👋 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. Matt

Upwork is one of the best places in the world to find great developers — but that’s only half the equation. If you’ve hired offshore talent on Upwork, you already know the story: - You find amazing developers at great rates… and then things slow down. - One quick question takes a full day to answer because of time zones. - Features get built differently than what you envisioned. - And you end up managing chaos instead of progress. The problem isn’t the developers — it’s the missing system between your vision and their execution. That’s exactly what I fix. 🚀 Who I Am I’m Pete Jaworski, one of Upwork’s Top-Rated Product Managers and Scrum Masters, with 10+ years leading distributed teams across 12 time zones. I help founders and startups make offshore development actually work — with structure, visibility, and accountability built into every sprint. 🔧 What I Do I install the operating system your project needs to move fast — without you needing to micromanage: ✅ Translate ideas into developer-ready build plans ✅ Eliminate confusion through structured discovery and requirements ✅ Keep projects moving asynchronously (no more waiting overnight) ✅ Track blockers, sprint velocity, and code commits automatically ✅ Give you clear dashboards showing where your dev dollars go 🧠 My System Product leadership for offshore teams. It bridges every gap between you and your developers — so they stay focused on building while you stay focused on strategy. Results delivered: - 70% faster delivery - 50% less rework - 95% of milestones completed on time 🌍 Who I Help - Founders managing offshore teams on Upwork - Startups building MVPs with remote developers - Small dev agencies needing structure and Scrum oversight - Entrepreneurs tired of “busy projects” that never launch If you’ve already found great developers on Upwork, let’s make sure they actually deliver. I’ll bring the clarity, structure, and leadership that turns your offshore freelancers into a high-performing product team. ➜ 𝐌𝐲 𝐒𝐤𝐢𝐥𝐥𝐬 & 𝐄𝐱𝐩𝐞𝐫𝐭𝐢𝐬𝐞: 🔹Agile Product Manager 🔹AI Implementation Specialist 🔹AI Product Development Expert 🔹AI Product Manager 🔹AI Software Development Specialist 🔹AI Technology Specialist 🔹Certified Product Owner 🔹Chief Product Officer 🔹Cross-functional team Leadership 🔹CTO & Project Manager SaaS 🔹Experienced IT Project Manager 🔹Experienced Product Owner 🔹Experienced Software Project Manager 🔹Expert Growth Product Manager 🔹Expert Product Manager 🔹Expert Product Owner 🔹Expert Technical Leader 🔹Fractional CTO 🔹Full-stack development Specialist 🔹Jira Service Management 🔹Lean Startup 🔹Minimum Viable Product 🔹Operations Project Manager 🔹Product Discovery 🔹Product Launch Expert 🔹Product Management Specialist 🔹Product Roadmap 🔹Project Implementation Specialist 🔹Project Management Consultant Expert 🔹Roadmap Planning 🔹SaaS Product Manager 🔹Scrum Master 🔹Senior Full Stack Developer 🔹Senior Project Manager 🔹Senior QA Engineer 🔹Software Architecture & Design 🔹Strategic Product Manager 🔹Technical Product Manager & Developer 🔹Technical Project Manager 🔹Technical Requirement Analysis 🔹Technical Software Development Manager 🔹Technical Support Specialist 🔹Web Development Specialist 🔹QA Testing Specialist . . . . . . . . . . . . . . . . . . . . . . . .
