PhD Candidate, ADAPT Centre
Nov 2020–Oct 2021
Software developer, EdgeTier
- At EdgeTier I primary worked on fulltext search and indexing. In
the process, I gained a deep understanding of PostgreSQL, along with Python search
and ORM libraries.
- I also contributed heavily towards the abstraction of EdgeTier's
backend system in order to better suit a multi-tenanted architecture. This is
a direction any SaaS company must take in order to speed up the onboarding
of new clients.
Apr 2019–Nov 2020
Full-stack software engineer, VSware (acquired by Visma)
- I improved several data-intensive endpoints,
including InSchool’s roll call and absence registration
pages. These pages are used by teachers across the Norwegian public
secondary school system (taking roll call with a tablet
or computer). My enhancements, taking load times
from multiple seconds to milliseconds in many cases, has at this
stage saved Norwegian teachers days of buffering time at the
beginning of class.
- I was the
regex guy in the office,
often tasked with writing scripts to modify huge portions of code, automate
tedious tasks, or enforce a coding standard rule across different
languages. I led the charge in transitioning date and time standards used
within Visma’s InSchool project to ISO-8601. This involved huge
collaboration across teams.
Nov 2018–Apr 2019
Software engineer, Datalex
- I worked on the airline pricing team, and wrote a web crawler to download,
index, and cluster pricing rule documentation (tens of thousands of pages
of legalese text). This aided other software engineers in retrieving
important information, and recognising related yet vague terms such as
’Category 4 fare’ and ’Record 3’.
- I pointed out issues with a deletion procedure on the Linux servers used by
the pricing team. The Linux kernel keeps an unlisted copy of a deleted
file until every program reading that file has closed it. For
months, Datalex’s QA servers kept running out of disk space, despite deletion
procedures in place to remove old files. My Linux knowledge got to the
bottom of this unexplainable bug.
Oct 2017–Oct 2018
Full-stack software developer, Webio
- I improved Webio’s underlying REST API’s readability and
maintainability, measured by a 40% reduction in lines of code, by
introducing object orientation and static utility functions in
areas with code repetition.
- I increased sales to new clients by rapidly creating high-demand
features. I successfully oversaw the creation, for example, of a smart
reply feature, a versioning system for Webio’s core functionality (the
bots creation page), and more mission critical features like the
ability for human agents to easily intervene in a conversation handled
by a poorly performing bot.

“Seán is a self directed learner who sets the highest standards for
himself and others. Very focused, very motivated, and an excellent
developer. He makes the difference because he goes the distance. There is
no mountain he will not climb. We had a lot of mountains.”
