Efaj Tahamid

Software developer

I'm Efaj Tahamid Rifat, a software developer, AI architect, and founder of CodeBros. Since 2022, I've been building software products and working across web development, artificial intelligence, automation, and blockchain technology.

I’m Dominik Lubański (call me Dominik). I help startups and businesses build scalable SaaS products, AI-powered applications, RAG systems, and workflow automation solutions, backed by 11 years of full-stack engineering experience and 5 years specializing in AI. I combine deep engineering expertise with AI-powered development tools like Claude to turn complex business ideas into reliable, production-ready solutions—delivering faster without compromising quality.

We help growing companies build scalable operational platforms, business systems, and AI-enabled workflows for integration-heavy and operationally complex environments. What sets Celadonsoft apart is our clarity before development: we start with discovery, solution design, and business analysis to define architecture, workflows, integrations, priorities, and the right development scope before build begins. This foundation allows us to deliver predictably for complex systems by combining product management, QA, solution design, and senior engineering, keeping complex software projects transparent, structured, and predictable from discovery to release. We are built for real business complexity and work best with growing and established companies that need operational platforms, multi-role systems, complex integrations, internal workflows, and software that supports long-term growth and operational scale. At the same time, our senior engineers use AI to accelerate delivery and reduce repetitive work while keeping architecture, technical decisions, scalability, and quality under senior engineering control. We primarily work with companies in Food & Beverage, Real Estate, and FinTech, and our strongest experience includes restaurant chains, multi-location businesses, operational platforms, workflow-heavy systems, and customer-facing digital products tied to core business operations.
