I build secure intelligent systems that survive real conditions.

From LLM security pipelines to autonomous drones and lab robotics, I design systems that think, adapt, and stay reliable under stress.

About

I did not inherit this path. I built it like a system: layer by layer.

I operate at the intersection of AI security, robotics, and systems engineering. My work ranges from interaction-level security for large language models to autonomous aerial platforms and real-time perception pipelines.

I care about one thing: reliability in environments that do not care about your assumptions. Drones in unstable air. LLMs with adversarial users. Lab systems that cannot afford ambiguity. I design for those conditions.

Systems I’ve helped build

Each project is a system, not a checklist of tasks.

Interaction-centric LLM Security Framework

A taxonomy and defense pipeline for dialogue-level vulnerabilities across input, processing, and output layers in LLM systems.

  • Interaction-chain taxonomy for conversation phases.
  • Defense pipeline with PISR, ILVI, DCR, UTCE.
  • Designed for IEEE-style security evaluation.

Autonomous Hexacopter Platform

Coaxial hexacopter on Navio2 & Raspberry Pi with lidar-based avoidance and mission logic built for real-world turbulence.

  • Sensor fusion with Garmin Lidar-Lite & TF Mini.
  • Mission-planner integration and telemetry stack.
  • Architecture meant for field reliability, not lab demos.

RealSense Vial Classification & Sorting

Vision pipeline that detects vial cap colors, empty slots, and missing caps, feeding directly into robotic actuation.

  • Intel RealSense perception with robust segmentation.
  • Deterministic outputs for ROS-based arms.
  • Designed for noisy lab environments.

Micro-Drone Optical-Flow & Multi-Ranger Logic

Stability and navigation behaviors for small drones on imperfect hardware using flow and range sensors.

  • Spiral search and blue-tape line following.
  • Obstacle-aware hover patterns.
  • Extracting stability from unstable airframes.

How I think about systems

My advantage is not a tool. It’s how the pieces are connected.

Interaction chains over single prompts

I treat LLMs and humans as interacting agents over time, not isolated queries. Failures usually live in the sequence.

Nature-inspired architectures

Swarms, ecosystems, and feedback loops influence how I design multi-agent systems, drones, and long-horizon AI workflows.

Safety before scale

Reliability is a design constraint, not an afterthought. If it cannot survive a hostile environment, it is not ready.

Execution over aesthetics

I care about systems that ship, fly, and recover from edge cases. Everything else is decoration.

Long-term vision

AI, robotics, and nature are not separate stories.

My long-term work aims to build intelligent systems that help preserve, understand, and regenerate ecosystems. Think of drones, sensors, and language models as one coordinated nervous system for the natural world.

I want to move from “systems that survive” to “systems that protect” – where every improvement in AI and robotics compounds into better outcomes for the environments we depend on.
