👋 Hi, I’m Matt - a senior C/C++ developer and reverse engineer with 15+ years of experience working across Windows internals, low-level systems, and complex software analysis.
My core expertise is understanding how software works under the hood. I specialise in reverse engineering applications, analysing Windows internals, debugging complex behaviour, and modifying or extending software at both user-mode and kernel level.
Over the years I’ve developed more than 500 desktop applications in C# and C++, built large-scale production systems used by millions of users, and led development teams delivering reliable, robust software for enterprise and financial organisations.
I operate comfortably at every layer of the stack - from kernel-mode drivers and memory analysis through to desktop applications, systems development, and backend platforms.
🔒 Windows Systems, C/C++ & Reverse Engineering
- Reverse engineering complex applications and software systems
- Understanding internal logic and reconstructing application behaviour
- Adding or modifying functionality in existing software
- Windows kernel driver development (WDM / KMDF)
- Static and dynamic analysis (IDA, Ghidra, x64dbg)
- Encryption / decryption analysis and algorithm reconstruction
- Anti-tampering and protection bypass analysis
- Driver debugging, crash dump analysis, BSOD investigation
- Syscalls, Windows exceptions, hooks and internal APIs
- Virtual / physical memory inspection and manipulation
- Assembly, pseudocode and binary analysis
- Researching undocumented Windows behaviour
- Performance optimisation at system level
If it runs on Windows, I can reverse engineer its logic, understand how it processes data, extract or reconstruct functionality, debug system-level issues, and alter behaviour where required - from user-mode applications down to kernel drivers.
🎮 Game Reverse Engineering, Cheats & Anti-Cheat Research
I have extensive experience reverse engineering games and building internal and external cheats, mods, and tooling.
- Internal and external game cheat development
- Reverse engineering game engines and client logic
- Working with major anti-cheat systems and protections
- Bypassing anti-tamper and protection mechanisms
- Game modding and functionality extensions
- Memory inspection, injection and runtime analysis
This experience requires deep understanding of low-level systems, memory, and complex software protections.
⚙️ Systems Development, Emulation & Embedded Work
Alongside Windows systems work, I also work with lower-level system development and emulation.
- Systems-level C/C++ development
- Emulator and virtualised environment development
- Hardware and device communication
- Embedded systems development
- DSP and signal processing related software
- Performance-critical low-level systems
🖥 High-Performance Desktop Applications
- High-performance Windows applications in C# and C++
- Real-time data processing systems
- Custom internal tooling and automation platforms
- Enterprise-grade desktop software supporting large user bases
Having built hundreds of desktop systems and applications - from simple console tools to enterprise-grade platforms supporting millions of users - I understand performance, optimisation, maintainability, and long-term stability.
🏗 Backend Systems & Platform Architecture
- Scalable backend systems and APIs
- Client/server architecture and communication pipelines
- Authentication, licensing and secure system design
- Database architecture and performance optimisation
- Refactoring and stabilising legacy systems
I design systems for long-term stability and scale - not fragile MVPs.
👥 Technical Leadership & End-to-End Ownership
- Led and managed teams of 3–20 engineers
- Architecture ownership from concept to release
- Code reviews, mentoring and engineering standards
- Direct stakeholder and founder collaboration
- Delivery planning and execution
I don’t just write code - I take ownership of the outcome. Having worked with major financial institutions and enterprise organisations, I understand what works at scale, how to communicate complex technical decisions clearly, and how to deliver reliable, production-ready systems that stand up to scrutiny.
💡 Commercial & Technical Experience Combined
I bring both deep low-level technical expertise and real commercial product experience. I’ve built profitable software businesses, worked with enterprise organisations, and understand the balance between engineering excellence and practical delivery.
🤝 Let’s Connect
If you need help reverse engineering an application, analysing complex Windows behaviour, developing C/C++ systems, debugging difficult problems, or extending existing software - I would love to hear from you.
I’m always happy to chat through ideas, provide honest technical advice, or take ownership of a project and see it through properly.
Hopefully speak soon.

Most AI automations look great in a demo and quietly break in production. I build the ones that actually run your business, deployed in about a week and hardened from day one.
I'm an AI automation engineer who turns slow, manual business processes into reliable systems that pay for themselves fast. Using Claude Code, MCP, and modern AI tooling, I ship working automations in days, not quarters, then lock them down so they survive real traffic, security reviews, and 2 AM edge cases.
What I automate (and the payback that follows):
Lead-to-cash workflows: intake, qualification, CRM sync, and follow-up that recover hours every week and stop deals slipping through the cracks.
Document and data pipelines: contracts, invoices, reports, and records parsed, routed, and filed automatically with full audit trails.
Internal ops and back-office: onboarding, ticket triage, reporting, and approvals wired together across the tools you already use.
Custom AI agents: Claude-powered assistants and MCP integrations connected to your real systems, not a sandbox.
How I work:
1. Scope call: we pin down the one process costing you the most time or money.
2. Build sprint (days, not months): I ship a working automation fast, with you reviewing progress along the way.
3. Harden and hand off: secrets management, least-privilege access, encryption, and a written runbook so it keeps running after I'm gone.
4. Live in about a week: most projects deliver measurable payback within the first week or two of going live.
Why clients hire me over a cheaper option: speed and security usually come as a trade-off. I deliver both. Every build ships with non-root containers, isolated environments, secrets rotation (Vault or AWS Secrets Manager), and SOC 2, HIPAA, and GDPR-aligned practices baked in, so what works in week one still passes an audit in month six.
Stacks: Claude Code, MCP, OpenAI, Gemini. AWS, GCP, Azure, DigitalOcean, on-prem. Docker, Tailscale, Cloudflare Tunnel, WireGuard.
Best fit for: founders and ops or engineering leaders in legal, finance, healthcare, and compliance-bound SaaS who need automation that's fast to ship and safe to trust.
A quick first step: message me the one process eating the most time in your week. I'll send back a short, no-obligation plan for automating it, usually within a couple of hours during business hours.

$700K+ delivered on Upwork across 145 projects with a 100% Job Success Score. I architect and ship production AI systems, Voice AI agents handling live calls under 2-second latency, computer vision platforms processing 8M+ daily events, and full-stack products running in production for years.
What I build:
𝗩𝗼𝗶𝗰𝗲 𝗔𝗜 & 𝗖𝗼𝗻𝘃𝗲𝗿𝘀𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗔𝗴𝗲𝗻𝘁𝘀 Real-time voice pipelines combining speech-to-text, LLM reasoning, and natural voice synthesis. I built SloanConnect, an AI telephony platform that automates insurance verification calls end-to-end, navigates IVR systems, holds dynamic conversations with representatives, and scales to hundreds of concurrent calls. Sub-2-second response time, encrypted compliance handling, production-stable.
𝗖𝗼𝗺𝗽𝘂𝘁𝗲𝗿 𝗩𝗶𝘀𝗶𝗼𝗻 𝗮𝘁 𝗦𝗰𝗮𝗹𝗲 Lead AI Engineer on two production CV platforms: Adlytic - privacy-safe in-store retail analytics with GDPR-compliant pipelines, heatmaps, and POS integration, and SportsEye - real-time soccer analytics from broadcast feeds with 96% accuracy across player tracking, field mapping, and tactical metrics with zero on-field hardware.
𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 Hybrid recommendation engines on PySpark processing 8M+ daily impressions. NLP and sentiment systems wired into live dashboards. Healthcare process automation with HIPAA-aligned data handling. Models built to live in real environments, not notebooks.
𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗟𝗟𝗠 𝗪𝗼𝗿𝗸𝗳𝗹𝗼𝘄𝘀 (𝗖𝗹𝗮𝘂𝗱𝗲, 𝗢𝗽𝗲𝗻𝗔𝗜, 𝗺𝘂𝗹𝘁𝗶-𝗺𝗼𝗱𝗲𝗹) End-to-end AI agents shipped to production: a Shopify + Amazon SP-API customer service agent with order lookup, refunds, returnless-refund policies, Slack/Email approval gates, and Klaviyo sync. Multi-step LLM pipelines with tool use, RAG, function calling, and human-in-the-loop checkpoints. I design these as systems, not single prompts, and I'm comfortable across Claude, OpenAI, and open-weight models depending on what fits the workload.
𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻𝘀 Every AI product needs scaffolding that holds. I've shipped Django/Node/React/Next.js platforms that ran 3+ years in production, Alchemist Real Estate, audIT.app, and a long-running B2B SaaS that grew from MVP to hundreds of users across $195K+ in contracted development. Distributed backends, REST/GraphQL APIs, AWS-native deployment, data pipelines, and the DevOps to keep them stable.
𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 As Lead Engineering Architect, I stay hands-on through the whole lifecycle, discovery, architecture, core implementation, deployment, and the long tail. I don't hand off and disappear. Most of my Upwork work is repeat business or long contracts measured in years, not weeks.
If you're building a Voice AI agent, a computer vision platform, an LLM-driven workflow, or a full-stack AI product that needs to survive real load - let's talk.
