Experience
- Archimedeshttp://archimedescalculator.com/
Archimedes is a graphing calculator for iOS and Android that features a powerful symbolic mathematics engine, fully automatic unit handling, a unique in-built formula library, and advanced animations.
- GOV.UK Verify
Digidentity is one of the certified companies in the GOV.UK Verify program. Their software makes online identity assurance straightforward.
- Structural Analysis Tool
I developed a structural analysis tool for the preliminary sizing of an arbitrary wing. The work involved combining complex aerospace engineering with software development.
- Orbit Design Tool
I developed an orbit design tool that automates the complex process of finding the optimal trajectory between two arbitrary celestial bodies.
- Neuronhttps://github.com/nielsandriesse/neuron
An experiment involving the use of an evolutionary algorithm for the optimization of a neural network’s hyperparameters, as well as the idea of having a group of neural networks work together to achieve better results than the group’s members could achieve individually.
- Session Corehttps://github.com/nielsandriesse/session-core-swift
I developed a Swift framework for Loki Service Node network-based messaging. Loki Service Nodes are servers in the Loki Project's decentralized network. The framework has full support for onion routing, as well as advanced handling of unreliable Service Nodes.
- Functionhttps://github.com/nielsandriesse/function
A framework for representing and performing numerical operations on mathematical functions in Swift. The framework allows the user to numerically approximate derivatives, integrals, roots and extremums of arbitrary functions.
- Speaker at Coder Factory Career Day
I gave a talk about best practices and what it's like to be a programmer.
