Hi, I'm Amr Sakr, a Preferred Freelancer with 13+ years of software engineering experience. I build robust, production-grade software across multiple domains, with a particular specialization in algorithmic trading systems. I'm equally comfortable architecting a complex Expert Advisor, delivering a full-stack web application, automating a manual workflow, building a Telegram bot, or extracting data at scale from the web. Hundreds of clients have hired me for one type of project and returned for something completely different, because the underlying engineering quality and communication is consistent. What I build: Trading Systems (my deepest niche) • MetaTrader 4 and 5: Expert Advisors, custom indicators, scripts, optimization, backtesting • TradingView: Pine Script strategies, screeners, alert systems • NinjaTrader and similar platforms: automated strategies and indicators Software Engineering (broader practice) • Backend and APIs: C#, .NET, ASP.NET Core, SQL Server, RESTful services • Desktop Applications: WPF, Windows Forms, native Windows tooling • Web Applications: full-stack builds, dashboards, admin panels, integrations • Automation and Scraping: data extraction, scheduled jobs, workflow automation, Python tooling • Bots and Conversational Tools: Telegram bots, Discord bots, chatbot integrations, alert and notification systems • Integrations: payment gateways, third-party APIs, brokerage connections How I work: structured phased delivery, transparent milestones, no hidden scope-creep charges, deep requirements alignment before coding, and unlimited post-delivery support. I'm comfortable joining Zoom or screen-share sessions for briefs, walkthroughs, and live debugging. NDAs welcome. Whether you need a high-performance trading bot, a custom internal tool, a Telegram bot, a scraper that survives anti-bot defenses, or a full-stack web app, message me to discuss your project.
