Work Experience

Intelligent Processing of Pars Hadish - 2023-Present

• Stack: Go, Python, FastAPI, PostgreSQL, MongoDB, ClickHouse, Redis, RabbitMQ, WebSocket, Docker

B2C Tourism Platform

• Took over a tourism platform (3M+ users, 9+ B2B partners) that had run without a developer for months, learned the codebase and the business rules unaided, and now own it as tech lead with a team hired around it: payment routing to per-account settlement terminals and a reconciliation system of 3 interacting state machines for automated and manual mismatch resolution.
• Built corporate benefit-card contracts (quota- or balance-based entitlements per employee) and a multi-case refund engine (discount codes, disability subsidies, corporate credits); redesigned DB connection lifecycle and Redis caching to sustain 50,000 concurrent peak users.

Payment Gateway

• Built and own the production payment layer, in two independent implementations for two separate teams: Python/FastAPI and Go. Every provider sits behind one fixed 6-endpoint contract (make/verify/reverse plus open/approve/cancel), so adding a gateway never changes calling code; Redis distributed locking and idempotency guarantee exactly-once capture. 5 integrated gateways; the Go build is used by two Shiraz municipal projects.

Audit Log Service

• Built and own a tamper-evident audit log service in Go, from design through production: per-source HMAC-SHA256 hash chains — each connected backend has its own independent chain — a Redis Streams → ClickHouse high-throughput ingestion pipeline, and an emergency mode with disk monitoring and automatic log rotation.

Nekisa — Building Management & Security Monitoring

• Backend lead on a building management and security platform running 4,500+ IoT devices (cameras, access control, barriers) in production at Atlas Mall Tehran and Shiraz Metro, where RabbitMQ device streams drive a configurable scenario engine — surfacing a zone’s cameras the moment a door opens.
• Took over as sole backend engineer on this long-running production system and integrated several new device types, including camera tamper detection that stores the shock-wave signal and a snapshot when a unit is physically disturbed; now hardening the platform toward a formal security certification.

Meter Data Management System

• Inherited an unfinished, unstable Go backend after the previous developer was let go, stabilised it, built out the remaining features, and launched it: meter data collection and a multi-tier billing engine that generates detailed PDF invoices.

Real-Time User Analytics System

• Built a high-throughput analytics system with a visual Journey Builder to automate personalized user flows, engagement triggers, and A/B tests; powered by FastAPI, ClickHouse, and RabbitMQ.

Messaging System

• Built and own a priority-managed notification system (SMS & Push) on Redis Streams, serving real-time queuing across services.

Real-Time Taxi POS Backend

• Designed and built a WebSocket-powered system for real-time POS payments and live location streaming, then extended it with the team as it grew, adding operational reporting.

AI-Powered Supermarket Agent

• Built and own an automated shopping assistant for WhatsApp, live in production: users order by voice or text while the agent handles product search, cart state across a long conversation, and order creation.

Atishahr Smart City Iranians (Atishahr) - 2022-2023

• Stack: Python, FastAPI, PostgreSQL

SIB Ticket System

• Optimized a key reporting endpoint, achieving a 20x performance improvement and eliminating slowdowns under high load.
• Contributed to the project’s second version using FastAPI, implementing asynchronous features to handle increased system load.

Mehr-e Pars ICT (Mehr Pars) - 2021-2022

• Stack: Python, FastAPI, PostgreSQL

Organizational Resource Management System

• Engineered a data migration solution, enabling seamless transitions from legacy project management systems to the Rainesh platform.

Comprehensive Warehouse System

• Developed a load-simulating reverse proxy module for a large-scale warehouse system, simulating backend conditions under high load to improve frontend stability.

Open Source

• PyRemote (265 stars, 68 forks), An educational security-research framework in Python for exploring remote-control patterns over a chat transport.
• Muxr, A Go WebSocket multiplexing library for efficient real-time communications.
• IP, A Go TCP server that returns the client’s IP and country in multiple formats.
• PriceBot, A Go Telegram bot providing real-time currency exchange rates, gold prices, and cryptocurrency values.
• Social Token Experiment, A minimalist ERC-20 social token on Polygon, designed as an experiment in on-chain communication (Solidity).

Technical Skills

• Languages: Go, Python, Solidity
• Frameworks & Protocols: FastAPI, Gin, REST, WebSocket
• Databases & Caching: PostgreSQL, MongoDB, ClickHouse, Redis
• Messaging & Streaming: RabbitMQ, Redis Streams
• Architecture: Distributed systems, microservices, event-driven design, high concurrency, idempotency
