How Build Cache for React Native works: caching C++ your CI keeps recompiling

Hello there (General Kenobi&#x27;s favorite way to start the conversation),I’m Rashid, a sophomore at UT Austin. I built Rejourney.co (<a href="https:&#x2F;&#x2F;rejourney.co&#x2F;" rel="nofollow">https:&#x2F;&#x2F;rejourney.co&#x2F;</a>) to predict issues with your apps and websites before they happen, based on real user session recordings.Here is a silly video (with cats) on how it works: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=Z95MDxBXMjk" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=Z95MDxBXMjk</a>It’s open source, and the post link is the github repo, but here it is again: <a href="https:&#x2F;&#x2F;github.com&#x2F;rejourneyco&#x2F;rejourney" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rejourneyco&#x2F;rejourney</a>I originally built this because I had a campus freebie finder app that grew quickly, and I had a lot of users dm me on instagram about issues with the app’s onboarding and UX confusion. I initially lost about 340 users out of my 5,000ish users because of these issues, and I had to recover some by nudging them with notifications. It was a big pain, and I felt bad that I lost this many users to small and easy fixes. So I built Rejourney to predict that before it happens. Here is how it works:First, the SDK is installed on Web JS, Swift, or React Native apps. You then help the SDK a little with a few lines of tracking important events -- such as a subscription bought, a signup completed, etc -- before you ship the app. We called these “critical conversion events”.From here, Rejourney records the user session along with the meta data you set up, and relates it to the sequence of the user journey, each touch&#x2F;scroll&#x2F;pan interaction, and rage taps. If deemed an issue, it bundles in API response times and codes, ANRS, and crash traces into the context.A heuristic then bundles all the user recordings into similarity cohorts for processing, and finds similar user journeys and outcomes in relation to the critical conversion actions that matter to you. If a trend is found that is possibly worrying, it admits the user recordings into segmentation and processing by an LLM on our back (in this case Gemini for cost and speed, but it has been tested on GPT 5.5 if you decide to self-host and set this up on your side).If the LLM views similarities in the touch sequence frame by frame, it can determine whether the cohort is likely to present a negative outlook on the critical conversion event that matters to you. Based on the replays and all the surrounding context, it outputs a .MD file with the context and the fix that would patch it (which you can copy into your coding agent). Optionally, you can attach your github repo so the .MD file includes a code fix with the detected issue.Furthermore, this occurs at the scale of thousands of user recordings daily. We have seen how this works on a medium-scale, as Rejourney has been tested with about 2.5 million user recordings from people shipping the SDK. One of our users even emailed us reporting a 30% increase in onboarding after 2 weeks of fixing non-stop issues found.We have made it soooo cost effective to run with different strategies, that our first 3 paid users made us break even on costs…and this means more compute space for cool things later :DOther considerations and criteria: Privacy was also very very important as we have to consider GDPR, after the retention period (usually 7-days) we quantize all the user recordings, anonymize all the fingerprints and aggregate them into a general dashboard (similar to Firebase’s general analytics dashboard).I’d love to hear your feedback, critics, and requests in the comments! I’m all ears (or eyes since I’m reading).

I have 4 years of experience working with React, Next.js, and Node.js.Other than that, I have also done some work with React Native and Three.js.My last contract ended about 3 months ago, and I have been trying to find new work since then. I started with LinkedIn, then reached out through my network, HN threads, Wellfound, Reddit, and other platforms.I also tried reaching out directly to startup founders building things in areas I like, such as worldbuilding and writing-related products. But many of them are also early-stage and do not seem to have much funding or hiring capacity right now.At the moment, I can find around 6–8 jobs per week, but it is not moving forward. I am not based in the US, which is another hurdle.I am open to learning new things. I have also done some work and courses around LLMs and RAG, so I would be open to working in that area too.I’m wondering if I should continue with React&#x2F;Next.js and keep applying, or if it makes sense to switch to another stack.Has anyone been in a similar situation? What would you suggest? And how can I show experience in another stack?

Ask HN: I am not able to find a job. Should I switch stacks?

I have been trying platforms such as Work at a Startup, Wellfound, LinkedIn, and other job boards, but not much of remote hiring(outside US). Nothing on hiring thread as well.I have been working with react, next.js , react native and node.js from last 4 years and more. I wanna to join an early-stage startup, contribute closely to the product, and learn more about a startup.Whenever I find an interesting startup, I usually reach out through email or Discord. Most of the time, they are either not hiring, do not have the budget, or do not reply. I have also tried approaching founders with specific suggestions about how I could improve or help build their website or product but no luck.I have the flexibility to take some risk so idm working on contract, freelance type. I just wanna have try something like this.Do you have any suggestions?

Hi HN, I am the creator of Exfault. I am building autonomous AI agents that find vulnerabilities in Android apps.I have noticed there are growing number of AI native pentesting tools for web apps but very few for mobile or Android. With more mobile apps being shipped quickly due to vibe coding, I wanted to build an AI native security tool specifically for Android apps.Exfault combines static and dynamic analysis with AI agents using tools like adb,jadx, apktool for static analysis and reverse engineering, frida for dynamic analysis, hermes-dec for React native decompilation.
The AI agents have access to real Android emulators to peform navigation, explore functionality and validate vulnerabilities before reporting them improving both the quality of reports and also the rate of false positives.Instead of uploading an apk or aab, you can simply enter an Android package name (com.example.app), Our backend automatically acquires a compatible build, installs it in an emulator so the agents can test your app.For authenticated testing, you can provide test credentials and the agent will automatically sign in and continue exploring the authenticated attack surface. I&#x27;m also working on a human-in-the-loop login helper for more complex authentication flows involving MFA, Email verification etc.There&#x27;s a free demo available if you&#x27;d like to try it on your own app.I&#x27;d really appreciate your thoughts and feedback!<a href="https:&#x2F;&#x2F;exfault.com" rel="nofollow">https:&#x2F;&#x2F;exfault.com</a>

I built Opencom, an open-source alternative to Intercom for customer support chat, with knowledge-base and AI support, and mobile apps for push notifications etc.It includes a web widget, agent inbox, customer&#x2F;company profiles, conversations, realtime messaging, AI support and a live demo. The aim is to provide a simple, self-hostable foundation for teams that want Intercom support without being locked into a large SaaS platform.Salesforce has just announced its acquisition of Fin, formerly Intercom, for around $3.6bn. Customer communication is important infrastructure, and I think there should be a credible open-source option.Built with TS, NextJS, React Native &amp; Expo, and Convex backend for easy setup and ability for full self-hosting. Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;opencom-org&#x2F;opencom" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;opencom-org&#x2F;opencom</a>.Appreciate any feedback on architecture, self-hosting setup, and which Intercom-style features people would want before using it in production, along with any other thoughts.It is entirely OSS - no paid features behind a paywall. I hope this could become a community project.

I know about Work at a Startup, YC job, and Wellfound jobs, but they haven’t really worked for me so far.I don’t mind if the pay is low as long as there is some equity involved, or even a mix of both. Are there any other job platforms or should I approach startup by myself ? I’m trying to find a role where I can use that experience while also learning more about the startup side.If you are a startup, how would you respond to that?I have 4+ years of experience working with React and Next.js, and also react native, node.js
I’ve been doing contract work for quite a while, and I’m looking for something more involved before going back to regular corporate work.Are there startups working in this kind of setup, or any specific places where people usually find these kinds of roles?

Ask HN: How do I find startups hiring developers for low pay and equity?

I&#x27;m a developer with 4+ years of experience building production web applications for startups and clients.My primary stack is React, Next.js, TypeScript, and Node.js. I&#x27;ve also worked with React Native, Three.js, and GSAP, building everything from SaaS dashboards to interactive websites.I&#x27;m looking for freelance or contract opportunities (short or long term).
