Behnam Rajabnezhad
Software Engineer building scalable products at the intersection ofWeb & AI
01About
Long before AI became part of every developer’s toolbox, I was already writing, debugging, and shipping software — line by line.
I’m Behnam Rajabnezhad — also known as B3hnamR — a Full-Stack Developer and Software Engineer with an M.Sc. in Software Engineering – Networks and more than seven years of professional development experience.
Today I combine that hands-on foundation with modern AI to build real-world products across frontend, backend, APIs, databases, infrastructure, automation, and intelligent systems — from web applications and backend services to AI integrations, Telegram bots, custom tools, and security-focused software.
I enjoy turning complex technical problems into scalable, practical, polished products. I’m fluent in English and at home in international, collaborative, and distributed teams.

Browser game · Arena shooter
Neon Arena
A fast, skill-first neon arena shooter that runs in the browser: roguelite runs, a hangar for meta progression between them, co-op for up to four pilots and 1v1 / 2v2 PvP. The server runs the real game headless at 60 Hz, so no one gets a host advantage — and every sound and sprite is generated in code.
Areas
Visit neonarena.ir- Vanilla JS + Canvas
- Zero dependencies
- Server-authoritative co-op
- Headless 60 Hz simulation
- Client prediction & lag compensation
- PvP (1v1 · 2v2)
- WebSockets
- Procedural audio (WebAudio)
- Leaderboards
- PWA

04Experience
Seven years,line by line.
7+years of professional software development
My programming experience predates the AI-assisted era — so today’s tools amplify a foundation that was built by hand.
- L1
Foundation
Writing the code, debugging the problems, designing the architecture — figuring things out line by line, before AI was part of the toolbox.
- L2
Systems
Backend engineering, API design and databases — plus the infrastructure, deployment and networking that keep it all running, built with security in mind.
- L3
Intelligence
Today that foundation meets AI: LLM integrations, AI systems and automation woven into real-world products — along with Telegram bots and tools that get work done.
