Founder & Software Developer

Self Employed • Self-employed

Feb 2024 - Present • 2 yrs 6 mos

Founder and lead developer of Argo Books, a complete accounting and bookkeeping software product for small businesses, built and shipped end to end. What I built: - A cross-platform desktop app in C# and Avalonia .NET (Windows, macOS, Linux): invoicing, expense and revenue tracking, inventory, rentals, customer management, and financial reporting. 150,000+ lines, 2,200+ commits. - A full-stack PHP and MySQL web platform: user accounts, subscription billing, a custom admin dashboard, a customer portal, and REST APIs. 90,000+ lines, 1,200+ commits. - Payment integrations with Stripe, PayPal, and Square, including webhook handling. - AI-powered features with Google Gemini, including receipt scanning and document import that read and structure data automatically. - Security features: AES-256-GCM encryption, two-factor authentication, and biometric login. I own the full lifecycle: design, development, testing, deployment, and ongoing maintenance. I also had contributions merged into major open-source .NET projects (Avalonia UI and LiveCharts2). Hire me and you get a developer who has built and launched real, production software from scratch, not just isolated tasks.
