AdTechium
Tech Lead / CTO
Mar 2023 - Present
Updated a NodeJS system which was last working in 2019; then migrated an AWS account (from one account to another). Rebuilt all EC2/TG/LB servers, RDS MySQL, Route 53 DNS and monitored all AWS infrastructure. Refactored a system from EJS/jQuery/Knockout to React/Redux. Migrated from AWS to Render.com afterwards, and currently working on multiple different apps while still monitoring and increasing features in the initial app. Working directly with CEO with a tech advisor. Turned a stalled codebase into three new production projects, both personally led and still running today. Currently doing maintenance work.

Lead Golang Developer
Jun 2021 - Mar 2024
Worked on a booking and captioning system, as well as a poker simulator. Worked together with the Chief Product Owner to clean the API specification file, as well as plan development and get the system just right. Joined the Are Media team in April together with the Chief Product Owner for the development of an admin for a sales website to lead an experienced team, but left in August due to company changes. Worked on both the captioning system and an OpenAI chat interface, and developed an app that creates stories using OpenAI. Created a system that could get speech to text captions with Twilio, Revai, Deepgram, Assembly AI, Soniox, Speechmatics and OpenAI. Accountable for shipping; drove the work personally. Within six months, my small team built 1,000+ tests in a project to harden coverage while coordinating with partner teams.

Ai-Media
Lead NodeJS Developer
Apr 2020 - Feb 2022
Worked on at least 7 different systems/APIs, ranging from human resources management to managing another developer working on a UK Parliament captioning system. Worked together with Product Owners (including CPO), other developers (back-end and front-end), project managers, and CTO. Created lots of different systems in a small amount of time. Delivered hands-on, led teams to ship, or ran both in parallel. Before leaving, I documented and simplified the projects, leaving them easy to understand and maintain; the largest system was left stable, well-tested, and operationally clean.

Senior Nodejs Developer
Jul 2019 - Apr 2020
Worked on the Kontrollor project, an IoT platform developed in NodeJS, with an administration/management platform for paid users. Created a front-end for testing. Worked together with the Product Owner to clean the API specification file, as well as plan development and get the system just right. Created a system that you could connect a few different devices with NodeJS code, like turning on a light switch from an API endpoint. Led delivery end-to-end; escalated to cross-team coordination for scope beyond a single owner.

Jan 2018 - Mar 2019
Worked on the Planetchat project, a chat platform developed in NodeJS, with at least 8 supporting systems. Had the same API endpoints working in REST, websocket, socket.io, binary connections (satellite). Worked together with the Product Owner to clean the API specification file, as well as plan development and get the system just right. Created a system that could scale any of its parts individually, with so many other supporting systems you would know it was turned off the second it went with emails, slack messages, and phone notifications. Brought in to own delivery hands-on; coordinated cross-team work when scale required. By the end, the project was stable, supported by multiple operational safeguards, and easy to maintain.

Pillrs
Nodejs Developer
Oct 2016 - Oct 2017
Worked on the Pillrs project, a smartphone application to help users that are suffering from addiction. Started as a small SMS platform using Twilio with automated testing, went to react native for front-end later on. Project stopped midway due to lack of funding. Created a system that could connect hundreds of people fast. Within my first month, I significantly accelerated project delivery.

Junior Developer
Jun 2015 - Sep 2016
Worked on five different projects during this time to get real world experience with programming knowledge. These projects were really simple, like basic REST endpoints with small changes to the front-end. Part time. Since I was learning, my objective was to get things working and done - and that's what was done.
