I build high-impact software products for real business problems. My work focuses on Next.js platforms, robust backends with PostgreSQL, and practical automation that saves time at scale.
SYSTEM PROJECTS
Built a resilient Stripe payment gateway in NestJS using event-driven architecture to handle webhook retries safely under load. The system acknowledges requests instantly, deduplicates events with Redis, and processes payment workflows asynchronously with BullMQ workers to prevent race conditions, dropped events, and cascading failures.
Integrated management platform for hotels and commercial organizations with admin workflows and analytics.
Training academy with structured learning paths, video hosting pipelines, and modern admin tooling.
Desktop control system for members, payments, subscriptions, and daily operations in one dashboard.
Production-minded commerce backend with JWT/OAuth authentication, product variants, carts, orders, cancellations, exchanges, and role-based access.
10-30x catalog throughput boost with pagination and resilient Redis caching after autocannon load testing.
n8n automation connecting the full ad pipeline from research to voice-over and video production, with stage-by-stage coordination.
WhatsApp approve/reject actions, automated Drive organization, and time tracking that removed the owner's manual coordination bottleneck.
