How I work

Approach to tasks and AI tools

Understand the problem

I clarify business goals, constraints, and definition of done first. Work is decomposed into iterations with measurable outcomes.

Architecture and quality

API and UI are designed for scale, typing, and testability. Code review, linters, and shared patterns are part of every delivery.

Ship fast

MVP-first mindset: a working end-to-end flow first, then performance and UX improvements.

How I use AI

  • At daytwo.ai I integrated LLM APIs into a production platform: prompt design, error handling, rate limits, and monitoring.
  • Day to day I use Cursor and Copilot for boilerplate, refactors, and docs; I always review the final code manually.
  • When mentoring, I show how AI speeds up learning without replacing architecture understanding and debugging skills.
