10+ years building backend systems. Now shipping LLM features in production.
Open to Lead / Senior Backend roles - UK remote or West Midlands. Laravel, AWS and applied AI.
<About Me/>
Lead Backend Developer with 10+ years of professional experience in backend architecture, cloud infrastructure, and scalable web applications.
Currently Lead Backend Developer at Sociuu ApS (Denmark), leading a team of six and owning backend architecture alongside the CTO on a SaaS employee advocacy platform used by enterprise clients.
I design and ship the platform's LLM features - OpenAI-powered content generation built into the Laravel codebase, along with the prompt engineering, variant flows and token accounting behind them. Day to day I build with agentic tooling (Claude Code, Copilot, Cursor) and review its output as closely as any other code.
MSc Data Science & Analytics (Distinction) from the University of Hertfordshire, where my dissertation put a machine-learning prediction API into that same live platform. Four of my pull requests are merged into GitHub's Spec Kit.

AI & LLM Engineering
Shipping LLM-powered features into a live SaaS product, not experimenting on the side.
LLM Features in Production
Design and direct the OpenAI-powered features inside the Sociuu platform, working hands-on in the Laravel codebase alongside the backend team.
- ▹AI content generation for email subject lines, preview and preheader text, suggested share messages, titles and descriptions
- ▹Content classification, plus token and cost accounting per request
- ▹Generate, preview, accept or regenerate variant flow so editors stay in control of what ships
- ▹Authored the AI action classes behind subject and preview generation, accept-variant and regenerate
Applied Prompt Engineering
Wrote and tuned the prompts behind those features - the part that decides whether generated copy is usable or noise.
- ▹System prompts and persona/role instructions written against real product copy
- ▹Temperature and max-token tuning per action, balancing output quality against cost
- ▹Prompt changes reviewed like code, since a prompt edit is a behaviour change
AI-Assisted Development
Agentic coding tools daily, with the senior half of the job being review - catching hallucinations and holding output to Laravel and SOLID conventions.
- ▹Claude Code as the primary driver, with GitHub Copilot and Cursor alongside
- ▹Built custom Claude Code skills for the team’s recurring workflows
- ▹Uses MCP (Model Context Protocol) servers and orchestrates background agents
- ▹Reviews and audits AI output before it reaches a merge request
Spec-Driven Development
Specs before code, so AI-assisted work stays anchored to intent rather than drifting.
- ▹GitHub Spec Kit, OpenSpec and Intent by Augment Code used on real feature work
- ▹Plans written and reviewed up front, then implemented against the spec
