Agent security & applied AI

Aahil Shaikh

I build agents that remember what they’ve done, and the security layer that decides what reaches them. One at TwelveLabs, one on hardware I own.

Sophomore at Texas A&M · Two terms at TwelveLabs · Dublin, CA

Trajectory Every job I’ve had was caused by the one before it. Drawn as the thing it actually is.

What I shipped

Feb – Jun 2026 · TwelveLabs · Shipped to beta

Electra

An internal AI agent built on top of the company’s IT ticketing system. I owned most of the implementation alongside my manager, and shipped it to beta before my term ended.

Internal tool — no public repo.

Memory
Every conversation, interaction, and thought links into a graph-based knowledge network — prototyped in Obsidian, then migrated to GBrain, our internal graph memory. Context persists across sessions and the reasoning stays traceable.
Defense
Hardened against prompt injection, jailbreaks, and token-bomb exploits: rate limiting, input sanitization and validation, RBAC-style permissions, and anomaly detection with logging.
Next
Designed the foundational architecture for a Hermes-style self-learning structure, so agent behavior improves on its own over time.

Aug – Dec 2025 · TwelveLabs

SAGE

A full-stack tool for comparing video assets. Runs Marengo embeddings through cosine similarity over 2-second segments, across a 1024-dimensional space.

  • Embeddings
  • Similarity search
  • Full-stack

Recurser

My proposal, then my ship. Analyzes AI-generated video, refines the prompt, and runs it again — each pass closer to the intent.

  • Prompt engineering
  • Iterative systems

Jockey

Bug fixes and feature work on the conversational video agent built on Marengo and Pegasus.

Bastion

A real-time security dashboard for live HTTPS video streams. Pushed monitoring past the fixed-length-video workflows the platform assumed.

  • Real-time video
  • Monitoring

Mar 2025 · Chinatown Hacks

Sentinel

An AI security application on the TwelveLabs API. Started as a hackathon prototype, became a one-week technical project, then became the internship.

Density tracker

Real-time population density with YOLO detection and custom rasterization. Vector-to-bitmap conversion means the data can never carry a face out with it.

  • YOLO
  • Rasterization
  • Privacy by design

On my own time

  • MAGI

    A multi-agent system on hardware I own, with no cloud in the path. An orchestrator scores each task for complexity, picks a local model to match, and hands it to the agent for that domain. Every task clears a security assessor first — 35+ patterns for prompt injection, jailbreaks, and system-prompt extraction, graded safe through critical, where a hit either downgrades the model the task is allowed to reach or blocks it outright.

    Private

  • clair

    My Claude Code environment as code. One dependency-free Python tool rebuilds the whole setup — settings, hooks, commands, skills, plugins — on a fresh macOS, Linux, or Windows machine, and re-running it converges to the same state. Anything personal or secret lives in a private overlay and never touches the public repo. MIT, installs from a Homebrew tap.

    Published GitHub ↗

  • UFW Manager

    A Python tool that makes UFW firewall rules bearable — add, remove, and list IP bans without the ceremony. Published to my PPA, so Ubuntu installs it straight from apt.

    Published GitHub ↗

  • FlashGuard

    Watches USB storage for unauthorized access and malware, and stops the transfers you didn’t ask for.

    In progress GitHub ↗

  • Mailsmith

    Give it a prompt, get a written email, sent through the Gmail API to the person you meant.

Path

How it went

  1. Feb – Jun 2026

    Software Engineering Intern — Agent Security & Internal Tools

    TwelveLabs

    Came back for a second term, this time pointed squarely at agent security and applied AI architecture. Led Electra end to end and proposed features past the original scope. Shipped to beta.

  2. Jun – Dec 2025

    Software Engineering Intern — DevEx

    TwelveLabs

    Built SAGE, Bastion, and Recurser, and contributed to Jockey. Ran live demos, made product and UX calls, and wrote the docs and blogs that explained it all. The internship was extended from three months to six.

    College Station, TX · Sophomore · 4.0 GPA

  4. Mar 2025

    Avionics Lead

    Blinn Propulsion Laboratory

    Owned avionics end to end — design, integration, and the troubleshooting at 2am — with directors rather than over my shoulder.

  5. Mar 2025

    Chinatown Hacks

    Participant

    Presented to a judging panel and to sponsors from TwelveLabs. Left with a site-visit invitation, which turned into everything above.

  6. Aug 2024 – Mar 2025

    Manager & Co-Lead

    Circuit Bakers FRC

    Took a rookie team to competition standard. Managed a sub-team of 10, co-led finances, ran mechanical, and programmed.

  7. Jun – Aug 2024

    CS61A

    UC Berkeley Pre-College Studies

    Eight weeks on campus in Structure and Interpretation of Computer Programs — recursion, abstraction, inheritance, and the habits that stuck.
