Sobre mim
I'm a self-taught full-stack developer specializing in Python and Django, with hands-on experience across the full stack — backend, front-end, and security. Over the past year, I solo-built Ospyral, a full-scale marketplace platform, implementing a custom crypto escrow payment system, fraud-prevention middleware, and Telegram bot integrations. I also develop WhatsApp booking automation bots for beauty-industry businesses. I enjoy owning projects end-to-end and bring that same care to every client engagement.

Sep 2024 - Feb 2026 • 1 yr 5 mos
Worldwide marketplace platform for selling creative and research work (art, writing, business plans, lessons, NFTs). Designed and built the entire product alone over ~1 year while learning to program. Built a custom crypto wallet and escrow payment system (OSP token, USDT, TON) with TonConnect wallet integration, quote expiration, and idempotent transaction handling to prevent double-charges. Implemented rate-limiting middleware with per-endpoint request limits and IP/user-based tracking to protect authentication, payment, and dispute endpoints from abuse. Built a device/IP/user-agent fingerprint banning system with automatic expiry and admin override. Developed a full admin/moderation panel for content review, finance monitoring, disputes, and withdrawal management. Added gamification (achievements, VIP tiers, gifts), a copyright certificate system for user content, and NSFW content moderation for artwork. Built companion Telegram bots for account security and quick profile access. Designed the front-end UI/UX, including animated backgrounds, interactive product cards, and a live-updating wallet sidebar.
