About me

I am a Full-Stack Software Engineer with 5+ years of experience designing and delivering scalable, high-performance web applications using Ruby on Rails, Node.js, React, PostgreSQL, AWS, and modern DevOps practices.

My background includes building applications used by 500K+ users, optimising system performance, designing secure REST APIs, and leading engineering teams with Agile Scrum delivery.

I’m currently based in the UK and pursuing an MSc in Programme & Project Management, adding strong project delivery, leadership, and stakeholder management skills to my technical experience. This allows me to bridge engineering and business needs, making me effective in both Software Engineering and Tech Project/Delivery roles.

💡 **Key Achievements**
- Built and optimised APIs serving 500K+ active users
- Improved backend performance by 30% through database query optimisation
- Implemented CI/CD pipelines (GitLab/Jenkins), cutting deployment time by 40%
- Developed high-quality test automation (RSpec, Capybara) with 90%+ coverage
- Led and mentored a team of developers, improving code quality and delivery consistency
- Delivered features across multiple product domains (SaaS, healthcare, education, enterprise apps)

🎯 **What I’m Looking For (UK)**
I’m open to:
- Software Engineer / Full-Stack Engineer roles
- Backend Engineer (Rails/Node)
- Technical Project Manager / Delivery Manager
- Technical Consultant roles
