Different problems need different solutions. Having worked as a backend developer for clients across many industries, I get up to speed quickly and turn that into results faster.
Modern businesses run on web communication. Whether you need to consume or serve data, RESTful or bidirectional callbacks, I've got you covered.
Years of reporting, optimising and migrating data mean no dataset is too big. My toolbox includes MongoDB and Cognos BI, and I'm SQL certified.
// Portfolio
iGaming compliance on auto-pilot.
I founded Safe Comply ApS to take the jurisdictional headache off online gambling operators. Operators connect through clean APIs, and Safe Comply handles the local KYC and compliance requirements: identity checks against local identity services, Safe Vaults for load-balanced, redundant storage of the data and logs that auditors ask for, and integrations that keep up when the law changes.
Field Service Management for Danish service companies: planning, routes and documentation in one platform.
DetailsPlanner creates tasks automatically from service agreements and optimises the routes. Technicians log time, materials, photos and checklists in the GO app, and customers follow the job in the Dialog portal and confirm bookings by SMS. Integrations with ERP systems and e-conomic via API and webhooks take finished work straight to invoicing.
The person an ERP system provider calls when an SQL problem gets heavy.
DetailsWhen a problem goes deeper than day-to-day development (slow queries on large data volumes, complex data issues, things that need someone to dig all the way down), I'm brought in to find the cause and fix it.
Connecting an ERP system to accounting software, so bookkeeping data flows without manual re-entry.
DetailsMapping and transforming data between two systems that see the world differently, built so that transfers can be safely retried and nothing is booked twice.
// Skills
Select a skill to see the details.
// api-integration
Consuming and serving data over the web: REST APIs, webhooks and bidirectional callback flows between your platform and third parties.
// backend-development
Server-side applications and services built to run for years: clear structure, sensible logging, and a short ramp-up in new domains.
// reliability
Money and messages must arrive exactly once. Load balancing for redundancy, and idempotent design so retries never create duplicates.
// databases
Designing, optimising and migrating data, from small tables to large volumes, in document and relational databases alike.
// reporting-bi
Turning raw data into reports people actually use, through BI tools and web-based reporting.
// real-time
Live data to the screen as it happens: WebSocket feeds and telephony integrations.
