01 — About

Engineering for systems that can't afford to fail.

I'm a Full-Stack & AI Engineer with over two years spent building software where correctness and security aren't optional — cybersecurity platforms that detect threats in real time, AI-driven tools that turn unstructured data into decisions, and cloud backends that hold up under production load.

My work sits at the intersection of three disciplines: secure backend architecture, applied AI, and modern frontend engineering. I care as much about a clean threat-detection pipeline as I do about the interface a security analyst actually has to use at 3am.

I work end to end — from data model and API design through to the interactions a user finally touches — and I default to building systems that are observable, permissioned correctly, and built to scale from day one.

Five systems. Five domains. One engineering standard.

Each project shipped as a complete product — architecture, security, and interface treated as one problem, not three.

SECURITY OPERATIONS

SIEM / XDR Cybersecurity Platform

AI-driven threat detection at production scale

A modular detection-and-response platform for Neoxion Technologies — microservices orchestrated with Docker Compose, a React/Ant Design console for hosts, agents, and alerts, and a self-healing Go agent handling automated deployment in the field.

  • Kafka Connect streaming security events into OpenSearch, normalized to ECS format for threat detection across 1,500+ Sigma rules
  • 17 Random Cut Forest anomaly detectors mapped to MITRE ATT&CK techniques for real-time coverage
  • Internal PKI on RSA 4096 with mutual TLS securing every service-to-service connection
  • Self-healing Go agent (Sysmon/Winlogbeat) using one-time tokens for automated WinRM deployment

AI / TALENT INTELLIGENCE

AI-Powered Web Application for Talent Search and CV Management

AI-driven talent search & CV management

Built during an internship at Proged Solutions — a full-stack platform on React and .NET Core with Azure Cosmos DB, designed to turn unstructured CVs into structured, matchable talent data.

  • Automated CV data extraction via Azure AI Document Intelligence
  • Skills-based employee-project matching system
  • Azure Active Directory and Microsoft Graph API integration for secure auth and automated user sync

Organization & Member Management

Multi-tenant workspace infrastructure

The invisible backbone that lets a company spin up its own secure workspace — organizations, invitations, roles, and permissions handled cleanly at scale.

  • Multi-tenant architecture isolating data and access per organization
  • Invitation and onboarding workflows with granular role management
  • Fine-grained, permission-based authorization across every endpoint

SOCIAL

Interactive Forum Social Platform

Interactive community platform

A social space built for conversation — groups, questions, polling, and real-time chat designed to keep communities engaged and connected.

  • Real-time chat and notifications powered by Appwrite's real-time backend
  • Group, question, and comment system with live polling
  • Modern, responsive interaction model tuned for daily active use

HEALTHCARE

Medical Appointment & Patient Management

Clinical operations, simplified

Built at King Digital YC — a Laravel (MVC) application covering the full patient journey, from online booking to staff scheduling, with access strictly scoped by role.

  • Online booking system with a staff calendar view for scheduling and consultations
  • Patient record and prescription handling with strict data boundaries
  • Role-based access control separating patients, medical staff, and administrators
  • Analytics dashboard surfacing appointment and patient activity
