About Codex Central

Codex Central is a subscription-based software development service (SDaaS) founded and led by Roberto Silva, a Senior Fullstack Engineer and Solutions Architect with over 15 years of experience. Unlike traditional agencies, every project is handled directly by the founder with a select team of senior developers. They offer three subscription tiers (Starter, Growth, and Apex) providing 40 to 160 hours of development per month, covering web applications, cross-platform mobile apps, AI integrations, and software performance optimization. Their async-first workflow uses a proprietary StackBoard platform for request management, and clients retain full code ownership. The model is designed for startups validating MVPs, SaaS companies scaling their products, and established businesses needing on-demand senior development capacity without the overhead of full-time hires.

With minimum project size of $1,000+, hourly rates of $50-99/hr, they are accessible to smaller businesses and early-stage companies.

Things to Consider

Small team size means limited capacity for large concurrent projects or fast scaling requests
Senior staff may be stretched across multiple accounts, reducing dedicated attention per client
Wide service menu risks spreading capabilities thin; clients with complex requirements should verify depth of expertise in their specific need
Founded in 2023, giving them a shorter track record than more established agencies in this space
