Reza Pirighadim

Senior AI Engineer & Backend Architect

I build scalable backends and production-grade agentic AI — systems that don't just demo well, they ship and stay up. Eleven years across crypto exchanges, marketplaces, accounting platforms, and now multi-agent AI.

01About

A backend mind learning to think in agents.

I've spent eleven years writing the unglamorous half of software — the part that runs at 3 AM and doesn't make the front page. Order systems, identity services, exchange engines, billing, message queues. The infrastructure that lets the visible app exist.

Lately I've been turning that backend instinct toward agentic AI: multi-agent systems coordinated with LangGraph, retrieval pipelines that don't hallucinate, event-streamed orchestrators on Redis and SSE, and tool-using agents wired through the Model Context Protocol. The same questions still apply — is this observable, is this resumable, does it stay correct under load — they just have new answers.

I'm comfortable owning a system from architecture through production, and I've led teams as both a technical lead and a senior engineer at companies like Digikala, Wallex, and Holoo.

Eleven years, in chronological reverse.

  1. 2026 — Now2 months

    Senior AI Engineer

    Jack Westin · Remote · United States

    Building an AI-driven student assistant that answers course-specific questions with the precision a tutor would. Wired up RAG over the curriculum to keep hallucinations near zero, and iterate with the education team to keep responses pedagogically sound — not just technically correct.

    AI Engineer

    Alien Intellect · Remote · UAE

    Architected a production multi-agent system on a supervisor pattern — five specialized agents (Orchestrator, Knowledge, Developer, Operator, Generator) coordinating autonomous task execution. Real-time event streaming via Redis Streams & SSE, checkpoint-based persistence in Postgres, async pipeline on Celery, and human-in-the-loop interrupts so the system can pause, ask, and resume cleanly.

    Technical Lead

    DrBalcony · Remote · California

    Designed the enterprise user-management system that became the platform's central auth and authorization hub — every microservice talks to it for identity, permissions, and access control. Built to take enterprise-scale load while keeping inter-service comms fast and the security model fine-grained.

    Senior Software Engineer

    Digikala · Hybrid

    On the Pindo shop team: rewrote and optimized the seller-side delivery system, owned OMS messaging, and shipped the integrated digital wallet. Crossed teams to plug into the AI org's image-search system for ad creation — bridging traditional e-commerce ops with newer AI capabilities.

    Senior Backend Developer

    Wallex · Hybrid · Crypto Exchange

    Built secure, high-throughput trading paths for a major crypto exchange. Sped up order execution, led Exchange and Onboarding initiatives, and rebuilt the registration flow that drove a measurable lift in user acquisition. Ops-grade work — every millisecond and every error counted.

    Technical Team Lead · Senior Backend Developer

    Holoo Software · Tehran

    Led teams architecting accounting and ERP applications used by thousands of Iranian businesses. Set the technical direction, mentored engineers, and owned the backend architecture end-to-end — performance, DB design, and the integrations that kept front-end and back-end in sync.
