The idea is simple: when it rains above 15mm/hr in your zone, you get paid automatically. No claim form. No waiting. Money in your UPI before you've dried off.<br> Phase 1 shipped a full working demo — Next.js frontend, Node.js backend, PostgreSQL, and a Python ML service for dynamic premium pricing and fraud detection. Phase 2 has been the interesting part: replacing text-based zone matching with Uber's H3 hexagonal grid for sub-kilometre payout precision, wiring a Thompson Sampling contextual bandit that learns which coverage tier each worker segment is most likely to buy, and running a SAC reinforcement learning agent in shadow mode to self-tune premiums against our loss ratio target.<br> The fraud detection problem turned out to be the hardest thing we tackled. GPS spoofing rings on Telegram are a real, organised threat to parametric insurance. Our answer was a Behavioral Coherence Score — four independent signal layers (accelerometer patterns, battery drain rate, cell tower triangulation, platform online status) that a spoofer has to defeat simultaneously to look legitimate. In practice they can't.<br> Built for Guidewire DEVTrails 2026. Still a lot of road ahead — GNN fraud detection, smart contracts on Polygon, causal inference for payout validation — but the core engine works and the tests are green.<br> If you're working on InsurTech, gig economy financial products, or parametric risk anywhere in South/Southeast Asia, I'd love to connect.<br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fyvaollycrkhs3ut2n535.webp" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fyvaollycrkhs3ut2n535.webp" alt=" " width="800" height="365"></a></p> webdev ai programming devops Daksh Gehlot Fri, 13 Mar 2026 07:15:19 +0000 https://dev.to/dark_sider_d2dee48479d5f0/guidewire-devtrails-hackathon-2g6e https://dev.to/dark_sider_d2dee48479d5f0/guidewire-devtrails-hackathon-2g6e <p>Really excited to share that I’ll be taking part in the <strong>Guidewire DevTrails Hackathon 2026</strong> with my team <strong>Greeninja</strong>. <a href="https://www.linkedin.com/posts/guidewire-software_register-now-guidewire-devtrails-university-activity-7301286029997527041-TYJB?utm_source=share&amp;utm_medium=member_desktop&amp;rcm=ACoAAFVylKEBIwCmml2CfcSyU44YrrhBcucqeOo" rel="noopener noreferrer"></a></p> <p>There’s something special about hackathons — the energy, the late-night brainstorming, and the thrill of turning simple ideas into real solutions in such a short time. I’m genuinely looking forward to building, learning, and experimenting alongside an amazing community of developers.</p> <p>Super grateful to be doing this with my incredible team <strong>Greeninja</strong>. Let’s see what we can create together.</p> <p>Let the hacking begin.</p> <h1> GuidewireDevTrails #Hackathon #Greeninja </h1> ai programming hackathon webdev
