About

The short version.

I like taking hard product problems and making them feel simple. I work across web, mobile, backend, cloud, and AI. From the first question to the final release, I stay close to the work and make sure every choice has a reason.

How I work with AI

A clear process, not blind trust.

AI helps me explore ideas and build faster. I still choose the direction, review the work, and take responsibility for the result.

  1. 01

    Understand

    Learn the product, read the code, and understand the users, limits, and things that could go wrong.

  2. 02

    Question

    Ask AI for different ways to solve the problem, including the good and bad sides of each one.

  3. 03

    Cross-check

    Compare the AI answer with the code, product needs, and what I know from experience.

  4. 04

    Plan

    Break the work into clear steps and decide how I will know when each step is done.

  5. 05

    Direct

    Give AI the right information, clear limits, and a clear task.

  6. 06

    Verify

    Review the work, run tests, check security and unusual cases, and fix anything that is wrong.

The goal is not to create more code. It is to build faster while keeping the work clear, correct, and safe.

Full-Stack Build

ChalkLens.

Offline lesson kits for teachers, powered by local Gemma 4 inference. A Flutter desktop app that turns textbook PDFs and scanned pages into classroom-ready lessons — explanations, teaching notes, quizzes, activities, and homework — without ever touching the cloud. Built for the reality that most classrooms can't depend on reliable internet, with a Present mode for laptop-based teaching and a Student Help flow grounded in lesson context.

Full-Stack AI Build

TalkPatch.

A self-directed demo for configuring AI phone agents across inbound and outbound call workflows. I built the product experience for defining agent behavior, opening lines, voice settings, and business-specific guardrails, then used it to demonstrate a dental receptionist flow for appointment requests, urgent-call triage, and human handoff.

Nucleus AI.

An AI-agnostic knowledge infrastructure platform — your second brain for work. Nucleus ingests documents, Gmail, Drive, and links into a single source of truth that any AI tool can query via MCP, returning natural-language answers with source citations and no folder overhead. I ship across the Next.js product surface, the API layer, and the retrieval model that makes unified search fast and grounded.
