I founded Xelitte and built Kelisu.kz, a classifieds marketplace for Kazakhstan, covering architecture, infrastructure, backend, frontend, and production delivery.
I built its Capacitor mobile app, resolved complex WebView and WebKit compatibility issues, and created a presigned S3 image-upload pipeline with automated WebP conversion.
I improved page-load speeds by approximately 6x through Cloudflare Workers caching and integrated SMS OTP authentication and payment gateways. I also built self-hosted localization support for the product.
At Datanomix.pro, I contributed to Gitoqlok and QATA.io, built a licensing server, and developed the Soterre PBI Analyzer with C# WPF and Node.js. I've also maintained a Discord bot serving more than 50,000 servers with distributed sharding for real-time traffic.
