The most amazing...
...project I've led involved recreating a business' core software that doubled efficiency for internal employees and exponentially increased future features.
Work Experience
Full-stack Developer
Divvly
- Created a workflow management system for internal process automation. Workflows can be composed using different actions such as to-do, payment, the form required, and more, and can be attached to incoming orders.
- Mentored a software engineering intern from MIT in React Native development.
- Created a visual storage management web and mobile interface with drop-and-drop interactions using React and React Native.
- Implemented an automated deployment process on AWS using automated testing in a Bitbucket pipeline. The front end uses Jest, React testing library, and TestCafe, while the back end uses PHPUnit.
Senior Full-stack Developer
Leiden University Medical Center
- Listed all user requirements wanted and needed in meetings with different stakeholders.
- Designed the application's UI from scratch using Adobe XD.
- Set up the greenfield project as a full-stack developer with a React front end and Laravel PHP back end.
- Ensured maximum technical (e.g., OAuth) and non-technical (e.g., 2FA) security.
- Combined multiple data sources into insightful graphs using D3.js, Chart.js, and system warnings to make sure the client is compliant with the grant specifications.
- Ensured future reliability by adding unit, API, and E2E tests so that future engineers could update and extend the application while ensuring everything keeps working.
Senior Front-end Developer
New10
- Stepped into an ongoing project with 70+ microservices and was able to navigate the codebase and commit within 48 hours.
- Implemented Figma flow designs into scalable React front-end solutions.
- Extended and improved the core UI components library—as a senior—including components all juniors can only implement.
Senior Full-stack Developer
Uw-s
- Recreated the business' core application using React and a REST API to increase employee efficiency by reducing the time spent using the application by half—preventing the need to hire more personnel when scaling up.
- Created a flexible, automated matching system between items and deployment options based on tags, demographics, and timely data, like the weather, for over 300 clients.
- Oversaw the technical migration of a fixed-fee business model into a subscription-based business model using Stripe and ensured a seamless transition for the company and its customers.
Freelance Full-stack Developer
Utrecht's Studenten Corps
- Developed a user interface with an overview of the transaction data retrieved from bookkeeping software.
- Integrated a bookkeeping API with a secure user interface over a long weekend to minimize cash-flow problems as Studenten Corps' 2,000+ clients only pay after seeing the transaction overview.
- Created automated tests for this mission-critical application.
Freelance RPA Developer and Data Scientist
Bookchoice
- Automated extracting numbers and statistics on consumer behavior for suppliers, which was previously done manually in Excel.
- Created forecasting models on eCommerce KPIs (revenue, subscriber churn rate, etc.) in Google Data Studio on data queried from Google BigQuery and FireBase.
- Assisted a data scientist in writing complex SQL queries and their best practices.
- Created a scraper for information on events in the major Dutch cities, including parsing for prices, dates, artists, etc.
Full-stack Developer
Medina Anesthesia
- Developed a web application to schedule medical personnel at different locations.
- Created a connection to their bookkeeping software for invoicing based on data from the web application.
- Implemented a reporting dashboard with KPI statistics and predictions.

Moreover, given the complexity of the matching model, automated tests were created to ensure correct matching in a continuous development environment.
Medical Professional Planning Application
The application required traceability, mainly because it is in the healthcare sector. I was the main full-stack developer in charge of its front-end, back-end, UI/UX, and deployment onto servers.
