Hi, I’m Akezhan 👋

• Aspiring Cloud | AI | Backend | Blockchain engineer
• Prev. Senior software engineer at EPAM Systems

My journey in Software Engineering began at the nFactorial Summer 2018 Bootcamp. Over the past 7 years, I have evolved from creating demo web applications to architecting and delivering a resilient, high-performance analytics system for a globally operating logistics company, HAVI. I am passionate about developing highly performant applications and designing developer-friendly infrastructure to deliver high-quality features with speed and efficiency.

My interests span AI, Large Language Models (LLMs), cloud computing, programming, finance, and blockchain technology. Currently, I am working on several AI-powered and highly available Software-as-a-Service (SaaS) products while pursuing AWS Cloud certifications to deepen my expertise.

I have extensive experience with technologies such as .net (2020–2021), Java, and JavaScript (2018–present). My portfolio includes building single-page and hybrid web applications using React, creating games with Unity and Godot Engine, designing backend services powered by Node.js and .NET, delivering solutions on cloud platforms like Microsoft Azure and AWS.

Looking forward to building meaningful connections and exploring possibilities in tech together!
