Single-handedly migrated a global security-technology manufacturer's US website — 8,000 pages and 70,000 registered user accounts — from a legacy, end-of-life Drupal 7 platform to Adobe Experience Manager (AEM), over 10 months, end to end. What I did: • Migrated 8,000 pages into AEM's component-based authoring model • Exported and re-imported 70,000 registered user accounts with zero data loss • Rebuilt the site's search and analytics systems • Designed and executed a full URL redirect map to preserve SEO equity across thousands of legacy URLs • Delivered global content faster via CDN, and made day-to-day content updates manageable for non-technical teams Results: • +20% traffic in the first month post-launch — roughly +160,000 monthly unique visitors • 300% increase in sales inquiries • Lower maintenance overhead, easier content operations How I'd do it today: Since this project, I've moved into AI-assisted engineering. On a migration like this now, I'd compress the timeline with LLM-assisted content mapping and cleanup, semantic (embedding-based) URL matching to auto-generate redirect maps instead of mapping thousands by hand, automated QA to diff migrated pages against originals, and a modern vector/semantic search in place of legacy keyword search. Same enterprise rigor — delivered faster.

Over the years, I’ve worked with both startups and enterprises to turn complex ideas into reliable, production-ready platforms. My focus is on creating backend architectures that are efficient, maintainable, and built for long-term growth. • Tools I can use when delivering your project ✍🏻 Programming Languages: Java, Python, C++, JavaScript, Dart 🛠️ Backend Frameworks: Spring boot, JakartaEE, Django, FastAPI, Flask 🎨 Frontend Frameworks: React JS, Next JS, Flutter 🛢 Database Management & Cache: MySQL, Supabase, PostgreSQL, MongoDB, SQLite, Redis 🗃️ Event Streaming: Kafka, RabbitMQ 🛡️ Security & Secrets Management: KeyCloak, JWT, HashiCorp ⚙️Automation Management & BPMN: Camunda, N8N 📊 Observability: Grafana, Loki, Kibana, Prometheus 🏗️ System Architectures: Monolithic, MVC, Microservices, Event-driven • Key Highlights - At Crewpr, a Dubai-based startup available on the App Store and Google Play, I served as the first backend engineer. I designed and launched the platform’s entire backend, from architecture to production, delivering a reliable MVP that now serves over 500 active users. - I contributed to Yugo, a large-scale student accommodation platform serving users across Europe, where I enhanced scalability, optimized backend performance, and ensured smooth multi-region operations. - I also collaborated on several governmental digital transformation projects in Ireland, including Enterprise Ireland, NEH, and Startup Ireland, delivering secure, stable, and scalable backend systems that support thousands of daily users. ✨ I believe in clarity, precision, and engineering excellence. Every system I build follows clean architecture principles as OO, SOLID and Design patterns.
