About

The Nationale Postcode Loterij is the largest charity lottery in the Netherlands. Every month, players can

win great prizes and support charitable organizations.

Project

The first project was the brand new Vriendenloterij App: show all experiences that can be visited (with

the membership card) in a list and mapview. We used Kotlin Multiplatform and Jetpack Compose. We

designed it feature-driven and architected to follow a typical MVVM clean architecture approach with

view, use cases, repository, data sources and low level drivers. After launch, the app blew up to 300k

downloads. It proved scalable and resilient. Test cases were running following a test pyramid and

running on Bitrise CI/CD to maintain quality levels.

I leveraged my network to introduce A+ developers into the team. I also interviewed and did technical

assessments with several developers. Because of the longer absence of the Product owner, I jumped on

the opportunity. As an interim-Product owner I involved all relevant stakeholders, created user stories,

set up meetings, and communicated conclusions of meetings to the team. I led sprint demos and

worked on the roadmap. I learned that a good PO has to communicate on different levels of abstraction

and I learned to control my eagerness to avoid over-promising.

I initiated bi-weekly tech meetings. Out of this came the choice to switch to Server driven UI due to

multiple campaigns. Most business logic was moved out of the Apps and into the back-end. Definitions

for UI elements became more strict and Figma designkit became the "source of truth"

. Benefits were:

more flexibility for the marketeer in creating campaigns (using Storyblok). Downsides were: longer

loading times, even after caching was implemented in the back-end. Also more responsibility for the

marketeer.

Project Had talks with flash supermarket delivery companies and a B2B proposal. The B2B proposal DailyChef spending per user whilst the user their App. Investigated a project proposal to offer DailyChef as a whitelabel app for existing food content companies that don't yet have or want a better app experience. I launched a landing page, made a list of prospects and started engaging with them. Interviewed over 100 marketers, business leaders, account managers and brand ambassadors to gain a deeper understanding of the required team structure, employee and marketing costs to get to 10k MAU. Honed my interview skills for non-technical jobs. Did market research for the best business model(s) and ways to raise money with (angel) investors. Refined and pitched the idea for investors, incubator and accelerator programs.

My tasks Understanding customer pain points, making a B2B proposal. B2B sales: creating a white label B2B solution and proactively selling to food content players worldwide. Recruitment skills: interviewing co-founders, marketers and account managers. Business modeling and market research to reach certain KPI's such as 10k MAU. Speaking and networking with high networth individuals, angel investors and institutional investors.

I guided the 2 Android developers in switching to I explained Uncle Bob's clean architecture to them and made examples of every I also explained the benefits of HAL. Then I introduced Proguard, and explained the risks of using third-party libraries. We removed almost half of the external libraries. The core payment processing solution in the App was developed as a giant state machine using EventBus to pass around messages. I started refactoring and removing this step by step, while also adding test cases to the existing test framework. This was also the first time using continuous deployment instead of gitflow. Introduced Material design 3 to work towards more consistency across apps. My tasks Rapid prototyping, Bluetooth Low Energy, ktor web server, qr code generating Delivering an MVP version within time and budget. Introducing Kotlin, clean architecture. Explaining security threats: third party libs, no proguard Improving architecture step by step. Removing EventBus.
