I am a full-stack developer with focus on PERN/MERN stack and over 10 years of experience delivering software. I have a strong background as a software architect and have successfully led teams as a fractional CTO. I have worked with clients from diverse industries worldwide. I have successfully delivered over 20 projects for a range of clients, including early stage startups, growing startups, solo founders, digital agencies, and notable companies like Apple and Binance.
Technologies: LLM API Integration, AI Agent Development, Node.js, PostgreSQL, MongoDB, AWS, Heroku, Datadog, React.js, JavaScript, Next.js, Apollo, GraphQL, data visualizations (D3.js, Mapbox, Leaflet), headless CMS (Contentful, Prismic, Strapi), Wordpress, Tailwind, TypeScript, Web3 (ethers.js), Chrome extensions and more.
SEEKING WORK - Contract, Remote, USA, backend engineer
I am a backend expert, having built and maintained mission critical, low latency and highly available systems for many 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
Concrete examples:
* built the primary 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! (this was the third of currently four times I’ve built similar architectures for different companies)
* 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 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.
