WAYPOINT 01 / ELEV 480M

  • SiteCrew screenshot

    SiteCrew

    In Development

    A two-sided construction labour marketplace for Ireland.

    Workers list free. Clients pay per lead or through a monthly subscription. Built web and Android from a single React/TypeScript/Capacitor codebase. Targeting Dublin first, three trades, with Stripe Connect, GPS check-in, and timesheets in Phase 2.

    React / TypeScript / Capacitor / Node.js / Stripe

  • Lookinit AI Engine

    Production at Speeir

    Multi-provider AI answer engine. Seven LLMs, one gateway.

    Integrated Claude, OpenAI, Groq, Cohere, Mistral, DeepSeek, and Qwen through Portkey. Added LangChain embeddings with Upstash Vector semantic caching at a 0.95 threshold to cut redundant API calls. Built an @mention agent routing system and Vercel AI SDK streaming on a Next.js 14 frontend. 460+ users in production, 95% CSAT.

WAYPOINT 02 / ELEV 1,250M

About

Most engineers either build the system or support it. For the past year, that line didn't exist for me. At Speeir I was shipping production code in the morning and diagnosing user issues in the afternoon. When something broke, the fastest path to a fix was understanding how it was built. That shaped how I work.

I have built an AI answer engine integrating seven different LLM providers through a unified gateway, a multi-tenant fitness SaaS across Go, React, and Flutter, and onboarded 1,200+ users onto a live platform while feeding root-cause findings back into engineering sprints. Right now I am building SiteCrew, a two-sided construction labour marketplace for Ireland.

Based in Athlone, working Dublin-ready. BEng Software Engineering, TUS Athlone 2025. Full work authorisation.
