Full-Stack Development for Teams in Denmark
Async-first, demo-driven development, 3–4 hours from Danish time.
I'm Waseem Ahmad, a full-stack developer and AI engineer working with distributed teams since 2022 — 55+ projects shipped and Top Rated Plus standing on Upwork. Denmark's working day and mine overlap by 5–6 hours (Pakistan is just 3–4 hours ahead of CET), so collaboration happens in real time rather than across awkward handoffs. Recent European work includes Continuity, an M&A marketplace live at continuity.deals.
Based in Pakistan (UTC+5), just 3–4 hours ahead of Denmark — 5–6 hours of shared working time every day.
The challenge
Danish teams run flat, direct, and async-friendly — a working style that matches mine exactly. No status theatre: a scoped plan before work begins, working demos each week, honest written updates in between, and a response to any message within 24 hours.
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.
