Senior Software Engineer with 6+ years of experience designing scalable software across AI, robotics, distributed systems, and modern web platforms. Experienced in leading architecture, modernizing engineering systems, and delivering production-ready solutions.

01. About

Building systems that matter

I'm a Senior Software Engineer based in Tehran, Iran, with a strong passion for solving complex engineering challenges at the intersection of AI, distributed systems, and modern web platforms.

Over the past 6+ years, I've led the development of end-to-end AI pipelines for medical imaging, modernized shipment visibility platforms used globally, and engineered mission-critical robotic automation systems for pharmaceutical manufacturing.

I thrive in environments where engineering rigor meets product thinking — driving architectural decisions, mentoring teams, and shipping production-ready solutions that create measurable business impact.

Currently pursuing a Master's in Artificial Intelligence at Azad University (IAU), deepening my expertise in ML systems and computer vision.

04. Projects

Open Source & Hobby

Side projects I build to explore ideas, teach concepts, and sharpen tools I care about — from protocols and databases to visual computer vision workflows.

Image Pipes

124

Stop scripting. Start seeing.

Build computer vision pipelines visually — inspect every pixel transformation in real time, then export clean, production-ready Python the moment you're happy with the result. Assemble your pipeline as a graph, watch every node's output update live, and walk away with production code — not a black box.

  • Visual graph editor for computer vision pipelines
  • Live per-node output inspection while you tune parameters
  • Breaks the tweak → run → save → squint debug loop
  • Export production-ready Python when the pipeline looks right

Wireflow

Interactive network protocol playground

Learn how REST, streaming, SSE, WebSocket, gRPC, polling, GraphQL, WebRTC, MQTT, and more move data between clients and servers. Everything runs in the browser — step animations, failure scenarios, side-by-side compare, and a short chooser quiz. No accounts or live traffic.

  • Step simulator with play/pause, speed control, and looping packet motion
  • Failure scenarios: timeouts, reconnects, rate limits, ICE failure, and more
  • Comparison table and dual-protocol compare derived from protocol traits
  • Protocol chooser quiz — three questions → recommended protocol
  • Shareable deep links like #websocket/happy/3 or #rest/rate-limit/1

DataFlow

Interactive database learning path

Start with SQL fundamentals, then internals and families, and finish able to choose a storage architecture for workload and guarantees — and grow from a handful of requests to billions. Everything runs in the browser: leveled lessons, Mermaid diagrams, concept simulators, a workload chooser quiz, side-by-side compare, shareable deep links, and local progress. No accounts required.

  • Seven levels — Beginner → Intermediate → Advanced → Distributed → Data architecture → DB engineering → Architect
  • Lesson reader with prose, SQL examples, ASCII + Mermaid diagrams, and takeaways
  • Concept simulators for Postgres path, transactions, replication, polyglot, and more data models
  • Database chooser starting with “why not PostgreSQL?”, then adaptive questions → engine + checklist
  • Comparison matrix, localStorage progress, quick find (Ctrl/⌘ K), and deep links like #beginner/joins
