Projekthistorie
Led a 6-engineer team building a high-load SaaS CRM/ERP platform for 100k+ concurrent users using Laravel, React, PostgreSQL, Redis, Docker, and RabbitMQ. Architected the platform from scratch, integrated 10+ third-party services, and reduced page load from 60s to under 1s, DB load by 65%, and boosted throughput by 200%+.
Developed a CRM platform with real-time analytics using Symfony, FastAPI, React, Vue.js, PostgreSQL, Redis, and WebSockets. Built CRM/analytics modules, delivered real-time WebSocket chat and live dashboards, improved API response time by 40%, and reduced SQL query time by 50% via multi-layer Redis caching.
Developed high-load promotional platforms with payment and external API integrations using Laravel, Drupal, Python, MySQL, Redis, and Docker. Sped up background job processing by 70% and tuned systems for traffic spikes and peak-load stability.
