notes on putting AI into real work

Robotics engineerby training.Product engineerby trade.I put AI intoreal workflows.

First product engineer at a VC-backed proptech · 200-member community · 10+ events

I build full-stack products from zero to one and stay close to the people who use them. Most recently I built the tenant portal at Theo (then hallo theo), a Berlin proptech backed by Insight Partners, from scratch across React, Python, and Google Cloud.

Master's in robotics from KIT. German C1, English, Chinese. Based in Berlin, open to AI and product engineering roles, and to fixed-scope projects for small teams in the US and Europe.

The longer story

02 built

  • 01

    FlowMeet

    MVP, not launched

    Matching and flow management for in-person events. The evening runs as a state machine (check-in, matching, feedback) with realtime sync, so the host sees the room instead of guessing.

    Next.js, Supabase. Matching is interest-based for now. No external customers yet.

    A job-application agent that stays on your laptop

    Prototype

    Scores job postings against your background, drafts applications, tracks status. It runs in your own browser and keeps your CV on your machine, not on a server.

    Built because I needed it.

  • 03

    My own work system

    In daily use

    An Obsidian vault plus Claude Code agents wired to email, calendar, and job search through MCP. Delegated tasks come back finished, with what was skipped and what needs my decision.

    What I write about AI at work comes from running this.

written up, not built

  • DuWo · An AI reading of your own notes and journals: a psychological mirror, not a productivity score.
  • Klarblick · One financial overview for people in Germany whose money sits across several banks, currencies, and countries.
  • PainRadar · A newsletter that turns Reddit noise into a ranked list of problems worth building for.

03 for hire

  • 01

    AI workflow automation

    Pick one task your team repeats every week. I automate it, test it on your real data, and hand it over with setup notes and a walkthrough.

  • 02

    Python backends and data pipelines

    API integrations and databases that stay clean: proper constraints, deduplication, and writes that are safe to repeat. Includes sensor and video data for robotics and vision teams.

Every project starts with a written scope that says what is included and what is not. Fixed price, paid before work starts. Delivery ends the project; later changes are a new agreement. My working hours overlap US East Coast mornings.

  • Entrohub: a community of 200 international founders, engineers, and operators in Germany. 10+ events, a 10-person volunteer team, community operations run by agents.

    Paused in August 2026. No revenue model was in place.

  • Career consulting for people job-hunting in Germany, run as 阿立聊offer: 32 paying clients in 2025, delivered by one person with an AI-assisted pipeline that cut time per session by 30%.

    A service business, not a product. It proved people pay for judgment.

  • What it taught me: distribution is the hard part, more than the engineering. I now build things only after I can name the person who will use them.
