Over nearly a decade building web apps, I've developed a no-nonsense approach to deliver predictable results in a fixed timeframe.

Building an app goes beyond writing code - it's about understanding your business needs and delivering a tailored solution. With regular check-ins and an agile workflow, I ensure exceptional results that align with your goals.
I identify pain points in existing workflows and systems, then create tailored web solutions that address these challenges efficiently, ensuring long-term scalability and performance.
With experience across industries like insurance, real estate, and e-commerce, I bring cross-domain expertise to build apps that not only solve immediate problems but also adapt to future growth.
My approach is technology-agnostic: I evaluate project needs to choose the most suitable frameworks and languages, from SvelteKit to Ruby on Rails, ensuring the best outcomes for every unique use case.
By maintaining open and consistent communication throughout the development process, I ensure all stakeholders' needs are understood and prioritised, leading to software that fits seamlessly into existing operations.
I focus on building apps with excellent performance, prioritising speed, responsiveness, and scalability to handle increased user demand over time.
For teams new to modern development practices, I provide guidance and mentorship on adopting best practices in coding, deployment, and maintenance.
These are the apps and websites I've worked on over the years, each representing unique challenges and solutions.
I created this product to help people beat procrastination by shaping awareness for when, how and why they procrastinate.
I contributed to the development of this open source mindmapping software, which allows multiple users to work on a single mindmap at the same time. This was primarily created for use in public school classrooms.
I contributed to the development of an "un-Googled" version of Excalidraw, which removed Firebase as a storage backend. This development was in preparation for a whitelabeled version for Excalidraw which was ultimately deployed in public school classrooms. I contributed to both versions.
This tool simplifies daily rotation setup for professional Squad server hosters by providing immediate feedback on errors and a "rotation builder" that ensures correctness. This prevents skipped layers, reduces player frustration, and improves server retention. By guaranteeing error-free rotations, the tool saves valuable time for server owners, allowing them to focus on enhancing the overall gaming experience.
I migrated an existing Magento webshop to Odoo, enabling the customer to use all Odoo features, such as inventory and content management, effectively. It also enabled the customer to more efficiently manage localised variants of each store. This increased revenue and reduced costs, as it was no longer necessary to maintain two distinct systems.
Migrated an existing Wordpress website to Odoo, enabling the company to use pre-existing functionality in the ERP system to more effectively place their products and manage their existing inventory, thereby increasing sales. It also allowed them to de-duplicate their systems, driving down overall costs.
Contributed to the development of Sapiens' SCIP solution, which offers insurance providers based out of the DACH market an all-in-one solution for creating insurance products, onboarding customers and managing their claims.
Part of a mixed team of freelancers and FTEs, I contributed to the development of internal tooling to help with business operations. This included tools for home valuation and risk assessments, loan offers and cooperation with banks as well as various addons for Zoho CRM to streamline business operations and enable teams to work effectively.
One of the lead developers, I was a key early contributor when this app was still early to market. I was responsible for redesigning, developing and maintaining the GraphQL-based backend, enabling the team to efficiently serve complex product data to thousands of alpha and beta testers across desktop and mobile.
Through an external consultancy, I developed addons for the enterprise-grade ticket software OTRS. The functionality of these addons ranged from simple queue adjustments to fully fledged warehouse management systems. I also enabled a local county to accurately gather and report daily COVID-19 infections during the earliest days of the pandemic through the use of OTRS.
