Recursive Trail

Two engineers. One trail.

Recursive Trail

Learn. Build. Experiment. Repeat.

We're a two-person team messing with projects, random experiments, and whatever we want to understand next. We write it down as we go.

What we're building

The work comes first. Here's what's on the trail right now — including the decisions, the lessons, and the early stuff.

  • Early experiment

    Personal Context OS

    Capture preferences, routines, and goals, then export them as a portable Markdown pack your AI agents can query over MCP. Local-only for now: speak or type notes in the browser, download a zip, and serve the pack to Cursor or another agent.

    • MCP
    • Markdown
    • React
    • Node.js
    • TypeScript

  • WebGL playground

    Three.js Experiments

    A Vite + React gym for WebGL and React Three Fiber experiments. First up: Cat World — a stylized cat in a backyard. Mash the keyboard, watch it react.

06 — Team

The two of us

Two full-stack engineers. Side projects, experiments, and this trail.

  • Abhishek Kumar Singh

    Full-stack engineer

    Turns ideas into shipped products, with work spanning fintech, event platforms, and a steady run of side projects built for the fun of it. Away from the editor, usually travelling, filming, or prototyping the next thing.

  • Rakesh Saroj

    Full-stack engineer · Frontend focus

    Builds the parts of a product people actually touch — user-friendly interfaces and frontend applications, with an eye for the details that make an app feel effortless to use.
