🏆 15+ Years of Experience Building Production SaaS Platforms I build scalable SaaS platforms that power real businesses—not demos or prototypes. My expertise is designing backend systems that continue to perform as products grow: more customers, more integrations, more data, and more automation. Whether it's a complex CRM, an AI-powered support platform, or a high-load API service, I focus on building software that is reliable, maintainable, and ready for production. 🚀 Large-Scale SaaS Experience One of my largest projects is SMMQuest, a SaaS platform that connects 2,500+ external providers through a unified API architecture. The platform handles: ✔ Thousands of orders daily ✔ Millions of API requests ✔ Real-time synchronization across multiple providers ✔ Intelligent order routing and failover ✔ Payment gateway integrations ✔ Live dashboards and reporting Building this platform required solving challenges around scalability, reliability, distributed APIs, and automation under continuous production load. 🧠 AI Engineering Recently, I designed and developed an AI-powered customer support platform for an eCommerce company operating multiple brands. The system was built using: ✔ 20,000+ Zendesk support tickets ✔ Product documentation ✔ Internal business knowledge ✔ Historical customer conversations Instead of building a simple chatbot, I designed the complete AI backend architecture, including: ✔ RAG (Retrieval-Augmented Generation) ✔ Knowledge ingestion & document processing ✔ Embedding generation ✔ Vector database architecture ✔ Semantic search & retrieval ✔ LLM orchestration ✔ Response evaluation and quality improvement I also developed a Chrome Extension that enables support agents to retrieve similar solved cases and generate AI-assisted replies directly inside their workflow. The architecture was designed to support future multi-tenant AI assistants, company-specific knowledge bases, human feedback loops, and AI performance analytics. 💼 What I Build I specialize in backend systems where scalability and business logic matter.
