About

I build backend systems that scale — and increasingly, systems that think. Backend Developer with 3.5 years of production experience building scalable APIs, microservices, and AI-powered applications across fintech and edtech domains. At Bright DiGi Gold, I designed and deployed 25+ RESTful APIs using Node.js and Express.js, handling 10,000+ daily transactions. Optimized MongoDB and MySQL queries through indexing and schema redesign — achieving a 30% improvement in query execution speed. Containerized and shipped services on AWS using Docker, reducing release cycle time by 20%. Beyond core backend work, I've integrated OpenAI and Anthropic APIs to build AI-powered features and Retrieval-Augmented Generation (RAG) pipelines — enabling intelligent document search and context-aware responses over private business data. I've also designed and deployed SMTP-based email infrastructure for internal office workflows, covering templating, routing, and delivery reliability end-to-end. I write clean, testable code, contribute through Git-based code reviews, and work well across cross-functional teams — consistently delivering projects on time with high stakeholder satisfaction. What I work with: Node.js · Express.js · Java Spring Boot · Python (Django, Flask, FastAPI) · React.js · TypeScript · MongoDB · PostgreSQL · AWS · Docker · OpenAI API · Anthropic API · RAG · SMTP Currently open to backend or full-stack engineering roles at unicorns, MNCs, and high-growth startups. 📩 iaryato@gmail.com
