Work

Experience

Senior Software Engineer

Kfcow

Key accomplishment

  • Redesigned the entire data management architecture using Redux Toolkit, working across 50+ components to eliminate critical performance bottlenecks. The new system improved platform efficiency by 45% and became the foundation for how we handle state across the application.
  • Led a major frontend optimization effort for our video streaming platform. By implementing React.memo, strategic lazy loading, and intelligent code-splitting, we achieved 30% faster page loads and 25% fewer bugs. The Lighthouse score jumped from 68 to 94, making the platform noticeably faster for users.
  • Rebuilt our Django REST API infrastructure from the ground up with optimized queries, connection pooling, and a Redis caching layer. Response times dropped from 800ms to 480ms (40% faster) even as we handled 3x more traffic.
  • Designed and built a distributed streaming system using Celery, AWS S3, and CloudFront CDN that now powers our entire platform. It handles 100,000+ concurrent streams with sub-second latency and maintains 99.97% uptime.
  • Completely transformed how partners integrate with our platform by creating comprehensive API documentation with interactive Swagger examples and detailed SDK guides. Integration time went from 2 weeks to 3 days, which directly enabled 15+ new partnerships.
  • Drove engineering excellence by establishing automated testing (92% backend, 88% frontend coverage) and modern CI/CD pipelines. Deployments that used to take 2 days now complete in 4 hours, and failures dropped by 60%.
  • Created technical standards and architectural patterns for service communication, error handling, and observability that have been adopted by 3 engineering teams. This work reduced onboarding time by 40% and established consistency across our growing engineering organization.

Senior Frontend Developer

Upcall

Key accomplishment

  • Built the frontend architecture for an enterprise calling platform from the ground up, serving 10,000+ businesses and 500,000+ monthly users. Maintained sub-2-second page loads through careful component design and efficient state management patterns.
  • Developed a real-time analytics dashboard using custom Chart.js visualizations that processes 1 million+ data points. The dashboard increased user engagement by 40% while actually reducing server load by 35% through smart data aggregation.
  • Led a complete UI/UX overhaul across 40+ core components, implementing responsive design and WCAG 2.1 AA accessibility standards. Support tickets dropped by 30% and mobile conversions improved by 22%.
  • Established a comprehensive testing culture with 85% code coverage, E2E testing, and visual regression testing across 120,000+ lines of code. Production bugs decreased by 25%, and the team gained confidence shipping features faster.
  • Optimized application performance by implementing code-splitting, removing unused dependencies, and modernizing the build pipeline. Bundle size went from 2.8MB to 1.1MB (60% smaller), and the Lighthouse score improved from 62 to 91.
  • Standardized the development environment using Docker so it works identically on Mac, Windows, and Linux. New developers can now set up and start contributing in hours instead of days, cutting onboarding time by 20%.
  • Built code quality infrastructure with automated linting, pre-commit hooks, and technical debt tracking. Wrote detailed technical guidelines covering state management, API patterns, component architecture, and performance optimization that the team still references daily.

Senior Full Stack Developer

Oracle

Key accomplishment

  • Built the Oracle Cloud Infrastructure Database Migration Service from scratch—a system that moves massive enterprise databases (Oracle, MySQL, PostgreSQL up to 10TB) with zero downtime. We've completed 5,000+ migrations with a 99.95% success rate.
  • Created a React-based admin interface that gives operators real-time visibility into migration progress with custom visualizations and streaming updates. The interface made operations 20% more efficient and became the control center for managing complex migrations.
  • Designed the Node.js backend architecture using message queues for reliable service communication and PostgreSQL for persistence. Achieved 99.9% availability while reducing response times from 1.2s to 840ms (30% faster).
  • Integrated the full stack of cloud services—secure storage, serverless functions, monitoring, and networking—while building robust error handling with automatic retries and comprehensive logging that made debugging distributed issues much easier.
  • Established engineering practices including automated testing (90% coverage), CI/CD pipelines with security scanning, and extensive documentation. Production issues dropped by 35%, and new engineer onboarding went from 6 weeks to 3 weeks.

Senior Full Stack Developer

MailerLite

Key accomplishment

  • Built a real-time campaign analytics platform serving 100,000+ users in 130+ countries. Optimized the infrastructure for live updates across multiple servers, cutting data latency from 5 seconds to 2 seconds (60% faster).
  • Created a flexible drag-and-drop form builder with 50+ field types and conditional logic that shows or hides fields based on user input. User engagement increased by 70%, and customers could now build complex forms without developer help.
  • Designed the email processing pipeline using message queues and 12 specialized workers that handle 5 million+ messages daily with automatic error recovery. Improved targeting accuracy by 40% and reduced processing time by 55%.
  • Optimized database performance through systematic query analysis, strategic indexing, intelligent caching, and table partitioning. Response times improved from 850ms to 595ms (30% faster) under heavy load.
  • Built a robust RESTful API with OAuth authentication and rate limiting (1,000 requests/hour) that handles 50,000+ requests per minute during peak usage. Comprehensive testing (85% backend coverage) helped reduce production bugs by 45%.
