What I'm looking for

I seek roles where I can build secure, scalable web and blockchain systems, work with cross-functional teams, and drive measurable improvements in uptime, security, and user engagement.

I am a Full Stack Developer with 3+ years building scalable web applications, DeFi/crypto platforms, and enterprise security systems, with strong experience in Django and Linux-based infrastructure. I have delivered production-grade projects that improved uptime, performance, and user engagement while processing significant token volumes.

My recent work includes designing firewall logging and network security systems that reduced incidents by 80%, implementing staking and wallet integrations for 10,000+ users, and optimizing system performance to improve response times by 40%. I focus on secure, maintainable architectures, real-time analytics, and measurable outcomes.
