Multi-disciplinary software engineer with 4+ years of experience building web, mobile, backend, AI-powered, and cloud-native systems. I focus on creating scalable, secure, and user-centric solutions across fintech, e-commerce, and SaaS domains.
Get to know me better
I'm a multi-skilled software engineer with hands-on experience designing and building end-to-end digital products. My work spans frontend interfaces, backend APIs, Android applications, distributed microservices, and cloud infrastructure, with a strong emphasis on real-world usability, performance, and security.
My Approach: I believe in building systems that are simple to understand, easy to maintain, and scalable by design. I value clean architecture, clear documentation, automated testing, and continuous integration. My background in both development and technical support allows me to think beyond code and consider reliability, monitoring, and long-term maintainability.
What I Do: I build full-stack web applications using React, Next.js, and modern backend frameworks like Spring Boot and NestJS. I develop Android applications with cloud-backed APIs, design event-driven microservices, and integrate AI capabilities such as LLMs, RAG pipelines, and automation workflows. I also work with cloud platforms and DevOps pipelines to deliver production-ready systems.
Outside of building products, I enjoy exploring new technologies, improving my engineering workflow, mentoring others, and continuously refining my portfolio through practical, hands-on projects.
