Tushar Laad

Data engineer at DoorFeed. Your friendly neighbourhood 0-to-1 engineer.

I take systems from an empty repository to production. Regulatory data, agent platforms and the backends under them by day; a four-product software lab the rest of the time.

London, UK

Nothing starts clean.

No schema, no precedent, no obvious first move. Taking a system from an empty repository to something people depend on is the whole job.

Then it ships.

Treacle went from an empty repository to the Play Store with one engineer across the backend, the app and the infrastructure.

Describe an audio edit in English. It renders.

Drop in your tracks and ask for the mashup you want. An agent plans the operations, the DSP runs locally in Rust, and only the chat goes to the model you pick.

Treacle

A separate company, not part of the lab. I joined as founding engineer and shipped the product alone.

Three screens from Treacle: the weekly match, which delivers one curated person rather than a feed to browse; the assistant opening a profiling conversation; and a voice call running, with the option to schedule one instead

Treacle

Shipped

An AI dating app with no swiping.

Voice profiling instead of forms. You talk, it listens, and it debriefs with you after dates to learn what actually worked. Architected and shipped alone, live on the Play Store.

What people I worked with said

  • Vinay Mehendi, PhDChief Executive, OceanFrogsSenior to Tushar at OceanFrogsSep 2023
    He started as a website developer, took on a data engineer role, built APIs for us. He performed beautifully. When we assigned him his first labelling and machine learning project, he came back not only with a solution but alternative approaches, pros and cons, and all documented well.
  • Joel Joseph JoyAzure and Databricks EngineerManaged Tushar directly at AppsatileMar 2026
    He not only delivered on assigned responsibilities but regularly went beyond expectations, investing additional time to understand underlying systems and improve solution quality.
  • Srujan PProduct and Engineering Manager, OceanFrogsManaged Tushar directly at OceanFrogsSep 2023
    Excellent skills at building data pipelines, REST APIs and Docker. A great team player who communicates effectively and shares knowledge generously.
  • Suleiman Muhammad SaboCybersecurity researcherWorked on the same teamMar 2024
    We were faced with the complex challenge of implementing end-to-end encryption, particularly how to securely store and manage encryption keys. He devised an elegant solution that balanced security with usability: storing public keys on our servers while keeping private keys on users' local devices.
  • Pranjal UpadhyayaSoftware Development EngineerWorked on the same teamNov 2023
    An excellent developer and data engineer with extensive experience in data scraping, data mining, data labelling, data analytics and ML. Very proactive in taking up problems and coming up with novel solutions for them.

Where I have worked

Some of these ran at the same time. That is deliberate rather than a typo: the lab and Treacle were built alongside a full-time job. The bars below sit on one shared axis, so the overlap is visible instead of looking like a mistake.

20202026
Now

Apr 2026 to Present

London, on-site

Data Engineer, DoorFeed

A property investment platform across the UK and France. I build the regulatory data the analysis stands on, the backend that serves it, and the agent that turns it into analyst output.

How the rent-regulation service works
  • Built the regulatory service that answers what rent a property can legally charge, from empty repository to production in 27 days.
  • Sourced the data where no clean feed existed, from public decrees, council mapping services and boundary sets, with every figure traceable to the rule that set it.
  • Built the backend and tool server under the analysis agent, and the valuation logic applying French rent control and English social and affordable rent rules.
  • Own reliability for long-running agent runs: failure detection, recovery, and the telemetry behind both.
