Mukul Malik

Applied AI engineer in London. Founding member of Tesco Mobile's first AI team.

I find where AI can change how a team works, build the agent system, measure whether it worked and get it adopted. On my own, I build PAI Mentor, an AI tutor that runs on Claude Managed Agents. Three years of regulator reporting mean I build AI that holds up when someone checks it.

Selected work

  • Finopedia: a knowledge base that an AI keeps up to date

    Tesco Mobile · 2026

    Knowledge about a regulated finance codebase was spread over code, wiki pages, PDFs and people's heads. An AI agent now turns all of it into one knowledge base, where every claim points to its source. A new joiner made his first contribution in 2 weeks instead of 6–8.

    The pattern is open source as agent-wiki. I presented it to Tesco Group at Data Mashup 2026, and now lead the proposal to give every Tesco Mobile team its own.

  • Revenue questions in plain English, measured

    Tesco Mobile AI team · 2026 · its first proof of concept

    The team wanted to know if business users could ask revenue questions without SQL. I built it on Databricks Genie and tested it on 20 real questions from the analyst's own work, reaching 85%+ correct. I wrote up what worked as tested rules, so the next project starts from evidence.

  • Customer feedback, sorted in a week

    Tesco Mobile AI team · 2026 · a prototype I proposed

    It sorts 3,600+ customer reviews and social posts by topic, tone and outcome, and sends the ones that need a person to a person. The social media team saw it and asked for help with replies, so I built a queue where a person approves every reply.

  • PAI Mentor: an AI tutor I build and run alone

    Own product · since 2025 · private beta

    For candidates preparing for India's civil-service exams. I rebuilt the tutor on Claude Managed Agents in five days when the first design cost more than it gave back. A chain of AI agents reads a student's answer sheet, checks the facts, scores it and gives feedback, and I tested the reader on 1,100 questions before it shipped.

  • joinqa: a live Q&A app, built in three days

    Own build · 2026 · joinqa.pages.dev

    Audience questions and polls from a QR code. I tested it with 1,000 simulated phones, then Tesco's Head of Data Science ran his own panel on it with 88 people live.
