Mailens MCP server

Lens of Empires
An Age of Empires-style RTS where the Lens community are the units. Villagers call you “Boss”, community PFPs show up as kings, and there are orcs, monks and dragons. Built in a day, then kept growing: multiplayer, smarter AI enemy, new buildings. Desktop only, free, no login.
@rewinder on Lens
Facebook Memories, but on Lens. A daily bot that quotes what you posted on this day in past years and tags you. Costs $0 to run, so it stays on forever.
Affinity Circle, open sourced
The circles from Lensie — the section that maps who you actually interact with on Lens — are now open source. Someone asked for it, so I pulled it out into its own repo: use it, fork it, break it, improve it. It's all yours.
Lens Starter Packs on AskLC
AI-curated follow packs for Lens, built from recent network activity and grouped by category — so new people have someone to follow on day one.

From bedroom uploads to AI-amplified.
Old YouTube uploads
Bedroom takes
Years ago I uploaded covers, song attempts and random musical experiments to YouTube — just me, a guitar and a webcam. The pre-AI era.
AI-made songs on 0xFM
Lots of songs made with Suno — wrapped raps, language-learning songs, genre experiments, product jingles, tributes. All live on 0xFM.
Things I keep saying.
In one day I can do what it used to take me one month. Cloud Code is the first tool that made me feel limitless.
Helping someone else is the best high I know: adrenaline, confidence, purpose, and real connection, all at once.
Constraints create creativity
Asking for help is not giving up. Asking for help is refusing to give up.
AI stands for Amplified Imagination.

Looking for a team.
A place where I can contribute, learn,
and help others do the same.
I'm open to full-time, contract, or founding-engineer roles. Especially excited about teams building AI-native products, developer tools, or consumer social. Remote-first from Madrid, open to relocating.
