I help startups with the UX/UI and web design of their products. This includes web apps, websites, landing pages, copywriting, and I can assist with frontend development where needed. My background of launching my own products and being a full stack developer helps me create practical designs that balance usability, aesthetics, development effort, and performance. I work to fixed price quotes for self-contained projects.
---
The best live example of my work is Checkbot (https://checkbot.io/), a browser extension that tests websites for SEO/speed/security problems. The entire project is my own work including coding the extension itself, UX/UI design, website design (the homepage is optimised to load in 0.7 seconds, 0.3MB data transferred), marketing, website copy, and website articles on web best practices.

Willing to relocate: no, but willing to travel/visit. I'm flexible with working hours, I usually work with clients from either Western Europe or the USA.
I do dev/devops/security, usually for startups or scale-ups or other small orgs with limited resources, and I've been doing that for 15+ years. So, if you:
* Have a slow web application that’s often down?
* Want to improve security and don’t know where to start?
* Have a legacy system that needs to be replaced?
* Are considering an acquisition but not sure about the technical side?
I can help with that. For example, in the past I have:
* Massively improved performance and reliability for a data visualization platform.
* Led a large effort to improve security for a cybersecurity SaaS.
* Built a micropayments system for a prominent media startup.
* Rebuilt an aging e-learning platform from scratch for a GDPR compliance SaaS.
* Conducted technical due diligence for acquisitions.

I am a backend expert, having built and maintained mission critical, low latency and highly available systems for several companies over the last 10 years, in addition to over 20 total years of software development experience. I learn new things extremely quickly. AWS preferred but not required (I hold a variety of certs, available here: https://www.credly.com/users/jon-north.ad78f0c8)
You will like working with me because I:
* hold your goals as my priorities
* communicate verbosely yet synthesize well
* my rates are reasonable in exchange for the value I deliver
* I guarantee I will get the job done
* built the streaming data architecture for realtime game player tracking information (all games, 50ms SLA) and game stats for one of the top 3 US sports leagues (can’t name drop!) using Redpanda/Kafka on Azure+Terraform, and implemented its developer portal using Gravitee to provide first class streaming API support and monetization. Also built, deployed and maintained their ask-a-question-get-a-true-answer AI bot to expose 20+ years of stats to natural language fan questions!
* Implemented a vector DB for one of the leading AI image hallucination platforms (millions of users) to provide an image similarity service.
* replatformed dozens of complex quant jobs to AWS Lambda for a startup hedge fund (~$1B AUM), vastly improving QoS and maintenance cost. Line 1 to platform-in-prod time 3 months, including refactoring for fit. This was mission critical cannot-fail stuff and required extensive proof of correctness.
* built a ~50 node, AWS, Dockerized, Terraform-deployed distributed system to provide realtime, transformed trade data from crypto exchanges to a Kafka pipeline and data lake (fodder for an analytics platform). Met 5000msec SLA across arbitrarily many exchanges and ticker symbols. Blue-green deployment for complete CICD safety. Cloudwatch metrics proved SLA was met and provided general system oversight.
* built a framework to collapse dozens of singleton ETL programs into one config-driven, simple C# application performing the same functionality at ~80% reduction in maintenance cost year over year.
