Get in touchAbout
I'm a senior software developer with over 10 years of experience building backend systems, cloud architectures, and full-stack applications. I specialise in Node.js and AWS — designing scalable, maintainable solutions for companies that care about code quality, test coverage, and real delivery.
Services
Node.js & Backend Development
Design and implementation of high-quality backend systems using Node.js and TypeScript. RESTful APIs, microservices, event-driven architectures — built to scale and easy to maintain.
AWS Cloud Solutions
Architecture and implementation of cloud-native solutions on AWS. Lambda, ECS, DynamoDB, SQS, API Gateway — choosing the right tools for the problem, not just the popular ones.
Full-Stack Development
End-to-end delivery using React on the frontend and Node.js or Java on the backend. Mobile experience with React Native. From prototype to production.
Technical Consulting & Mentoring
Architecture reviews, technology selection, code quality improvement, and hands-on mentoring of development teams. I help teams deliver better software, faster.
AI-Powered Development
AI is part of how I build — from writing code to shipping intelligent features into products.
AI-Assisted Development
Claude (Claude Code, in-IDE and browser) and OpenAI Codex / GitHub Copilot built into my daily workflow — accelerating feature development, refactoring, code review, debugging and test writing.
LLM Integration
Embedding LLM-based features (Claude, OpenAI APIs) into client and internal applications to automate workflows and enhance product functionality.
AI Across the SDLC
Applying AI/LLM tooling throughout the full software lifecycle — requirements analysis, debugging, QA and technical documentation.
Machine Learning & NLP
Background as a Machine Learning Engineer focused on NLP (Python, spaCy), including thesis research on ML algorithms for analysing online user behaviour.
Portfolio
A few personal products I've designed and built end to end.
Freakland
A location-based social PWA where you share "Freaks" with friends or the world, discover and add spots on an interactive map, join Freak Groups, and win prizes through daily shakes and campaigns.

Buzzd
A queue-management system for restaurants and cafés. Customers scan a QR code to follow their order status on their phone instead of waiting at the counter, with mini-games to pass the time and integration with ordering platforms.

Small Business Website Template
A reusable portfolio-site template I use when pitching local businesses — an about section, a project/portfolio gallery, and a simple admin-panel mockup for managing content without touching code.
