I'm a self-taught developer with 12+ years of experience who's passionate about elegant code, scalable architectures, and continuous learning. Currently serving as Co-Founder and CTO of Agents24x7, an AI startup building intelligent agent platforms that help businesses automate workflows and create AI-powered employees.
My expertise spans the full stack - from architecting scalable backend systems using .NET, Java Spring, and Microsoft Orleans to creating responsive frontend applications with React and NextJS. I have deep experience with microservices, AI platform development, and DevOps practices.
Throughout my career, I've:
• Built an AI agent platform from the ground up
• Transformed legacy systems from multiple incidents monthly to just 2-3 per year
• Implemented CI/CD pipelines and Kubernetes deployments
• Built and mentored diverse engineering teams across multiple disciplines
• Led R&D initiatives at fintech companies

• Understand AI platform development and integration
• Transition into leadership roles or startup environments
• Understand distributed systems and message brokers
• Improve your frontend or backend development skills
I tailor my mentoring to your specific needs and goals. I believe every developer has unique strengths, and I'm committed to helping you leverage them while addressing growth areas in a supportive environment.

My goal was to find a mentor to help me with a new project that required using Postgres, Prisma, NestJS, React, MaterialUI, and Node. I needed guidance to understand how to integrate these technologies effectively. Apostolos stepped in as my mentor and helped me grasp how each of these frameworks work and how to connect them seamlessly. From the beginning, he provided the necessary guidance and support, answering all my questions and addressing any issues I encountered. His expertise and patience were invaluable in helping me overcome the challenges I faced. Apostolos is a mentor I will definitely turn to again in the future. Thank you, Apostolos!
