Hire the Best Reverse Engineers
in Ukraine

Hi — I reverse engineer protected systems and build the backend services that turn hard-to-get data into reliable products. What I do - API reverse engineering & web scraping — extract data from protected systems, bypass anti-bot measures (Akamai, Cloudflare, etc.), and turn it into stable, production-grade APIs. - Backend engineering — high-performance services in Go & Python, robust REST APIs, data pipelines, caching and scaling. - Automation & tooling — browser automation (Playwright), custom tooling for extraction/processing, integrations and orchestration. - Bots & integrations — Telegram bots and other integrations that connect complex workflows to usable interfaces. Why I’m different I don’t just “write a script.” I reverse-engineer how a system works, design a reliable solution, and deliver a maintainable service that your product can depend on. If it looks impossible — that’s when I get to work. If you need Protected data exposed as a stable API, A backend that scales and recovers from edge cases, or A custom integration that others can’t implement — I’m the one to call. Let’s build something that actually works 🚀

Mostly interested in reverse-engineering tasks of Windows applications. Have experience in programming: Assembler language, Delphi, C++, C#. Data extraction, parsing proprietary file formats. Dll injection, modify memory of the application.

I help clients solve difficult reverse engineering problems involving Windows software, Android apps, firmware, proprietary protocols, and protected binaries. C, C++, C#, Delphi, Visual Basic. My work focuses on targets that are undocumented, obfuscated, protected, or otherwise difficult to analyze without deep low-level experience. This includes application and APK reverse engineering, native library analysis, driver and firmware research, protocol reconstruction, key and decryption-flow analysis, unpacking, data extraction, and architecture-specific analysis across x86, x64, ARM, and PowerPC. I use IDA, Ghidra, Binary Ninja, Frida, debuggers, and traffic analysis tools where appropriate, but the real value is the ability to reduce uncertainty quickly, isolate the logic that matters, and deliver clear technical findings clients can act on. Typical engagements include recovering undocumented communication behavior, identifying validation or decryption logic, understanding protected binary behavior, and assessing the feasibility and risk of deeper analysis before larger commitments are made. I focus on precision, discretion, clear communication, and practical results.

Good mechanical design doesn't end with a finished CAD model. It starts with how the part will actually be made. I design production-ready parts, assemblies and technical drawings with DFM, CNC machining, tolerances and real-world manufacturing in mind. Feel free to contact me. ABOUT ME: I’m a Mechanical Design Engineer with over 16 years of hands-on experience in mechanical design, CNC machining, and manufacturing. I create production-ready parts, assemblies, mechanisms, and technical drawings for real-world manufacturing. I hold a mechanical engineering degree and operate a family-run CNC workshop in Kyiv, Ukraine, where I design, prototype, machine, assemble, and validate functional mechanical parts and assemblies. This practical manufacturing experience helps me make engineering decisions based not only on CAD geometry, but also on tooling access, tolerances, assembly requirements, material selection, production costs, and long-term reliability. My background combines Mechanical Design, Design for Manufacturing (DFM), CNC programming, reverse engineering, prototyping, technical documentation, GD&T, fits and tolerances, and production optimization. I work primarily in Fusion 360 for both design and manufacturing workflows. I understand the full product development cycle: engineering design, prototyping, testing, BOM creation, technical documentation, manufacturing planning, and cost-effective production. I design and build real, functional products — and apply that mindset to every engineering challenge. Whether you need a single manufacturing drawing, a production-ready CAD model, a mechanical assembly, a manufacturable redesign, or ongoing engineering support, I focus on delivering practical, reliable, and manufacturing-ready solutions. I value long-term collaborations, but I’m also available for focused standalone tasks such as mechanical design, production drawings, reverse engineering, and manufacturing documentation. WHAT I OFFER: I specialize in manufacturing-ready mechanical design, functional assemblies, production drawings, and engineering support, including: ✅ Mechanical Design of parts, assemblies, and mechanisms. ✅ Production-ready CAD models and technical drawings for CNC machining, fabrication, and manufacturing. ✅ Design for Manufacturing (DFM) to improve manufacturability, reduce production costs, and simplify assembly. ✅ GD&T, fits, tolerances, and engineering documentation for reliable production and assembly. ✅ Reverse Engineering of existing parts, products, and assemblies. ✅ Manufacturing support, CNC-oriented design, tooling, fixturing, and production optimization. ✅ Prototyping and product development support from concept through production. ✅ Long-term engineering collaboration for manufacturers, startups, and product development teams. Final Deliverables May Include: ● Production-ready 3D CAD models (Fusion 360 source files, .f3d, .f3z, .STEP, .IGES, .STL, .OBJ, and other required formats). ● Manufacturing drawings, production drawings, assembly drawings, fabrication drawings, and technical documentation prepared for CNC machining, fabrication, assembly, and production. ● Engineering drawings with GD&T, fits and tolerances, surface finish requirements, technical notes, section views, exploded views, and detailed manufacturing annotations. ● Bills of Materials (BOMs), assembly documentation, manufacturing documentation, production documentation, and sourcing-ready deliverables. ● CAM-ready geometry, Fusion 360 CAM files, CNC milling toolpaths, and manufacturing-ready solid models or surface geometry. ● Deliverables prepared for prototyping, supplier communication, manufacturing, inspection, assembly, and production workflows. Tools & Capabilities Fusion 360 CAD / CAM (licensed) CNC milling center (x1) In-house prototyping capabilities Precision measuring instruments My Work Ethic I take responsibility for deadlines, communication, and the outcome I value long-term collaboration over one-time gigs I communicate clearly about feasibility and don’t overpromise I provide clear technical reasoning, not just opinions I start working promptly and keep clients informed I aim to build lasting relationships with professionals who value quality Most of my work is protected under NDAs, so my public portfolio is limited. If you'd like to know more or see relevant examples, feel free to contact me — I’m always open to collaboration.

I`m a mechanical and industrial design engineer with more than 10 years experience in mechanical design, CAD/CAM and product skilled in SolidWorks and Fusion360 (part, assembly, complex surface, sheetmetal design, reverse engineering, engineering drawings and high quality renders).
