AI Developer @ University of Warwick. Applied AI, LLMs & Agentic Systems.

I build systems that stay up.

Software engineer working at the intersection of applied AI and production infrastructure. I work part-time and remotely as a Graduate AI Developer at the University of Warwick, where I research LLM architectures, design agentic systems and automate internal workflows; across 5+ years before that I shipped systems for 100+ UK businesses, from architecture through CI/CD to deployment on Docker, Linux and Go.

01 About & Core Highlights

Applied AI · Uptime · Migrations · Low-Latency Systems

I work on the parts that are hard to fake.

Research that has to survive contact with real users, and systems that have to stay up while you change them underneath. The unglamorous middle ground between a promising idea and something a team can actually depend on.

  1. 01 PRODUCTION PROOF

    Applied LLM research

    At the University of Warwick I investigate model architectures and evaluation methods, turning early-stage research ideas into working prototypes the team can actually test and adopt.

  2. 02 PRODUCTION PROOF

    Agentic engineering at scale

    I design and ship agentic LLM systems — tool-using agents, retrieval pipelines and workflow automation — that take repetitive internal processes off people’s plates and make them reproducible.

  3. 03 PRODUCTION PROOF

    Solution architecture

    I take ambiguous requirements and turn them into concrete system designs: model selection, data flow, evaluation strategy and the infrastructure to run it reliably.

  4. 04 PRODUCTION PROOF

    Restaurant ecosystem at scale

    I maintain a full restaurant management system, including POS and customer ordering, and orchestrated the migration of that legacy Laravel monolith for 100+ UK restaurants from v5.6 to v12 with zero service interruption.

  5. 05 PRODUCTION PROOF

    Infrastructure engineering

    I replaced a third-party Pusher dependency with a custom Go real-time engine I built from scratch, which cut infrastructure costs and noticeably lowered latency.

  6. 06 PRODUCTION PROOF

    Zero-downtime migration

    I led a high-stakes migration of over 1.4TB of production data using rsync, holding 100% data integrity with absolutely no downtime.

  7. 07 PRODUCTION PROOF

    Automated media pipelines

    I developed a custom FFmpeg pipeline in PHP that integrates with the Discord API to fetch videos, transcode and crop them for compatibility, and securely store the results in AWS S3.

  8. 08 PRODUCTION PROOF

    Payment systems

    I designed and deployed a multi-currency subscription system on Stripe, fully tested and reliable for global transactions.

  9. 06 OPERATING PRINCIPLE

    End-to-end ownership

    From schema design and application code in PHP/Go to Dockerized CI/CD pipelines, Linux kernel tuning, and zero-downtime cutovers.

02 Production Experience

6 Roles · University · Agency · Consultancy

Five years of production, now in applied AI.

Currently a part-time, remote Graduate AI Developer at the University of Warwick, researching LLM architectures and building agentic systems — alongside five years of shipping production software across the UK, Canada, the US and Bangladesh.

03 Selected Systems & Open Source

Agentic LLM · OS Auth · Linux Systems · Real-Time Go · Rust Desktop

Things I built because the alternative was worse.

Each of these started as a real constraint — a bill that was too high, a library that didn't exist, a latency budget that couldn't be met.

01

University of Warwick · Applied LLM / Agentic Systems

Agentic Workflow Automation

  • Designed agentic LLM systems that plan, call tools and orchestrate multi-step tasks against real internal data.
  • Built retrieval pipelines so agents ground their answers in source material rather than relying on model memory.
  • Developed evaluation harnesses to compare architectures, prompts and models against measurable task outcomes.
  • Automated internal team workflows end to end, removing manual handoffs from recurring processes.
  • Worked as solution architect: scoping requirements, choosing models and data flow, and defining success criteria before building.

Linux Authentication · Computer Vision / OS Security

  • Face unlock for Ubuntu — Windows Hello, but open source: look at the camera and you are in.
  • Built a PAM module (pam_openface.so) that intercepts the login prompt and delegates to a background auth service, falling back to password on failure.
  • Integrated InsightFace/ArcFace recognition with optional IR-based liveness detection to resist photo and video spoofing.
  • Shipped a full CLI for enrolling faces, checking service status and testing authentication end to end.

Linux Systems · AI Virtual Webcam

  • AI-powered virtual webcam daemon that turns a real camera into /dev/video10 with auto-framing (crop and follow your face).
  • On-demand lifecycle: the physical camera is only opened while an application is actually watching the virtual device.
  • Engineered for weak CPUs — threaded capture, downscaled and skip-frame landmark detection, reused NumPy buffers and per-frame cost logging.
  • Ships as a self-contained 164MB bundle (Python + OpenCV + NumPy + MediaPipe embedded), so a target machine needs only a kernel that can run the v4l2loopback module.
  • Idempotent installer wires up the kernel module, a systemd --user unit and a GNOME Shell extension, needing sudo only for the module step.

Applied LLM · Network Automation Agent

  • Conversational CLI agent that turns plain English ("harden SSH on this router") into ready-to-deploy Cisco IOS commands.
  • Combines Netmiko SSH automation with an LLM to generate the how from a described what, occupying a gap no existing tool (Ansible, NAPALM, Nornir) fills.
  • Human-in-the-loop command editor lets engineers review, edit and approve every command before it is pushed to a device.
  • Secure, auditable sessions with configuration backup and session logging; operates in privileged EXEC mode by default.
  • Validated across ten real-world use cases spanning OSPF, VLAN provisioning, NAT, ACLs and compliance auditing.

Desktop App · Rust / Tauri

  • Lightweight Linux dashboard and tray indicator for managing local DDEV projects — see what is running at a glance.
  • Start, stop and restart projects with in-progress feedback, and quick-launch the site, Mailpit or project folder.
  • Tray icon summarises how many projects are running, with a quick menu to control them without opening the window.
  • The app never talks to Docker directly — it shells out to the ddev CLI and parses JSON, keeping DDEV the single source of truth.
  • Desktop notifications, run-in-background, and optional start-on-login minimised to the tray.

Vision-Language Model · Llama 3.2 Vision

RadInsight

  • Fine-tuned the 11B Vision-Instruct model using LoRA.
  • Trained on 750,000+ radiology image-text pairs (MIMIC-CXR, CheXpert).
  • Built a WhatsApp-based automated report delivery system with 15–30 second response times.
  • Optimised training on an RTX 3060 under 12GB VRAM.

Real-time messaging server

  • A Go-based real-time WebSocket server built as a lightweight, self-hosted alternative to Pusher.
  • Implemented connection pooling and webhook handling for production workloads.
  • Optimised for low-latency broadcasting in single-tenant environments.
08

Bengali transliteration engine

  • High-performance Avro Phonetic library that converts Banglish to Bengali script, with Trie-based pattern matching for O(m) lookups instead of linear search.
  • Context-sensitive rule engine that resolves conversion intelligently based on surrounding characters.
  • Laravel-ready with auto-discovery, a Facade and config publishing — and standalone-compatible with any PHP project.
  • Covered by 180+ tests and compatible from PHP 5.6 through 8.x.
