Hello fellow tech enthusiasts!
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
Whether you're looking to:
• Prepare for your next technical interview
• Get feedback on your resume or portfolio
• Solve challenging technical problems
• Learn modern system design and architecture principles
• 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.
If you're facing technical challenges, seeking career guidance, or wanting to level up your skills, I'd be thrilled to help you on your journey.
Let's connect and chart your path to success! Send me a message to start the conversation.

I’m very satisfied with our collaboration. From the very first day, we clearly analyzed my case, identified exactly what I needed, and created a structured plan that we are now steadily following. Communication has been extremely comfortable, it is genuinely enjoyable to listen and discuss ideas, and overall it has been a real pleasure to work together. I would absolutely recommend this collaboration without hesitation

Apostolos ranks as the top mentor I've worked with. He showcases remarkable patience and professionalism, quickly adapting to any changes in plans or learning paths. As a Frontend Engineer, I greatly benefited from Apostolos' guidance in developing two full-stack projects using newest technologies. Every session with him significantly enhanced my learning. I had to pause our mentoring sessions due to financial constraints, but when circumstances permit, I will definitely book sessions with him again.
