Unfortunately, my application for the upcoming cohort was declined. I didn't get the chance to reach the interview stage or demo the MVP, but I fully respect the team's decision. I want to thank @lfgroblox and @RossTargett for the opportunity and for highlighting that professional funding paths exist for @Roblox developers. The first rejection always stings a bit, but giving up is not an option. The strategy remains simple: keep doing what you do best, and the results are guaranteed to follow. Keep Working🚀 #roblox #battleofcars #kolchanovdev

@lfgroblox ✅ Applied

1 month left to apply to our Roblox funding & mentorship program. We support serious solo devs + small teams with $10–15k funding, hands-on mentorship, real playtests, a focused cohort and launch support. Apply → lfgstudio.com Discord → discord.gg/bGhHfBRHUS

As a person of science (a physicist by education), I am sometimes amazed at how successfully variables or circumstances-align. Right now, everything is converging: 1️⃣ I am finishing a major project at my main job. The payout from this will allow me to fully focus on my personal projects without distraction. 2️⃣ My MVP for @Roblox is nearly complete. This isn't just a toy; it is a game built using professional tooling and backed by my extensive production development experience. 3️⃣ I stumbled upon a post from @lfgroblox looking for talent, and well, the talent found them. Their application window for Roblox investment has just opened. I believe this would be a mutually beneficial cooperation. They have the chance to invest in a project destined for success. I have the chance to guide this project to that success. Are these not signs of fate? (@RossTargett) #kolchanovdev #RobloxDev

Hey Jon! 👋 I recently released an open-source Kotlin client for the Polymarket CLOB. It’s seeing some healthy organic growth (devs are already building bots with it), and I’d love to get it verified by the team to ensure reliability for the community. Would you be the right person to connect with regarding this, or could you point me in the right direction? Thanks!

Polymarket is hiring cryptonative backend engineers to work on prod systems that move millions of dollars per day. You will be working on critical services that interface directly with blockchains. Top of market comp and equity. DM me and apply here: jobs.ashbyhq.com/polymarket/09f…

It’s been a month since the release of my open-source Kotlin library for @Polymarket . Here’s what the GitHub stats show for the last two weeks: 🔹 13 unique clones (developers are already trying the code out) 🔹 175 views 🔹 7 stars There are already two Issues with questions from newcomers, and what’s especially nice - messages of gratitude that they can finally develop on this platform using their favorite language. This kind of feedback is really rewarding. I haven't managed to get in touch with the Polymarket Team yet (@jon_amen @shayne_coplan). I hope sooner or later they do notice this lib primarily so it can be verified. Repo link: github.com/Vadim-Kolchano…

Happy Children’s Day (Wan Dek)! Today we celebrated with our son and contributed to the school’s charity drive. Small acts of kindness matter 😇 #WanDek #ChildrensDay #Thailand #Charity

year++ Congrats everyone on successfully shipping version 2026.0! 🚀 The past year felt like a challenging sprint. We definitely faced some critical bugs and had to deploy urgent hotfixes, but most importantly, we shipped amazing features and resolved countless tickets. For the upcoming year, here is my wishlist for you: + Stable Production: May your health and nerves handle any amount of high traffic. + Minimal Legacy: Archive old problems; don't try to refactor them into the new project. + Clean Code: Clarity in both thoughts and actions. + Zero Bugs: Catch those issues during the design phase, not in prod. Crucially, don't forget about work-life balance. Even the most robust enterprise servers need scheduled downtime for maintenance! Happy New Year, fellow developers! May your tech stack always remain cutting-edge, and your job offers always be above market rate. 💻🎄 #happynewyear #developer #coding #techcommunity #softwareengineering #2026goals #kolchanovdev

I’m posting this tweet here to send to journalists in the future when they ask: "How did you achieve success?" ​It all started from zero. Even with top-tier hard skills, you are nothing without social capital. Building it and breaking into the global market takes grit and the ability to show your work. ​But the moment just one of your projects takes off, everyone wants you. That’s life🤷, back to work🧑‍💻 #kolchanovdev #development

Good post👍 But trading isn't my thing, but hardcore engineering is. ​If you have the strategy but lack the coding skills, I can build this for you. ​I've built a custom open-source Java client for Polymarket because Java > Python/Typescript for high-concurrency/HFT ops. ​I offer the full stack: from code to VPS deployment. My guarantee is my public reputation. (github.com/Vadim-Kolchano…) ​DM is open. Let's build ☺️

programmers are making $10k-200k monthly on polymarket here's how they actually do it /// 1. arbitrage bots buy YES + NO when combined price < $1 example: YES at 48¢ + NO at 49¢ = 97¢ total you lock $0.03 profit per $1 no matter who wins trader "distinct-baguette" made $242k in 1.5 months doing this targets 15-min crypto markets where prices move fast python script polls API every 1-3 seconds, executes when sum < 99¢ /// 2. statistical arbitrage find correlated markets that drift apart "trump wins" vs "GOP senate control" should move together when spread hits 4-7%, short expensive one, long cheap one close when they converge trader "sharky6999" made $480k scanning 100+ markets per minute /// 3. AI probability models train ML models to estimate real odds from news/social data if your model says 60% YES but market at 50¢, buy trader "ilovecircle" made $2.2M in 2 months with 74% accuracy uses ensemble of 10 AI models, retrains weekly /// 4. spread farming buy at bid (5¢), sell at ask (6¢), repeat or hedge across platforms (short polymarket, long binance) trader "cry.eth2" made $194k with 1M trades high-frequency loop via CLOB API /// 5. copy-trading automation mirror successful whale traders automatically scan profiles, execute proportional trades one bot made $80k in 2 weeks copying near-resolved markets /// tech stack: python + requests library for API calls web3-py for blockchain interactions deploy on VPS for 24/7 operation polymarket has REST APIs for everything: gamma markets API (prices/volumes) CLOB API (place orders) data API (track positions) /// starting point: > build simple arbitrage bot first > fund with $100-1k for testing target high-volume markets (politics/crypto) > expect 50-70% win rate but focus on positive EV

@Polymarket @jon_amen @betmoardotfun Do you wanna improve your backend for trading use true server language?)

I’ve built a free, open-source Java (JVM) client for @Polymarket (MVP: L1/L2 auth, order create/cancel, websockets). If the community finds it useful and Polymarket Dev team (@jon_amen) approve it ☑️ I’ll keep developing it in my free time. 🔗 GitHub: github.com/Vadim-Kolchano…
