Rust Skill
@rustskill.bsky.social
We got tired of tools that only check if code runs. So we built one that argues back. 🦀 Real Rust challenges, real reasoning on https://rust-skill.com
Today is an very special day for us. After a lot of hard work and failed attempts, we got our 1st paying customer 🥳 This is EVERYTHING to us and we're buzzing to see the hard work and evolving with 100+ devs feedback, pay off! #buildinpublic #rustlang #learnrust #devtools
Day 27/30 building @rustskill.bsky.social Revamped the llm to be more concise in its questioning. #buildinpublic #saas
Day 26/30 building @rustskill.bsky.social Finished the mvp of the rag build. Professor crab now recommends learning materials in our knowledge base based off of gaps in the users knowledge. #buildinpublic #saas
MASSIVE change in our MVP We’re listening to your valuable feedback! Pushing update soon -> rust-skill.com

Week 1 of MVP launch wrapped up! > Ads running at a 1% CTR (decent!) > 65 🦀 developer sign-ups (solid!) > Only 50% of signups actually tried a challenge (🚨🔴) Users who did try it, loved it. We must have a UX issue of directing signups to their first free challenge. We're pushing an update! LFG
Everyone says big tech interviews are about speed. They’re not. They’re testing how clearly you think, how calmly you reason, and how well you explain your choices under pressure. Here’s what they’re really assessing 👇
Stop memorizing Rust Start reasoning in it 🦀👇 rust-skill.com Daily challenges that test your logic, not only syntax #rustlang #learnrust #devtools #buildinpublic
Everyone says #rustlang is hard. It is. But not for the reasons you think. The syntax isn’t the problem, your thinking is. Rust quietly forces you to reason like a systems engineer. 🧵👇 What Rust actually teaches you (and why it makes you a better dev)

@realtuan.bsky.social · 11mo agoDay 25/30 of building @rustskill.bsky.social We launched the MVP yesterday and the first ad results are in! >Spent €49.95 on Reddit ads >47k impressions / 225 clicks >0.58% CTR / €0.20 CPC >8 signups (3.5%) – low CTR but steady conversions #BuildInPublic #RustLang #SaaS #DevTools #MVP
Rust 1.91.0 dropped recently. Just had time to dive in and it’s quietly powerful. No flashy headlines, just small upgrades that make Rust faster, safer, and more universal...
Most Rust learners stop at ‘it compiles.’ Senior devs explain why it works. 🦀 RustSkill forces you to do that. Take the challenge → rust-skill.com #rustlang #learnrust #devtools #buildinpublic
We've spent the whole week revamping our entire UX/UI Landing + challenge page, ready for launch Any feedback is appreciated! #buildinpublic #learnrust #rustlang
Day 22/30 building @rustskill.bsky.social Our llm integration is finally behaving and talking like a real interviewer! #buildinpublic #saas
Day 21/30 building @rustskill.bsky.social Updated landing page coming together nicely. Hopefully increases conversions #buildinpublic #saas
Day 20/30 building @rustskill.bsky.social LLMs really suck at reading between the lines. Had to add in a bunch of specific commands to stop professor crab from doing some strange shit. #buildinpublic #saas
Day 18/30 building @rustskill.bsky.social Mainly focused in on cleaning up the codebase ahead of Mondays release. #buildinpublic #saas
Day 17/30 building @rustskill.bsky.social Restructuring the question flow #buildinpublic #saas
Day 16/30 building @rustskill.bsky.social Tinkering with the cadence of questioning of the llm. #buildinpublic #saas
Day 13/30 building @rustskill.bsky.social Found some areas to improve on the llm whilst dogfooding the app. #buildinpublic #saas
Ive been dogfooding @rustskill.bsky.social and I have to say the llm is already a very helpful tool. I have it implemented to use the Socratic method. Still needs a fair amount of improvement though as I find it still does not have very accurate questioning threads. #buildinpublic #rustlang #saas
Day 12/30 of building @rustskill.bsky.social Improved llm context ingestion. #buildinpublic #saas
Day 11/30 building @rustskill.bsky.social Finishing up the end to end tests for the platform. #buildinpublic #saas #rustlang
Day 10/30 of building @rustskill.bsky.social Turns out memes do really well over other image formats when doing ads on Reddit. ctr jumped to over 1% on the best performing one. #buildinpublic #saas
Day 8/30 of building @rustskill.bsky.social Put the finishing touches on the MVP. Looking good for launch tomorrow! #buildinpublic #rustlang
