Experience

Full Stack Developer · Melt Studio

Jun 2022 – Present

Maintenance & field-service platform (Dec 2024 – present)

Deliver features across a Vue 3/Nuxt web app, a NestJS API (CQRS, event sourcing, MongoDB, Redis + Bull) and an offline-first Flutter app used by field technicians across 12+ organizations.
780+ merge requests merged across all Melt projects and 300+ approvals of teammates' work; built a senior-level AI code-review agent that drafts verified findings as inline GitLab comments.
Built an AI-assistant integration that fills out job forms from what a technician types or dictates, routing every write through CQRS commands with user confirmation and site-scoped permissions.
Led the outage-management module from scoping to release (web register, offline sync, branded emails, legacy-data migrations), plus invoicing improvements.
Shipped 15+ mobile releases through Codemagic and got builds back under the 60-minute limit by trimming a 5.46 GB cache below the 3 GB cap.

Operations-log product, took ownership (Feb 2025 – Apr 2026)

Authored about 70% of the merged MRs on a Next.js + MongoDB operations-log product: shift turnover, check-in/out, audit history, multi-site timezones and SendGrid reports on AWS Lambda.

Earlier work (2022 – 2024)

Returns product (2022 – 2023, 230+ merged MRs): scheduled functions that parsed purchase emails into orders, items and totals, plus React Native/Expo flows and a React admin panel.
AI work (2023 – 2024): survey components feeding an AI activity matcher, and an internal chatbot with a Shopify integration.
