Introduction
Job Highlights
Co-founder & Technical Lead
Co-founded Simanban.com — Iran's first AI-powered B2B platform digitizing the physical cement and concrete trade market, expanding sales reach from a single city to a nationwide marketplace. Engineered a data pipeline to collect, clean, and categorize large volumes of raw physical market trade data, presenting it through a high-quality analytics dashboard. Built an AI-powered chat interface that converts natural language questions into sophisticated database queries. Digitized manual cement sales and expanded to concrete — shipping a driver mobile app, sales management dashboard, and affiliate marketing system that drove a ~30% increase in overall sales. Launched at the International Cement Exhibition — acquired 500 bulk and tower builder users within the first hours. Led a team of 3, owned full architecture and CI/CD pipelines.

Senior Software Engineer
Built the backend for AuraDent's multi-clinic dental booking platform using NestJS and a microservices architecture orchestrated via Kong API Gateway, deployed on Kubernetes (K8s) with zero downtime in production. Solved the core sync challenge of aggregating appointment data from multiple third-party clinic booking systems — implemented an event-driven architecture with the Outbox Pattern and eventual consistency. Prevented double-bookings under high concurrency using Redis Redlock (distributed lock) combined with database-level optimistic locking. Secured sensitive patient data with end-to-end encryption and centralized secrets management (HashiCorp Vault).

Senior Backend Developer & AWS Cloud Architect
Built and maintained REST API endpoints for a fintech copy-trading platform using Express.js, MySQL, and Prisma ORM. Architected a high-scalability trade broadcasting system using AWS SNS + SQS fanout pattern — a single leader trade signal fans out to trigger simultaneous copy orders across thousands of follower accounts with guaranteed, no-loss delivery. Built WebSocket connection management on AWS API Gateway + DynamoDB handling full connection lifecycle for real-time market and account updates. Implemented AWS Lambda serverless workers and Step Functions for multi-step workflows — reduced Binance historical data generation time by 90%.

Backend Developer
Built microservice REST APIs for a blockchain-powered cryptocurrency exchange platform using Domain-Driven Design (DDD), supporting Investor Launchpad, Innovation Forge, and Digital Evolution Hub products. Designed and implemented a Central Limit Order Book (CLOB) matching engine using Price-Time Priority (FIFO) algorithm — ensuring fair, low-latency trade execution. Built a market maker bot to provide liquidity by continuously placing bid/ask orders around the mid-price. Integrated with multiple blockchain full nodes (BTC, ETH, BNB and others) achieving 100% transaction reliability; reduced API latency by 80% via Redis caching layer.
