Full-Stack Software Engineer
Alexander Sellström
Pursuing a career in peer-to-peer protocols and applications, leveraging the power of blockchain and zero-knowledge cryptograpy. Determined to build an alternative to the oppressive centralized internet.
About me
I'm a full-stack software engineer and cypherpunk. I'm ideologically motivated to create dissident technologies that protect our most essential liberties, even if our legislators fail us.
Hailing from Sweden, but born to an American parent, I speak Swedish and English natively.
What I am working on right now
Current Projects
A peer-to-peer imageboard protocol powered by blockchain and zero-knowledge cryptography. Emerald consists of a layer 1 blockchain for storing content identifiers, and a completely unique sharded peer-to-peer content delivery network for distributing user-generated content. This new architecture solves the latency and incentive issues that existing storage protocols like Swarm, Sia, IPFS, Filecoin and others suffer from.

Volunteer Manager for Polhacks
Uppsala Union of Engineering and Science Students (UTN)
2017 - 2018
Polhacks is an annual three day LAN-party and game festival held by UTN. For one year my main responsibilites included educating and managing ~40 volunteer workers and planning, procuring, and installing the equipment nessescary for powering hundreds of computers. Beyond my main responsibilities associated with my role, I had to assist my committee in other tasks such as hosting dinners for hundreds of people, procure sponsorships, hold tournaments, and more. This taught me valuable leadership and teamworking skills.

Academic Projects
Some relevant projects from my studies.
Bachelor Thesis:
A System for Creating, Sharing and Listening to Interactive Stories
Description:
Perhaps nothing explains the concept of interactive stories better than The road not taken by Robert Frost. His poem tells the story of a man following a road through the woods, when he comes to a fork in the road. Which way should he go? And how will this choice affect the rest of his life? In an interactive story, the author expands their story along multiple branches, and invites the reader to choose for themselves which path to take. They can also restart the story to go back and see what would lie down that other road.
Role:
Mobile app front-end in react and expo. I also wrote code for our nodejs back-end, configured all the servers, VMs, databases, and third-party services such as speech-to-text.
Software Engineering Project (15 credits):
Carsbnb
Description:
A cross-platform mobile application written in Flutter for renting privately owned vehicles. Like Airbnb for cars.
Role:
Back-end code and managing our Google Cloud stuff. I worked on front-end stuff when I didn't have anything better to do.
Natural Computation Methods for Machine Learning:
Neuroevolution for Automated Driving
Description:
Genetic algorithms for self-driving cars with spatial awareness in a simulated environment.
Role:
We pair-programmed all of it.
Program Design and Data Structures:
Flappy Birb
Description:
Clone of Flappy Bird written in Haskell. Not a particularly complex project, but it sets itself apart from the other projects here by being made in Haskell.
Role:
Coding the physics and animations, and other work related to graphical sprites.
Project 3:
PartyZone
Description:
A cross-platform jukebox app that lets you create a kahoot-like session. People at your party can add songs to the queue and upvote and downvote other songs to influence the order of the queue.
Role:
I made the back-end with Firebase.
