Into Clear Solutions
I'm Michael Sintim-Koree, an IT professional with over two decades of progressive experience in IT management, systems administration, software engineering, and e-commerce operations across multiple countries.
Currently serving as E-commerce, Operations & IT Manager at Waverly Cabinets, I oversee IT infrastructure, Microsoft 365 environments, network security, and cloud migration initiatives — delivering measurable improvements in system reliability and operational efficiency.
I am also a proud educator and lifelong learner, currently pursuing a Doctorate in Information Technology at Walden University. My aspiration: to become a world-class IT Solutions provider.
Beyond traditional IT, I design AI-enhanced automations and apply prompt engineering to accelerate development cycles — integrating LLMs, agentic workflows, and tools like n8n and Power Automate to solve real business problems.
