Full‑Stack Development

• Led the software development of a GIS map application, driving revenue growth by 10x and positioning the product as a primary data asset.
• Directed full‑stack GIS map development, overseeing PostgreSQL, Mapbox, ReactJS, and NodeJS to deliver an integrated solution.
• Led the development, deployment, and support of over 30 GIS projects, demonstrating expertise in PostgreSQL, Bash, Python, JavaScript, GDAL, ArcGIS, PostGIS, and Mapbox technologies.
• Developed 100 web applications using HTML/HTML5, CSS/SCSS, Django, WordPress, and Joomla frameworks, ensuring diverse online presence.
• Architected, developed, implemented, supported infrastructure, data processing, and the map application for 2 years non‑stop without any weekends, holidays, or vacations, 10–14 hours a day.
• Architected a layered maritime platform separating a Next.js PWA frontend, a Go (Huma/Fiber) API, and a PostgreSQL function layer, keeping all business logic in the database.
• Designed an organization context‑switching system with client localStorage and server‑side cookie mirroring, letting users act as managed organizations while enforcing least‑privilege authorization.
• Built the Next.js 16 frontend with deliberate SSR, SSG and CSR strategies, and a reusable prefetched‑server‑page factory that removes the N+1 fetch cascade from each authenticated page moved onto it.
• Delivered full Progressive Web App support — installable and offline‑capable — with Workbox runtime caching via next‑pwa.
• Established an English/Danish internationalization system carrying 12,027 messages per locale across 458 namespace files, with linter‑enforced vocabulary and a 400‑line budget per file.
• Set the platform's founding decisions in the weeks after the repository opened in November 2025 — the layering, database‑first data access and the zero‑warnings bar — and they still hold nine months on.
• Developed and maintained Django web applications for the IPTV platform, shipping new features and improving performance and stability.
• Maintained and enhanced the legacy Hugo static‑site website while contributing UI/UX improvements to the primary asset‑management product.
• Built the operator back‑office — around 40 admin routes and 128 components covering claims, moderation, feature flags, cache and diagnostics — so the platform can be run without database access.
• Built company ownership claims end to end — a user claims a company, an administrator adjudicates, and an approval rewrites the authorization graph that decides who is allowed to edit what.
• Built the platform's social layer — posts, feed, groups, mentions, a follower graph and an occasions digest — on the same function‑first data layer as the rest of the product.
• Built the hiring marketplace and the seafarer career workspace — 151 stored functions across 48 tables — covering vacancies, applications, certificates, rank progression and verified sea time.
• Built a multilingual static site in Hugo across 104 template files including 49 partials, publishing every page in four representations from one content tree in three languages.
• Built a database‑driven CV, references, portfolio and cover‑letter generator in Python — 41 modules, 10,580 lines — rendering six output formats from one 23‑table SQLite source assembled by a 19‑step idempotent pipeline.
• Built a native macOS messaging client in Swift 6 and SwiftUI — 11,141 lines across 53 files — over the C interface of a Rust core linked as a static archive from a pinned revision.
