What I do

Four things I build well

Every engagement is scoped in writing, built with weekly demos, and handed over with documentation.

Selected work

Trading platforms, Web3 apps, and bots I've shipped

Client projects with real users, real money, and real deadlines. Learning projects live on a separate list.

How I work

From first call to handover

No surprises: you know the scope, the price, and the progress at every step.

  1. 1

    Discovery call

    30 minutes, free

    We talk through what you're building, what exists today, and what done looks like.

  2. 2

    Written scope and quote

    Within 2 days

    A short document with deliverables, timeline, and a fixed price or weekly rate. No surprises later.

  3. 3

    Build with weekly demos

    Weekly

    You see progress on a live preview URL every week and can steer early. Code lives in your repository from day one.

  4. 4

    Handover and support

    30 days after launch

    Documentation, deployment on your infrastructure, and fixes for 30 days after launch.

Questions

Working together

All questions
  • Which countries and time zones do you work with?

    I work remotely from Pakistan (UTC+5) with clients in Europe, North America, the Gulf, and Asia. I keep overlap with European working hours and US mornings, and urgent issues are handled on WhatsApp regardless of the hour.

  • How do we start?

    Message me on WhatsApp or email with a few lines about your project. We book a 30-minute call, and within a couple of days you have a written scope and quote.

  • Do you charge fixed price or hourly?

    Both. Well-defined projects get a fixed price with milestones. Ongoing work or evolving products run on a weekly rate. Either way you approve the scope before anything is billed.

Have a trading platform, dApp, or bot in mind?

Send a few lines about your project. You'll get a reply within one business day, usually much faster on WhatsApp.
