AboutMe

I build software where reliability matters, decisions have consequences, and the product has to hold up outside a demo.

Over the last 6+ years I've worked across fintech, healthtech, and cybersecurity, moving between backend systems, platform architecture, product delivery, and the practical realities of shipping software people depend on.

Right now I'm focused on cybersecurity systems at CounterShadowwhile pursuing a Master's in Computer Science. The common thread through all of it is simple: build cleanly, think long-term, and make sure the thing actually works when conditions stop being ideal.

What I Tend To Build

Secure financial systems and payment workflows
Healthcare products with real user and compliance constraints
Cybersecurity automation, incident response, and platform tooling
Full-stack products from early concept to deployed system

How I Work

I care about the gap between a prototype that looks convincing and a system that survives real traffic, real users, and real operational pressure.

That means I naturally gravitate toward durable architecture, clear domain modeling, security-minded design, and product decisions that make technical work easier to extend instead of harder to maintain.

I like working where engineering quality and product usefulness have to coexist, not compete.

Beyond The Code

Outside work, I'm usually in the gym or experimenting in the kitchen. Both scratch the same itch as engineering: discipline, repetition, refinement, and the satisfaction of getting small details right.

Software Engineer - AI Security & Autonomous Incident Response2025active
CounterShadowJanuary 2025 - Present - Remote, London UK
CounterShadow is an autonomous cybersecurity incident response platform built to investigate and respond to security incidents without waiting for a human to act. I work across the core systems that make that possible.CounterShadow
AMI Responder - built an ephemeral, containerized AI agent that autonomously investigates security incidents from the moment an alert fires. It collects evidence, reasons through what it finds, and produces a documented response without human intervention unless you want it to pause and ask.CounterShadow
Security Playbook Infrastructure - engineered support for CACAO v2, the OASIS standard for machine-readable security workflows, giving security teams a structured way to define and execute incident response logic through the platform.CounterShadow
Agent Memory Architecture - built a hybrid knowledge store combining a graph database and vector search, so agents can build on investigative context across the lifetime of an incident.CounterShadow
Platform Backbone - built alert ingestion pipelines (webhooks, syslog), distributed action execution infrastructure, third-party security tool integrations, and the authentication and RBAC layer the whole platform runs on.CounterShadow
