Senior Software Engineer · AI Agentic Engineering

Engineer first.
AI-accelerated.

I'm Aira Astilla, a Senior Software Engineer with 7+ years shipping web apps and mobile apps. Today I lead a team of AI agents, and I review every line they write.

// 01 — the difference

Anyone can prompt an app. Shipping one that lasts takes an engineer.

AI agents make me faster. Seven years of engineering decides what they build, catches what they miss, and keeps it running after launch.

Criteria
Software engineer + AI agents
Vibe coding, no engineering background
Architecture
Designs the data model, APIs and boundaries first, then hands agents a spec.
Lets the model pick the structure, so patterns drift with every prompt.
Code review
Reads and reviews every change before it merges.
Ships output it can't fully read or explain.
Production bugs
Traces the root cause through UI, API and database, and fixes it once.
Re-prompts until the error message goes away.
Legacy systems
Migrates real codebases with parity: business rules preserved, screen by screen.
Starts over from scratch and quietly loses the rules nobody wrote down.
Security & data
Has built for government and healthcare, where auth and data handling are non-negotiable.
Leaves secrets, permissions and personal data to whatever the model suggested.
After launch
Spec-driven and documented, so the next developer can extend it.
Works on demo day, then gets harder to change with every fix.

An agentic workflow with a human in charge

  1. 0101 / spec

    Plan before prompting

    Requirements, architecture and acceptance criteria go into a spec the agents follow.Architecture and acceptance criteria go into a spec the agents follow.

    Claude Code and OpenAI Codex agents work in parallel on scoped tasks.

  3. 0303 / integrate

    Model Context Protocol connects agents to the real tools and data the project needs.Agents reach the real tools and data the project needs.

  4. 0404 / review

    Human review, always
