Cover image for A self-service portal that lets
A self-service portal that lets a freight forwarder's customers prepare their own shipping documents online, instead of emailing drafts back and forth. The old process: a customer emails their shipping instructions, the forwarder's documentation team keys them into a draft Bill of Lading, emails a PDF back, the customer spots a typo, and the loop repeats. Every round trip is a chance to get a consignee address wrong. Now the customer logs in and drafts it themselves. They fill the House Bill of Lading or Air Waybill form directly — shipper, consignee, routing, flights, charges — save it as a draft, edit it as many times as they need, copy a previous shipment for a repeat booking, and print a draft PDF to check. When they submit, the record locks, becomes read-only, and a generated PDF goes to the documentation team. Multi-tenant, so each customer sees only their own documents. Built with C# / ASP.NET (http://ASP.NET) and SQL Server.

Cover image for A web platform that replaced
A web platform that replaced a paper-and-email credit approval process with a tracked digital workflow. Before it, a customer's credit request moved through the company as a form that got signed, scanned, emailed and chased. Nobody could answer "where is it right now?" without phoning three people. The system turns that into a seven-level sequential approval chain — sales person raises the request with the limit, terms, financials and supporting documents; it moves through sales head, branch accounts, branch head, head office, SBU head and finally corporate approval. Each level sees exactly what it needs, every action is timestamped and attributed, and stakeholders are notified by email as it moves. On final approval the credit facility goes live automatically. It also generates the PDF reports management uses to review exposure across branches. Built with C# / ASP.NET (http://ASP.NET) and SQL Server.

Cover image for A messaging API that lets
A messaging API that lets businesses send WhatsApp messages and documents from their own number, programmatically. The problem it solves: a small business wants to send order confirmations, receipts and invoices on WhatsApp — where their customers actually are — but the enterprise options are heavy, slow to get approved, and priced for companies far larger than them. So I built the alternative. One REST endpoint to send a message, another to attach a PDF, and delivery webhooks so your system knows what landed. OTP codes with expiry and attempt limits for login and 2FA. SDK examples in seven languages, a dashboard to manage it, and a subscription that starts at $19/month. I designed, built and shipped the whole thing — API, dashboard, billing, docs and marketing site. Node.js and TypeScript on the backend, Astro for the site.

Cover image for LogiSoft is a freight-forwarding ERP
LogiSoft is a freight-forwarding ERP I designed and built for logistics companies that were running their operations on spreadsheets and email. It covers the full shipment lifecycle in one system: customer and carrier bookings, sea and air import/export jobs, house and master bills of lading, allotments, invoicing, and finance — with party master data and role-based administration underneath. The part I'm most proud of is the document handling. Instead of staff re-keying details from incoming shipping documents, the system reads them and maps the data straight into the right ERP fields. I built that on the Claude API, along with an in-app assistant that answers questions about shipments and lets users ask for what they need in plain language. Built with C#/.NET and SQL Server, with a web front end. It's in daily production use. What I do best: taking a messy, paper-heavy business process and turning it into software people actually want to use.

Cover image for Grim Lens is a local-first
Grim Lens is a local-first malware intelligence and threat-hunting workbench I built for security teams that need to analyze evidence without sending sensitive samples to the cloud. The platform ingests static artifacts such as PE metadata, strings, YARA matches, decoded configurations, PCAP summaries, and screenshots, then organizes them into investigation cases with risk scoring, enrichment, reporting, and cross-case intelligence. I designed the system around a strict security boundary: no sample execution, no automatic uploads, and no outbound enrichment unless explicitly requested. The backend is built in Rust using Axum, Tokio, SQLx, SQLite, YARA-X, and structured analysis modules, while the desktop interface is built with Avalonia/.NET 10 using MVVM and interactive charts. Key engineering work included: Local-first malware case management Static PE analysis and entropy inspection YARA rule matching and rule-pack management Threat-intelligence enrichment using services such as VirusTotal, abuse.ch (http://abuse.ch), and AlienVault OTX Rate limiting and TTL caching for external enrichment Cross-case indicator correlation Automated Markdown and PDF report generation Risk distribution, family, and category dashboards Rust REST API with structured validation and errors SQLite-backed local storage and migrations Cross-platform Avalonia desktop application CI builds and packaged Windows/Linux releases The result is a practical analyst workbench that turns scattered malware artifacts into a structured, searchable casebook while keeping control of sensitive data on the analyst’s own workstation.

Cover image for Most companies don't need another
Most companies don't need another 80-page security report. They need someone to tell them: What can actually be exploited? What could it cost us? And what should we fix first? That's the difference between checking a cybersecurity box and actually improving your security. When I assess an application or infrastructure, I'm not interested in filling a report with 50 low-impact findings just to make it look impressive. I care about attack paths. → Can authentication be bypassed? → Can one compromised account lead to something bigger? → Are APIs exposing data they shouldn't? → Can permissions be chained into privilege escalation? → Are cloud or infrastructure misconfigurations creating an easy entry point? → Would your monitoring actually notice an attacker? And most importantly: What should your team fix first? That's the approach I bring to cybersecurity work — whether it's penetration testing, security audits, SOC/security monitoring, or security consulting. I'm currently taking on new projects through Contra. If you're building a SaaS product, web application, API, or growing infrastructure and you're unsure how it would hold up against a real attack, send me a message. I'll happily take a look at what you're building and tell you where I'd start.

Cover image for ShadowForge is an adversary-emulation and
ShadowForge is an adversary-emulation and security-validation platform I built to help security teams model attack scenarios, visualize activity, correlate threat intelligence, and evaluate defensive visibility from a single operations interface. The platform brings together scenario orchestration, network visualization, threat intelligence, MITRE ATT&CK mapping, enterprise identity simulation, analytics, and reporting into one unified workflow. I designed the application around modular simulation components so authorized lab and security-validation exercises can be configured, observed, and translated into useful defensive findings rather than scattered logs and manual notes. Key engineering work included: Centralized security operations dashboard Configurable adversary-emulation scenarios Reconnaissance and environment-discovery simulation Lateral-movement and persistence scenario modeling Live execution-event visualization Network topology and host mapping MITRE ATT&CK technique mapping Threat-intelligence and IOC enrichment Enterprise user simulation for realistic lab scenarios Security analytics and severity tracking Automated findings and report generation Modular architecture designed for controlled security testing ShadowForge turns an authorized security exercise into something measurable: operators can configure a scenario, observe activity as it happens, correlate findings with threat intelligence and ATT&CK techniques, and produce structured results for defensive analysis. Built for controlled labs, security validation, and authorized adversary-emulation environments.
