Long term, data only eSIMs – built with Claude Code
Firstly, I’m not a developer — but I am a very technical, over-50, product person and entrepreneur. This project started shortly after Claude Code launched. I had already worked on a few other AI coding projects, and decided to see how far I could realistically take something end-to-end. While I had some help from a developer, I increasingly felt capable of taking on more work myself. So about 9 months in the making, working full time on it past 2 months. Stack: Postgres, Next.js on Render. Monorepo with both frontend and backend services. Some takeaways from using Claude Code on this…
What it does
In the maker’s words, at launch
Firstly, I’m not a developer — but I am a very technical, over-50, product person and entrepreneur. This project started shortly after Claude Code launched. I had already worked on a few other AI coding projects, and decided to see how far I could realistically take something end-to-end. While I had some help from a developer, I increasingly felt capable of taking on more work myself. So about 9 months in the making, working full time on it past 2 months. Stack: Postgres, Next.js on Render. Monorepo with both frontend and backend services. Some takeaways from using Claude Code on this project: - I built all project pages directly in frontend JavaScript with mock data — no Figma or other layout tools. - In the early days, scope got out of hand; I learned quickly that Claude tends to overbuild unless tightly constrained. - Initially, I used Claude Desktop to refine prompts for Claude Code. - My skills with Git, SQL, Docker, and local/remote environments were shaky at first, but they no longer get in the way. - Using Flowbite CSS saved a lot of pain and made it possible to produce reasonably high-quality designs quickly. - Getting details right has always depended on pushing people, now that responsibility falls entirely on me. - About six months in, I adopted the Functional Core, Imperative Shell approach and documented it in claude.md (inspired by this HN post: https://news.ycombinator.com/item?id=45701901). - I built an Airbnb-style referral program in a day, after spending time on a detailed to-do spec and following the above approach. What Jetogo does: - Issues you long-term, data-only eSIMs for mobile data What is Jetogo for: - Saving money on travel roaming data costs - Secondary devices (e.g., a kid’s iPad, laptop, or backup connection) What we built: - Parse CDR usage data to calculate accurate user billing - Implemented pay-as-you-go and subscription options using Stripe - Subscriptions support rollover and overage, applied at the end of each billing period - Built referral, bonus, and coupon programs - Aggregate usage across multiple eSIMs under a single account and present a unified total Live now at: https://jetogo.com

Hola HN! Long time lurker, sometimes commentor, first time poster here. I’ve been working alongside my two co-founders and a few colleagues on a project I’m excited (and a little nervous) to share with you all! Like many of us, I’ve lived a tortured existence with AI coding (is it vibes?) over the past few months - I think November was a big moment with this. But, one thing I’ve noticed after building orchestration layer after orchestration layer is that the thing I always came back to was “what the hell is Claude Code actually doing?” Perhaps it’s because of the time Claude Code got…
- PLPairing LLM code generation with traditional templates2024 · github.com · ▲5
Hi, I’ve been exploring Claude 3.5 code generation abilities for a while and it looks like it can generate more consistent code than other models. However it would still be unmaintainable if you ask it to write a lot of code and it still sucks at system design. So, I’ve been playing around the idea of using the code repository with a template for directory layout and infrastructure, then adding the repository information to Claude and asking it to generate code. It seems that it works, if I pass the structure of some OpenAPI based backend it can update the API definition and implementation…
- CCClaude Code front end deploying to GCP via deterministic infra back endOct 2025 · ▲6
I’ve been exploring LLM-driven developer workflows and built a demo where Claude Code acts like a Replit-style frontend for infrastructure. - You write a prompt in Claude - Claude generates a workload spec - Humanitec receives the spec and deterministically deploys infra to GCP (via Terraform) - App is up in under 1 minute — no pipelines, no DevOps tickets The backend is policy-enforcing and built for enterprise use cases (used by large orgs like Apple, ABB, etc.), but the flow feels like magic for devs or agents. demo: https://www.youtube.com/watch?v=jvx9CgBSgG0 Repo:…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
