Software engineer with an eye for design. I build full-stack apps

Two years of industry experience across backend services, data pipelines, and full-stack web and mobile apps, plus a shelf of shipped side projects with real users. I sweat the details in both my code and my interfaces, because I’m an artist when I’m not an engineer (and usually both at once).

Things I’ve made

Products I design, build, ship, and support end-to-end, with a growing user base and real feedback loops.

Featured · SaaS for artists

Paletto

Full-stack SaaS for artists to manage commissions, projects, inventory, and finances. Built web-first with Next.js and Supabase, alongside a cross-platform Expo mobile app. Designed in Figma across web and iOS so it never gets in the way of the creative process. Iterated on the dashboard and navigation from early user feedback, simplifying the hierarchy so logging a session or tracking a commission takes fewer taps. Grown from zero to ~32 monthly users.

Aera

iOS · on the App Store

Most breathing apps are too complicated to use mid-panic-attack. I designed Aera in Figma around one principle: radical simplicity. Every decision came back to one question: would someone in a panic actually use this without becoming more stressed?

iOS · on the App Store

A personal hydration companion with a different paradigm: it guides users on their hydration needs throughout the day, instead of making them log every single glass of water like a chore.

Period apps assume a textbook 28-day cycle, putting everyone in the same cluster. Rue is a period tracker that tells you what’s normal for you, not a statistical average. It allows logging of symptoms, mood, sleep, and flow&mdash, so you can be free from stress of wondering if your cycle is normal.

Research & Developer Tools

Shipyard

A native macOS menu-bar app that finds every open pull request you've authored across GitHub and collapses each one's CI checks into four buckets: failed, passed, queued, skipped. Star one PR and its live counts sit right in the menu bar. Tickets track work before a PR exists, then offer to link themselves once a matching branch shows up. Signed, notarized, and quiet: it refreshes faster while tests run and backs off when you're away.

Hublands

An open-source interactive atlas of the Hugging Face Hub. Maps models and datasets as a browsable survey chart where position encodes semantic similarity. An offline Github Actions pipeline fetches and embeds every repo. The browser renders the GPU points with deck.gl. Born from aiding researchers to see the shape of the Hub instead of searching for names you already know.

Spool

A native macOS menu-bar app, built collaboratively, that turns rough idea dumps into structured markdown. Everything runs on-device against a local OpenAI-compatible model server, spun up only when a document is queued and evicted from memory once the work is done. Drafts arrive by file picker or a watched folder. Ships as a single SPM executable and fully open-source.

Sift

A macOS/Linux menu-bar app with 12 active users that fetches and summarizes ArXiv papers using on-device transformer models and a local NLP pipeline for semantic grouping and ranking. Iteratively improved from real researcher feedback.

API Latency Monitor

A Python CLI tool published on PyPI that monitors HTTP endpoints for latency degradation, with full test coverage across the HTTP engine, database layer, and formatter. Sends Telegram notifications on important degradation events. Born from wanting a simple, zero-config way to track endpoint health without standing up Prometheus, Grafana, or a full APM stack.

Where I’ve worked

Software Engineer · Lumion

Sep 2026 – present
  • Owned Lumion's Skills feature end-to-end and shipped it in under 2 weeks, letting schools schedule recurring reports that the company's AI assistant runs automatically, with results verified against source data, PII scrubbing, and email, SMS, and in-app delivery.
  • Discovered that PR CI was silently skipping ~10,600 tests (16% of the suite) and rebuilt test sharding around recorded run times, cutting PR test runs from 30+ to about 20 minutes while running every test.
  • Built AI evaluations for the assistant, including regression test sets and multi-turn prompt A/B testing, catching invented product features and fixing refusals to answer "what should I do next?" for 27 of 114 schools.
  • Expanded what the AI assistant can answer and do by closing 12 capability gaps with 10 new MCP tools across tasks, messages, appointments, payouts, and surveys, plus confirmable contact actions.

Independent Developer · Self-employed

Jan 2026 – present
  • Design, build, ship, and support a portfolio of 5 consumer and SaaS products end-to-end, from concept and careful UI design through production releases, analytics, and ongoing user support (alongside full-time employment).
  • Shipped 4 iOS apps to the App Store plus open-source macOS developer tools; the first 2 apps reached 172 downloads and 70 monthly active users in their first month, with a 5-star average rating.
  • Built Paletto, a full-stack commission-management SaaS for artists, web-first with Next.js and Supabase plus a cross-platform Expo mobile app (under development), taking it from zero to ~32 monthly users.
