Ask HN: Freelancer? Seeking freelancer? (June 2026)

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.

Open to both short/long-term contract or a full-time position if the chemistry is there.

I fluctuate between:

- Deep learning / Neural networks - from architecture to inference. You might have used my ♥ Lovely Tensors library if you work with PyTorch (or JAX). Some CUDA, pytorch profiler, etc.

- Full-stack AI-adjacent applications - the usual LLM API tool-calling "agentinc" AI + full-stack web, ideally with SvelteKit (typescript, tailwind, shadcn, drizzle, etc).

SEEKING FREELANCER | Remote (US+EU only)

Stack: Vue3, Ruby+Sinatra, Postgres, Railway, Cloudflare

We've built a new platform in the electronic music space, currently in limited beta, and we are seeking freelancers who love electronic music to help us with design, UI/UX, and infrastructure (major bonus points if you're an artist or promoter, or you travel extensively with music as a primary focus).

1) We want to scale our infrastructure up to 500 RPS while minimizing costs when it isn't in a burst period, validate that with load-testing, and set up monitoring, alerts, and auto-recovery mechanisms where possible.

2) We'd like a complete design and UI/UX refresh. This can be an individual who holds both sets of skills or two distinct people.

Please email ${this_username}@gmail.com if this sounds like a fit; every application will receive a response.
