Hey, I'm Jannik

Big Pond can help you satisfy your curiosity!

Growing up in central Germany meant that the ocean did not play a big part in my life.
After arriving in Taiwan, "a tropical Island", I obviously wanted to explore the underwater world.
Unfortunately I quickly encountered two problems:

1. I'm naturally curious and would like to know what kind of animals are roaming around under the surface nearby. But it was hard to find accurate information outside of popular diving spots.

2. To be honest... I'm kind of scared of the ocean. The unknown and being out of your element makes me anxious.
After doing research on free and accessible data, I had an Idea that hopefully tackles both problems at once.

Introducing 'Big Pond'
An iOS App that lets you discover marine life at your closest beach, your next vacation spot or 'anywhere' else.
Additionally each animal will be grouped in to one of three categories.
Green: Wholesome and Harmless
Yellow: Safe, but don't get too close
Red: Warning, actually dangerous!

Happy Exploring!

App Store (iOS)

The “Wilo Assistant” makes the entire world of high-efficiency pump technology available on smartphones and tablets for sanitation, heating and air-conditioning specialists and specialist consultants of technical building equipment.
The free “Wilo Assistant” app is an easy-to-use mobile application and offers support in designing, customer consultation and installation.

I led the development for the 2019 Relaunch of the Wilo Assistant app.
I mediated interests of shareholders, designers, and developers to ensure practicability of the project.
I coordinated individual efforts to complete set milestones for both the Android and iOS app under time constraints.
Me and my team successfully delivered the product in time for the targeted industry trade fair.

Having a clear definition of deliverables and a set milestones is key to execute a large project.
Learning to let go and delegating tasks to the right individual is an important management skill for team leaders.
Use a natural break like this relaunch to evaluate the software architecture of a project and don't be afraid to make deep changes to improve code quality and shorten development time in the long run.

App Store (iOS)

Google Play Store (Android)

- Play on procedurally generated persistent Hex based map with high player number
- Gather resources
- Construct settlements, towns, cities
- Recruit and train soldiers and generals and engage in raiding, conquering
- Realtime tick based combat (think Hearts of Iron)
- Get involved in diplomacy/clans/factions wars and trading
- No or very limited PvE
- Visible and noticeable ranking system to spark competitiveness
- Limited focus on graphics until game is fun to play and balanced

In this project I try to implement as much as possible from scratch.
I learned how to implement:
- Websocket Multiplayer using socket.io
- Procedurally Generated Maps
- Hexagonal Tile Systems
- Firebase Authentication + Custom MySql Database
- A* Pathfinding
- Client/Server code sharing
- Client Side Dependency Bundling using browserify
- HTML5 Canvas graphics using pixi.js
- Automated deployment using GitHub Actions
