Software projects don't fail because teams lack talent—they fail because of poor communication, unclear priorities, unmanaged risks, and missed deadlines. I help businesses deliver software successfully by bringing structure, technical leadership, and accountability throughout the entire project lifecycle. With 10+ years of experience across software development and technical project management, I bridge the gap between business and engineering—keeping stakeholders aligned, teams focused, and projects moving from discovery to successful delivery. Having worked on SaaS platforms, web applications, mobile apps, enterprise software, API integrations, cloud solutions, and AI-powered products, I understand the technical challenges behind software delivery while maintaining a strong focus on business outcomes. Whether you're launching a new product, scaling an existing platform, coordinating distributed engineering teams, or delivering AI-enabled solutions, I provide the leadership needed to keep projects on track and deliver results. 🚀 What I Can Help With Technical Project Management ✔ End-to-end software delivery ✔ Agile & Scrum project leadership ✔ Sprint planning & backlog management ✔ Roadmap planning & execution ✔ Risk, issue & dependency management ✔ Budget & timeline management ✔ Stakeholder communication ✔ Release planning & production readiness Software Delivery ✔ SaaS platforms ✔ Web & mobile applications ✔ MVP development ✔ Enterprise software ✔ Product launches ✔ SDLC management ✔ Cross-functional team leadership ✔ Distributed team coordination AI & Emerging Technologies ✔ AI-powered software delivery ✔ LLM integration projects ✔ AI workflow automation ✔ AI product coordination ✔ Engineering & product collaboration Technical Coordination ✔ API integrations ✔ Third-party platform integrations ✔ Cloud-based solutions ✔ Vendor management ✔ Technical discovery workshops ✔ Requirements gathering ✔ Process improvement & delivery optimisation 🛠 Tools Project Management Jira • Azure DevOps • ClickUp • Asana • Trello • Microsoft Project Documentation & Collaboration Confluence • Miro • Slack • Microsoft Teams Technical GitHub • REST APIs • SDLC • Agile • Scrum • Kanban 💡 Why Clients Work With Me ✔ Technical background that enables effective communication with developers and engineering teams. ✔ Proven experience leading software delivery across startups, agencies, and enterprise environments. ✔ Strong focus on execution, transparency, and measurable business outcomes. ✔ Ability to translate business requirements into actionable delivery plans. ✔ Comfortable managing remote, cross-functional teams across multiple time zones. ✔ Proactive risk management to keep projects moving and avoid costly delays. 🎯 My Approach I believe successful software delivery isn't about adding more meetings or unnecessary processes. It's about creating clarity, removing blockers early, keeping stakeholders informed, and helping engineering teams stay focused on building great products. I combine technical understanding with practical project leadership to ensure software is delivered efficiently, predictably, and with minimal friction. My goal is simple: Deliver quality software on time, keep teams aligned, and help clients achieve their business objectives.

During my 20+ years in software development I have been focusing on several areas: - Real time audio and network communication; - Audio processing algorithms for both speech and music; - Cross-platform c++ development including desktop, mobile and embedded systems; - Using Qt framework for both UX and core functionality. - Designing and supporting client-server systems for real time communication. - Linux setup and administration (especially in networking, audio and performance departments) for development, testing and production needs. - Scripting (mostly bash, python and octave) for automation and prototyping. - Data analysis and processing algorithms. You can find more detailed info about the projects I participated in the employment history and on my linked GitHub page. Even though I have been in the industry for quite a while, the thing I love the most about IT is learning new things and exploring new paths. I have strong problem solving skills and have always been looking for new challenges. This was one of the reasons why I decided to try freelance. I also have strong background in math and physics (my PhD thesis was about using quantum field theory math apparatus in the theory of turbulence). I have been consistently using this background throughout my career in IT for complex algorithm development, DSP and data analysis. I also did side projects about using computer vision and machine learning for music analysis and synthesis, although I wouldn't call myself a profi in these areas.

I build complete products end to end: frontend, backend, database and blockchain integration, usually as the only developer on them. For the last four years I have run most of the frontend and about half of the backend of a live real-money gaming platform (under NDA): slots, crash games, roulette, blackjack and poker, built with PixiJS, Spine, GSAP and TypeScript. One of those games went from an empty repository to a public launch in under two weeks. What I do: - Games: PixiJS, Spine, GSAP, TypeScript, Unity3D. Slots, crash, table games, and an NFT game with its own token. - Web: Vue.js, React, TypeScript, Node.js, PostgreSQL, MySQL. - On-chain payments: deposits and withdrawals across Solana, TON, Polygon, WAX, Ronin and BNB Chain; NFT transfers; a custom token; Telegram bots with Stars payments. - AI-assisted delivery: I write custom Claude skills to automate what generic tooling handles badly (for example Figma-to-code for React, Vue and PixiJS), and I set up local LLM workflows for clients who cannot send code to cloud models. - The expensive, boring part: race conditions, replay protection, rate limiting. If a player can fire a thousand concurrent requests at an endpoint, sooner or later somebody will. 20+ years of programming, starting with x86 assembly. I work through my own Polish company on B2B contracts, remote, with a comfortable overlap with US Eastern hours.
