Portfolio
What we do — and the work that proves it.
Software Engineering
Platform & Solution Architecture
- As one of the first hires, designed and built the entire core infrastructure and supporting processes from scratch for a green‑energy SaaS startup, laying the foundation for rapid growth.
- Planned and implemented new infrastructure functionality for internal and external systems, building solutions durable enough to still run years later with minimal change.
- Architected and implemented the platform end to end — backend, database, frontend, design system, infrastructure and security — establishing the technical foundation and engineering standards.
- Modeled the maritime domain — professionals, companies, ships, jobs and reviews — into normalized PostgreSQL schemas with SMALLINT lookups and UUID v7 keys.
- Designed a PostgreSQL function‑first data layer across the platform's domain schemas (identity, organization, review, message, notification and more), exposing all data access through stored functions.
- Migrated the HTTP API from Fiber to Huma v2, gaining automatic request validation and OpenAPI modeling across all endpoints.
- 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.
- Designed a JSON passthrough architecture where PostgreSQL functions return complete JSON forwarded verbatim by the Go API, eliminating intermediate unmarshalling and decoupling the frontend from schema changes.
- 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.
- Optimized budget costs 10 times with zero loss in productivity for the Saudi Arabia company by reimagining the overall infrastructure, eliminating unnecessary services, and relocating from the AWS cloud.
- 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.
- Overhauled internal processes, saving 8,000 hours by improving software architecture, systems, and scheduling efficiency.
- Led the software development of a GIS map application, driving revenue growth by 10x and positioning the product as a primary data asset.
- Designed a comprehensive infrastructure framework for DTU impacting 14 departments, featuring flexible modules, unified data pipelines, and structured support strategies for long‑term adoption.
Software Engineering
Backend & API Development
- Developed and maintained Django web applications for the IPTV platform, shipping new features and improving performance and stability.

- Built a Python vessel‑data scraper (MarineTraffic, Maritime‑Database) and imported roughly 700 maritime companies to seed the platform's core reference data.
- Implemented a catalogue‑driven deep‑merge for stored JSON preferences, preventing missing‑key crashes as the schema evolves.
- Implemented startup mail‑provider validation across three providers (SendGrid, SMTP2GO, Azure ACS) with environment‑aware behaviour — logging in development, failing the boot in staging and production.
- Built a request‑schema validation contract with automated guards that catch frontend/backend payload mismatches before they reach production.
- Developed a Data Analytics reporting system, increasing quarterly software revenue by 400% through Python‑based PDF reports.

Frontend Development
- Maintained and enhanced the legacy Hugo static‑site website while contributing UI/UX improvements to the primary asset‑management product.

- Delivered full Progressive Web App support — installable and offline‑capable — with Workbox runtime caching via next‑pwa.
- Built the Next.js 16 frontend with SSR, SSG and CSR strategies and a server‑shell prefetch‑and‑hydrate pattern that eliminated N+1 fetches.
- Designed 30 websites, delivering unique and flexible solutions by converting Photoshop designs to HTML.
- Developed 100 web applications using HTML/HTML5, CSS/SCSS, Django, WordPress, and Joomla frameworks, ensuring diverse online presence.
- Contributed to user interface design processes, ensuring intuitive, visually appealing, and user‑friendly project interfaces.
