Muhammad Meluk · Software developer · Founder of DevSource.DEV LLC

You describe it. I ship it.

Bring the idea in whatever shape it's in — a sketch, a voice note, a spreadsheet you've outgrown — and take back working software. Built by the engineer you actually talk to.

What I build

Four things, done well. Not forty done badly.

Every project gets my full attention, honest judgement and direct communication — from the first line of code to the production handoff.

Custom software

Built to your shape, not theirs.

01

For the problems off-the-shelf tools can't solve — designed around how your team actually works.

  • Internal tools that match your real workflow
  • Automation that retires the spreadsheets
  • Integrations with the tools you already use

→ Software that fits. Not workarounds.

Web applications

Fast, modern, accountable.

02

Production web apps on the stack that ships best. Performance is a feature, not an afterthought.

  • React, Next.js, Astro and TypeScript
  • Auth, roles and row-level security that actually hold
  • Stripe billing that reconciles — webhooks verified and idempotent

→ Apps that load fast and convert.

Calling & telecom

Your dialer, your carrier.

03

Click-to-call, outbound dialers, IVR, recording and transcripts — built on the carrier you already pay.

  • Twilio, Telnyx, SignalWire, Asterisk and raw SIP
  • WebRTC agents that work in the browser, no desk phones
  • Compliance windows and abandon-rate limits enforced in code

→ Calls that connect, and logs you can audit.

Mobile apps

Native where it matters.

04

Swift and Kotlin when the platform should feel like itself, Expo when one codebase is the better trade.

  • iOS and Android, including store submission
  • Push, offline cache and signed release builds
  • Tested on real devices, not only a simulator

→ An app that is actually on the store.

What I don't build

Some doors stay closed, on purpose.

I don't take on work that conflicts with my Islamic beliefs, and I don't build desktop software. Better said here than halfway through a call.

  • Desktop applications
  • Alcohol, tobacco & vaping
  • Interest-based lending or BNPL
  • Gambling & betting

How I work

From wish to working software.

Four steps, no agency theatre. You say what you want, I tell you what it really takes, then I build it.

Fixed price. Fixed date. Late because of me? 10% off per full week, up to 30%. That's clause 5 of the contract, not a slogan.
  1. Say what you want

    Day 1

    30 minutes. You describe the thing you wish existed; I ask the questions that turn it into a spec — and tell you honestly if I'm not the right person.

  2. The honest version

    Day 2–4

    A one-page scope and architecture sketch with a fixed price and a fixed date. You see all of it before you sign anything.

  3. It gets built

    Week 1 onward

    Working software at the end of every week, not status updates. You steer something real from week one.

  4. You own it

    Launch week

    Clean deploy, documentation that doesn't lie, and the keys. Stay for maintenance or walk away — no lock-in.

About

One engineer. No relay games.

I'm Muhammad. I started DevSource.DEV LLC because too many founders get burned by agencies that promise everything and hand the work to someone they never meet. When you work with me, the person writing your code answers your email.

Got something in mind?

Tell me what you're building. I reply within 24 hours with honest questions — and, if it's a fit, a rough scope and timeline.
