Hi 👋 I'm Amir Abbas Ranjbar

Senior Software Engineer • Distributed Systems • Cloud Platforms

Building scalable backend systems that process millions of events reliably



🚀 About Me

I'm a Senior Software Engineer focused on designing large-scale backend systems and distributed architectures.

Over the past 8+ years, I have built systems capable of handling:

hundreds of thousands of transactions per hour
millions of streaming events
high-traffic production platforms

I enjoy transforming complex business challenges into scalable technical platforms.

Currently building AI-powered hospitality platforms and smart-building systems while experimenting with AI-assisted engineering workflows.

I believe software architecture is like music:

architecture is rhythm
services are instruments
distributed systems are orchestras


🏗 Systems I've Built

⚡ Real-Time Catalog & Pricing Engine

Designed a streaming architecture processing 2M+ product updates per minute using:

Kafka
Apache Flink
Microservices architecture

This replaced a 30-minute monolithic sync pipeline with real-time streaming.


🎮 High-Traffic Gamification Platform

Built a campaign system supporting:

250,000+ daily orders during national campaigns

Architecture:

ASP.NET Core Microservices
Kafka Event Backbone
Real-time reward orchestration


🏨 Smart Hospitality Platform

Co-founded and architected a BPMS-driven SaaS platform for:

• hotels
• residential complexes
• office buildings

The platform automates operational workflows such as:

facility management
accounting processes
internal service management


✈ AI Trip Planner

Developed an AI-powered tourism assistant that enables hotels to generate personalized travel experiences for guests.


🧠 Engineering Philosophy

Build systems that scale without drama
Prefer event-driven thinking
Optimize for reliability and observability
Design for evolution, not perfection
