Daniel Rosales
Freelance Product Engineer
I translate business rules, controls, and workflows into maintainable enterprise software.
| Focus | Outcome |
|---|---|
| Custom enterprise systems | Business processes translated into clear, dependable software. |
| Rules, controls, and workflows | Day-to-day operations that are easier to run, understand, and evolve. |
| Current work | An anonymized custom operational system with billing and business controls. |
I work with teams that need complex operational logic made practical. The foundation is readable code, thoughtful architecture, and deliberate review.
I am an active member of Gentleman Programming, collaborating through code, reviews, and triage.
- Gentle AI and Engram are open-source projects with 5k+ GitHub stars each.
- OpenCode supports my planning, implementation, and review workflow.
AI supports the process; engineering judgment and fundamentals remain essential.
- Gentle AI PR #1588: Added a Windows-safe file and stdin handoff for review artifacts, avoiding fragile PowerShell JSON quoting while enforcing bounded, regular-file inputs.
- Gentle AI PR #1587: Tightened correction and replay boundaries in the review workflow, preventing unsupported retries while preserving compatibility with existing records.
- Gentle AI PR #1415: Made Git Bash discovery deterministic across common Git for Windows layouts, so the tooling avoids unintended WSL fallbacks and runs more predictably.
- Clear architecture that makes systems easier to understand and evolve.
- Maintainability through simple design, readable code, and deliberate review.
- Continuous learning grounded in hands-on practice.
- Practical products that solve real needs.
