I build the kind of Python systems that do the work no one wants to babysit: crypto bots, automation pipelines, and scrapers that survive real-world bot detection. Async, production-grade, built to keep running long after I hand them over. What I ship: 🤖 Telegram & Discord Bots Alert bots, price-checkers, ticket systems, admin tools, full MVPs. aiogram and discord.py. Real error handling, auto-reconnects, rate-limit aware. Bots that don't go silent when the API hiccups. 📈 Crypto Price Tracking & Algo Trading Multi-exchange price watchers, arbitrage detection, pump/dump alerters, trading bots with real strategy logic. CCXT for the easy exchanges, custom aiohttp connectors for the 40+ that CCXT can't handle cleanly. Redis-backed snapshot stores, hard timeouts, distributed locks. 🌐 Web Scraping (anti-bot ready) I pull data from sites that actively fight scrapers. undetected-chromedriver, Selenium, Beautiful Soup, Scrapy. Captchas, rotating proxies, sticky sessions, rate limits, all handled. 📊 ETL & Automation Pipelines Async Python services that ingest messy data, clean it, transform it, push it where it needs to go. Scheduled jobs, error recovery, observability built in. Runs while you sleep. 🔗 API Integrations Exchange APIs, Google Sheets, Supabase, Stripe, webhooks. I connect systems that were never meant to talk to each other and make them work cleanly. 🗄️ Databases & Infrastructure PostgreSQL, MySQL, MongoDB, Redis. SQLAlchemy with Alembic migrations. Docker, docker-compose, task queues. Built for real production load. 🚀 Most automation projects break two months in. The bot misses an event. The scraper trips on a captcha. The pipeline silently drops half the records. You don't notice until a customer does. That's the part I build for first, not last. Tell me what you're building. I'll come back within 24 hours with a real plan, a real timeline, and an honest answer on whether I'm the right fit. If your project lives in crypto or trading, I can also share a long-running production system I built privately so you can see the bar I work to.

Most developers build what you ask for. I build systems that make you money or save it. I've architected production web platforms that serve over 10 million visitors without falling over. That's the kind of scale where one bad decision costs real revenue, so I've learned to make the right ones. I also build AI agents and automation that quietly strip cost out of a business by replacing manual workflows, cutting support load, and handling the repetitive work your team shouldn't be stuck doing. Here's what that looks like in practice: Web systems built to scale. Platforms engineered to handle serious traffic and growth instead of buckling under it. AI agents and integrations that cut costs. Custom agents and workflows that take over expensive manual processes and ease the pressure to keep hiring. Automation and bots. Tools that absorb the repetitive, time draining tasks so your team can focus on what actually moves the business. I work best with founders and businesses who want someone to architect the right solution, not just a pair of hands taking orders. You bring the problem, I'll bring the system that solves it. What I care about is the outcome: your business runs leaner, scales further, and costs less to operate. If that sounds like what you need, let's talk.
