Hi, my name's Jack.
I'm a senior fullstack developer with more than 7 years experience. I live in Berlin, have founded my own successful startups, and worked for Silicon Allee's biggest brands. I'm currently considering contracts in Berlin.
Java, Scala, AKKA, Spring, NodeJS, Golang, Rails, React, Mongo, SQL, AWS, CSS3, HTML5, UNIX, Android, communication, pragmatism, confidence, and learning new systems.
3D modelling is my hobby. I built a paid Saas 3D rendering service in Scala AKKA and Play with Firebase and Stripe. It let's users upload 3D files and render them on AWS EC2 GPU instances through a web interface. It then saves rendered imagery to S3 and syncs with the user's Dropbox.
I made every aspect of 3DRC, from the design and development to the marketing and legal paperwork. It took a lot of planning and skill to pull off and is now profitable.
Croove (Daimler), Lead backend developer (Contract)
Scala, AKKA, NodeJS, GO, AWS, Firebase, Postgres, Mongo, SNS
I worked as a contractor for Daimlers mobility startup Croove. letscroove.com allows people to rent cars from other users in Germany. I wrote APIs for payments, bookings, and customer service using AKKA, AWS SNS, Go, Scala, and NodeJS (Flow). I also assisted in hiring. The company was acquired by Turo in October.
Scala, AWS, Firebase, Postgres, Windows Server
I left startups to start my own. I built a profitable online 3D rendering service called 3drendercloud. I created every aspect of it, including design and marketing campaigns. The infrastructure is built in Scala Play and AKKA. It dynamicallly allocates AWS EC2 GPU machines to customers and remotely runs rendering software on them. It was a fantastic learning experience. I advertise with Google Adwords, Facebook, Youtube and Twitter. I handle payments via Stripe and logins via Firebase. Everything else is done programmatically in AWS.
Geeny (Telefonica), API and IoT developer (Contract)
Scala, Java 8, AKKA, NodeJS, AWS IOT, Firebase, Postgres, Mongo, Lambda
I worked as a contractor for Telefonica Germany's R&D offshoot Geeny. I wrote APIs in Scala and Node that managed a complex IoT ecosystem of custom hardware built on the Amazon IOT platform.
SoundCloud, Fullstack Engineer
Scala, Java, NodeJS, Golang, Ruby
I wrote Scala APIs and Node applications on an epic scale at SoundCloud. With over 150million users and hundreds of microservices, code had to be well tested and of the highest quality. I learned invaluable skills in communication, code quality, infrastructure, and debugging large applications. I became the lead developer on the Core Web team responsible for 150 servers and the code behind soundcloud.com.
GoEuro, Senior Java API Developer
Java, Scala, Spring, Play, AKKA
GoEuro is an agile and energetic Berlin startup that brings bus, train, and air travel together in one place. I worked as a senior backend Java engineer designing and building a brand new RESTful API, which was consumed by many applications and thousands of users daily. It also handled tens of thousands of euros in payments and had to be extremely secure and robust. It called many external parties, and dealt with sensitive information such as addresses and payments. It was a critical system, so bullet-proof testing and clear code planning were paramount.
MoreSleep, Tech Lead (Contract)
DevOps, Wordpress, Docker
I served as Tech Lead at the Berlin digital agency MoreSleep. I assisted in hires, managed the developer team, scoped projects, and lead development. I also used my experience in larger companies to modernize the studio's workflows and implement new development and deployment architectures.
EyeEm, Fullstack Node Engineer
NodeJS, React, ES6, Flux, PHP
EyeEm is one of the most famous startups in Germany. I worked there as a full stack engineer building a NodeJS-React isomorphic single page web app to serve 20 million users. It was a complex project with many challenges around responsive imagery, page load times, and asset size. We succeeded in making a fast and responsive application on all platforms.
