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 Head of R&D at ZuluTrade, I lead multi-disciplinary engineering teams across multiple countries while driving forward-looking technology strategies.
My expertise spans the full stack - from architecting scalable backend systems using .NET, Java Spring, Apache Pekko, and Microsoft Orleans to creating responsive frontend applications with React and NextJS. I have deep experience with message brokers (Kafka, RabbitMQ), microservices, and implementing DevOps practices that dramatically improve system stability.
Throughout my career, I've:
• Transformed legacy systems from multiple incidents monthly to just 2-3 per year
• Implemented CI/CD pipelines and Kubernetes deployments for improved reliability
• Designed resilient systems using patterns like outbox pattern and optimistic locks
• Successfully migrated critical systems while maintaining business continuity
• Built and mentored diverse engineering teams across backend, frontend, QA, and DevOps
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
• Transition into leadership roles
• 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.

5 out of 5 stars
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!

5 out of 5 stars
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.
