Backend & Systems Engineer · Bellevue, Washington

🙏 Namaste,

I’m TJ

I build backend and systems software for places where latency, reliability, and real-world constraints matter.

My work covers real-time systems, robotics, and distributed backend infrastructure.
I’ve worked on teleoperation over spotty LTE/4G networks, event-driven sensing for autonomous systems, and production backends that had to stay dependable amid scale, noise, and unexpected failures. I work across C++, Python, and cloud infrastructure, always prioritizing observability, resilience, and top-notch performance.

I love creating systems that remain calm and collected, no matter how chaotic the world around them gets.

Projects

Projects grounded in real systems problems.

A few things I’ve built around observability, reliability, robotics, simulation, and software that has to behave well under real constraints.

AI Security

Flint

A session firewall for MCP-connected agents. Enforces RBAC - roles, bindings, scopes, and per-argument constraints - then tracks data flow across calls to catch exfiltration attacks that per-request inspection misses.

Research

My research sits at the intersection of autonomy, resilience, and security.

I’m especially interested in autonomous systems that have to keep working under latency, packet loss, adversarial conditions, and real-world uncertainty and in the cryptographic systems that make trust possible in distributed environments.

Autonomous Systems & Robotics

Low-latency autonomy under adversarial conditions

I work as a Research Engineer with Prof. Sibin Mohan at George Washington University, focusing on autonomous drones and rovers with an emphasis on secure, low-latency communication and system resilience.

  • Multi-agent coordination and telemetry
  • Security in adversarial environments

Current Focus

Failure detection, protocol weakness, and mitigation

My current work looks at how autonomous systems degrade before failure becomes obvious - from memory-safety issues in drone communication stacks to protocol-level weaknesses in onboard and ground-station interfaces, and real-time detection and mitigation of adversarial behavior.

The goal is to improve the safety, robustness, and reliability of autonomous systems operating in hostile or unpredictable environments.

Blockchain & Cryptography

Privacy-preserving and decentralized systems

I also have a research background in cryptography and decentralized systems, with a focus on privacy-preserving technologies such as zero-knowledge proofs.

  • Elliptic curve cryptography
  • Smart contract vulnerability analysis
  • Privacy-aware system design
Publications & Talks

Writing and teaching technical ideas clearly

I co-authored Blockchain for Beginners: Art of Decentralization and Cryptography, a foundational text on cryptographic primitives and decentralized systems.

I’ve also delivered talks and workshops on blockchain and cryptography at conferences and technical meetups.

Beyond work

A few things about me.

The work matters, but so do the things that shape how I think, what I notice, and what I end up obsessing over.

Curiosity

Formula 1, systems, and engineering rabbit holes

I’m drawn to things that look elegant from a distance and get complicated up close - Formula 1, control under constraint, aircraft geometry, and the engineering decisions behind systems that somehow work as well as they do.

Language

Poetry and Farsi

I write poetry, and I’m learning Farsi. Language sharpens the same instincts I use in engineering: structure, ambiguity, rhythm, and precision.

Thinking

Best thinking happens in motion

I like long hikes, road trips, and karting. Nature and speed usually help me untangle problems that refuse to move at a desk.

Art

Digital art and sketching

I sketch digitally when I want to think with my hands instead of code. It’s a different kind of problem-solving - slower, quieter, and a good reminder that not everything interesting needs to be optimized.

Books

Reading outside the screen

I like books that make me think differently about systems, people, and perception. Reading helps me step out of the immediacy of engineering and come back with better judgment.

I’m open to roles where the work is thoughtful, difficult, and real.

Backend, systems, and robotics roles are the best fit. I’m especially interested in teams working on real-time systems, resilient infrastructure, autonomy, observability, or software that has to operate under real constraints.

If that sounds close to what you’re building, I’d be glad to talk.
