Full-Stack Development for Teams in Belgium

Built Continuity for the Belgian SME market — live at continuity.deals.

I'm Waseem Ahmad, a full-stack developer and AI engineer — and Belgium is a market I know first-hand. I built Continuity, an M&A marketplace for the Belgian SME market and the first of its kind there, using React, Supabase, and Claude AI; it's live today at continuity.deals. Pakistan is only 3–4 hours ahead of Brussels, so we share 5–6 working hours daily, with the rest running on written updates and weekly demos.

Based in Pakistan (UTC+5), just 3–4 hours ahead of Belgium — 5–6 hours of shared working time every day.

The challenge

Most developers pitching Belgian companies have never shipped anything for the Belgian market. I have: Continuity, an M&A marketplace for Belgian SMEs, is live at continuity.deals — built end to end with React, Supabase, and Claude AI, and delivered with the same scoped, demo-driven process I bring to every engagement.

What I build

Full-Stack Web Applications

Next.js, React, and Node.js applications built end to end — from data model and API to a deployed, documented product.

Healthcare & HL7/FHIR Integration

Regulated healthcare systems, including an HL7 gateway that processes 10,000+ clinical messages a day from 200+ hospital monitors.

Fintech & Regulated Backends

Compliance-heavy backend engineering, including an SEC Reg CF crowdfunding platform shipped with 248 passing tests and zero production bugs.

AI Features & Integrations

LLM-powered product features, such as the Claude AI capabilities built into the Continuity M&A marketplace.

Marketplace Platforms

Two-sided marketplaces from schema to launch — Continuity (M&A deals) and HomeBrigadier (UAE services) are both live today.

APIs & System Integration

REST APIs, webhooks, and third-party integrations delivered with documentation and automated tests.

How we work

Most MVPs ship in 3–6 weeks; complex platforms are scoped individually once the requirements are clear.

01

Intro Call

A 30-minute conversation about your project, goals, and timeline. No commitment either way.

02

Scoped Proposal

A written scope, architecture outline, and quote. I respond to every message within 24 hours.

03

Weekly Demos

You see working software every week, with written progress updates in between. No black boxes.

04

Ship & Handover

Deployment, documentation, and a clean handover — you own everything I build.

Frequently asked questions

How much overlap do you have with Belgian working hours?
Pakistan (UTC+5) is 4 hours ahead of Belgium in winter (CET) and 3 in summer (CEST). We share 5–6 working hours every day — the same rhythm I used while building Continuity for the Belgian SME market: live collaboration in your morning, written updates for the rest.
What happens when your day ends and our Brussels afternoon is still running?
It is the pattern Continuity was built on, so I can describe it from practice rather than in principle. My working day covers your morning and the first part of your afternoon; from mid-afternoon Brussels time onward I am off, and anything raised then is picked up at the start of my next morning, which begins before yours does — so answers are usually waiting when you open your laptop. In practice that pushed the decisions needing a conversation into the morning window and left the rest to written updates, which never became the bottleneck people expect it to be. Every message gets a response within 24 hours. Time-critical items are best flagged during the overlap so they can be handled live.
How does a Belgian company contract an independent developer in Pakistan?
Two routes. A direct services agreement with defined milestones, invoiced on completion, drafted in English — in a country that runs its administration in both Dutch and French, English is usually the path of least resistance for everyone at the table. Or a contract through Upwork, where escrow and payment protection sit with the platform, which is often simpler for a first engagement. I work as an independent contractor supplying services, not as an employee. If your accountant needs invoices to carry specific wording, a reference, or your company number — in Dutch or in French — tell me at the outset and that is how they are issued.
Do you quote in euros, and how does payment work from Belgium?
Quotes are issued in US dollars, and the starting figure noted below is USD. The euro amount depends on the exchange rate the day you pay, so quoting a EUR figure here would guarantee it was stale by the time you read it. What does not move is the scope and the price: both are written down after the intro call and hold for the project. Payment comes by bank transfer, Stripe, or through Upwork, whichever fits your process. Your own BTW or TVA treatment — whichever language your bookkeeping runs in — is worth confirming with your accountant, since it depends on your registration status rather than anything at my end.
How does an engagement start?
With a short intro call — 30 minutes to talk through what you're building and whether I'm the right fit. If we're aligned, you get a written, scoped proposal covering deliverables, architecture, and timeline. I respond to every enquiry within 24 hours.
How does communication work day to day?
Written updates as work progresses, a demo of working software every week, and async-first communication over email or Slack. You always know what was done, what's next, and what's blocking — without scheduling a meeting to find out.
How do contracts and invoicing work?
A straightforward services agreement with milestones, or a contract through Upwork if you prefer escrow and their payment protection. Payment by bank transfer, Stripe, or through Upwork.
Who owns the code and intellectual property?
You do. Full IP ownership transfers to you — source code, documentation, and infrastructure configuration. Repositories are set up under your organisation's control from the start wherever possible.
What does an engagement typically cost?
Most engagements start around $5K; smaller well-scoped work is considered case-by-case. After the intro call you get a fixed, written quote — no surprises mid-project.
