Senior software engineer · Currently at Polygon
Senior full-stack engineer at Polygon. I take products from a blank page to production, then build the tools and agent workflows that make the next one quicker.
Recently: Agglayer UI from concept to production as a near-sole engineer, and the sPOL liquid staking launch. Before that, governance at Aragon and wallet analytics at Cielo across 16+ chains. Outside work: personal agents that remember things, a team picker for our weekly football, and a small pile of CLI tools.
A few things I’ve madePersonal agents & workflows
Voice notes, passing thoughts, things I didn’t want to lose. I built a system around Hermes and Discord that turned everyday conversation into useful memory and follow-ups.
Friends and family still use their personalised setups every day. Mine got overenthusiastic, so I rebuilt it smaller and calmer. There’s a story there.
How it worked, and what I learntFor the weekly kickabout
Picking teams was always a bit of a mess, so I built something to fix it. FairSide weighs ability, fitness, attack, defence and positions, runs 500 shuffles with a greedy swap pass, and picks a formation to suit the squad. Quick mode takes a minute; smart mode goes as deep as you like.
Built for our games. Now 5–10 groups use it regularly.
Pick your teamsBuilt for laughs, shipped properly
Upload a photo, choose roast or glaze, and set the heat from mild to unhinged. Behind the jokes: a lot of model and prompt tuning so all ten modes feel different, plus accounts, credit payments and rate limiting.
A complete product, end to end. Also the most fun I’ve had tuning prompts.
Try a roast (or a glaze)Built for agents, fine for humans
Five small CLIs for live trains, the Tube, Parliament, Companies House and fuel prices. They return clean JSON so agents can use them, and read well enough for people. One skill teaches your agent all five: npx skills add shan8851/agent-skills --skill uk-public-data
Take something useful
Small skills I actually use: a capture, recall and reflect loop for your notes, plus tools for understanding letters, rehearsing hard conversations and stress-testing ideas. Use them as a starting point and make them yours.
Took Agglayer UI from concept to production as a near-sole engineer, then built the sPOL liquid staking launch and the bridge starter new chains build on. Now: backend modernisation, production migrations, and agent workflows for the team.
Shipped token wrapping and delegation for production DAOs, and reusable pieces of the Governance UI Kit and app template.
Helped grow a Telegram bot into a full wallet discovery and analytics app, running across 16+ EVM chains.
Before that: co-founder and CTO at Let’s Eat, then Library of Things and NorthLink Digital.
