Everything I deliver includes: - Clean, fully owned source code (private GitHub repository) - Production deployment + domain setup - 60 days of free support and adjustments - Phased payments and a straightforward contract If you have a manual process costing you hours every day, send me a two-line message describing your needs — within less than one day, I’ll tell you exactly what I’ll build, how long it will take, and the cost. January–March 2026 schedule is filling up. Contact me today — I may still be able to take on your project.
