At ITGate, I architect and maintain enterprise-scale CRM, healthcare, and real-time applications serving 20,000+ users across multiple projects.
I've reduced a 100,000-record sales import from three hours to five minutes through bulk inserts, queue jobs, and intelligent caching. I also optimize databases with more than 2 million sales records, resolve N+1 issues, and build reporting engines for complex hierarchical sales data.
I build live tracking dashboards with WebSockets, long-running progress flows with SSE, and Node.js microservices for large CSV, Excel, and PDF exports. I manage production infrastructure across AWS, DigitalOcean, and self-hosted servers using Docker, CI/CD, Nginx, load balancing, and zero-downtime deployments.
As a technical lead, I mentor 5+ developers, conduct code reviews, establish best practices, and guide architecture and performance decisions. Earlier, I supervised telecommunications infrastructure work and technical teams in mission-critical military environments.
