Full-stack engineer who spent nine years in manufacturing process/R&D watching production data live and die in unversioned Excel files, then retrained to build the systems that should have existed. Part-time at Downshift by design; looking for a full-time role, available now.
- At Downshift (TypeScript/NestJS/React Native): wiring iOS home-screen widgets to live data, and reworking dashboard drag-and-drop to commit once on drop instead of calling the API on every move.
- Replaced a legacy Excel dataset with a Rails 8 + PostgreSQL app — schema design, data migration, and real-time dashboards in place of manual reports.
- Shipped Gemini-backed pipelines for automated i18n across 3 locales and structured extraction of medical data from uploaded images.
- Built auth from scratch in Rails, including OmniAuth for Google, GitHub, and LINE.
I spent nine years as a process and R&D engineer in materials manufacturing, watching critical production data live and die in unversioned Excel files. I retrained as a software engineer to build the systems that should have existed. Currently full-stack at Downshift (part-time, TypeScript/NestJS/React Native) — part-time by design, so I'm free to move full-time. Available from October.
- Replaced a legacy Excel-based dataset with a Rails 8 + PostgreSQL application — schema design, data migration, and real-time dashboards replacing manual report assembly.
- Shipped Gemini-backed pipelines for two production problems: automated i18n across 3 locales, and structured extraction of medical data from uploaded images.
- Built auth from scratch, including OmniAuth for Google, GitHub, and LINE.
I am a Software Engineer with 5 years of experience building secure, maintainable, and data-driven web applications. I specialize in full-stack architecture, migrating complex legacy processes (like unmanaged Excel data) into modern relational PostgreSQL schemas, and integrating AI workflows.
Highlights:
- Architected a Rails 8 application migrating legacy Excel datasets into PostgreSQL with real-time visualizations.
- Integrated Gemini AI to automate i18n tasks and extract medical data from uploaded images.
- Implemented robust authentication systems including OmniAuth integration for Google, GitHub, and LINE.
