I build Python automation systems, APIs, and bots that replace manual work and scale processes. From web scraping pipelines to Telegram bots and real-time monitoring platforms. I focus on solving the actual problem, not just writing code. What I build: • Automation systems that replace manual workflows (scraping, bots, scheduled tasks) • Backend APIs using Python & FastAPI (clean, scalable, well-structured) • Third-party API & webhook integrations (Stripe, Telegram, custom services) • Data pipelines & processing systems (collection → transformation → delivery) • Telegram bots with real-time alerts, commands, and business logic • Database design & management (PostgreSQL, structured & scalable) I don’t just write scripts - I build and run real systems used by actual users. Here are two platforms I developed from scratch: 1. CryptRadar Real-time cryptocurrency monitoring platform with active users and paid subscriptions. • Live data tracking & alert system • Telegram bot with advanced monitoring logic • Subscription system & payments • Fully deployed backend (PostgreSQL, APIs, automation) 2. Priceint Competitor price tracking platform for e-commerce businesses. • Custom scraping engine (handles JS-heavy sites + structured data) • Real-time price & stock alerts via Telegram • Multi-tenant SaaS with subscriptions & team workspaces • Analytics dashboard (price history, trends, opportunity detection) • XLSX exports, admin panel, and full backend infrastructure Both systems are built as real, production-ready products, not just demos. I also run Devlores ( devlores com ), backend development studio where I take on client projects alongside my own products. Before I start write anything I make sure I actually understand what needs to be solved. I keep things simple, well documented, and easy to maintain or build on later. Clear communication and delivery is key, and that's what you can expect from me. If you need something automated, integrated, or built from scratch - send me a message. I’ll quickly tell you if I can solve it and how I’d approach it.
