Available for remote work in any Time Zones
Software Engineer with 6+ years building enterprise and commercial products for NATO, Vodafone, BBC,
and CGI. Strong frontend core (JavaScript, React), extended into full-stack and AI — with hands-on
experience integrating LLMs into production environments, from building internal AI-powered agents
(e.g. prompt-driven data visualization tools) to optimizing CI/CD pipelines with custom AI agents.
Proficient with leading models across providers (Claude, Gemini, GLM, GPT, Mistral and others), with a
practical understanding of their strengths and trade-offs. Experienced with agentic development
workflows using Claude Code, Cursor and Kilo Code, and maintain a local model setup for specialized
tasks ranging from code generation to image and video synthesis.
I lead small teams, conduct code reviews, and mentor developers, while staying close to the customer
facing — presenting features and gathering stakeholder feedback directly. I care about performance,
security, accessibility, and scalable architecture, and apply principles like SOLID, SoC, and DRY to
keep codebases maintainable long-term. Comfortable picking up any stack.
