTB / Linux)

• Systems / low-level: emulation, debugging, tooling, boot flows, portable C
• Backend / web: APIs, integrations, data flows, cloud infra, reliability + observability

Backend / web

• Node.js (TypeScript/JavaScript), Express-style APIs
• Ruby on Rails (maintenance + features)
• .NET (ERP maintenance / integration)
• Prisma ORM, Swagger, PM2

Cloud / infra (AWS)

• Lambda, EC2, ECS, S3, SQS, RDS
• DynamoDB + Redis when it makes sense
• Message-driven systems (SQS / RabbitMQ)

Observability

• Grafana + CloudWatch (metrics, monitoring, debugging in production)

Security (practical)

• OAuth2 basics, OWASP mindset

Languages

• C/C++, Python, TypeScript/JavaScript, Ruby
• Also: C#, Java

Hardware / embedded side

• Arduino, Raspberry Pi, FPGA, RISC-V / microcontrollers

• I document everything I can (because future-me is a stranger)
• I prefer simple, direct writing and step-by-step correctness
• I care more about “does it really work?” than “does it look cool?”

• If you want to talk or collaborate: open an issue or discussion on a repo.
• PRs are welcome when they improve clarity, correctness, or portability.
