Software, SaaS, AI, and digital systems by Kweezi Perez Christopher, a software developer and digital architect in Kampala, Uganda.
The public GitHub projects shown here are a curated sample of substantial work I can responsibly disclose—not a complete inventory of my engineering work. Some of my most advanced systems remain private to protect proprietary intellectual property and architecture, client and partner confidentiality, security-sensitive implementation details, and commercially confidential strategy. Further details can be discussed where ownership, authorization, and confidentiality obligations permit.
