Senior full-stack & AI software engineer building scalable, secure, GPT-4-powered web applications for enterprise impact.
SlovakiaWhat I'm looking for
I’m a Senior Software Engineer and Full Stack & AI Developer with 10+ years of experience building scalable, secure, and intelligent web applications. I focus on designing high-performance, data-driven solutions using modern frameworks and AI tools like GPT and LangChain.
Recently, I led design and development of a GPT-4-powered enterprise chatbot integrating LangChain, Elasticsearch, and Azure Cognitive Search—enabling 2,000+ employees to retrieve contextual knowledge instantly. I also engineered a cross-platform event management platform (React Native) across iOS and Android, improving user retention by 45% through enhanced UX and real-time analytics.
I strengthen reliability and delivery by streamlining CI/CD pipelines with Jenkins, Docker, Kubernetes, GitHub Actions, and ArgoCD—improving deployment reliability by 60% and reducing release time. I’ve also built a decentralized blogging ecosystem using Solidity, React, and NFT-based authentication for secure, tokenized content access.
I bring an engineering mindset that values clean, maintainable code and measurable outcomes. I’ve authored and visualized sentiment analytics dashboards with Python Dash, architected scalable enterprise applications with Django/Node.js/React, and optimized backends (including Elasticsearch and real-time analytics) to cut latency and accelerate teams’ delivery velocity.
