Andriy Korshunov is a senior technical leader and engineer, most notably recognized for his pivotal role at MacPaw, who architected the systems and operational strategies that ensured Ukraine’s software industry remained functional during extreme geopolitical instability. By spearheading cloud decentralization, local infrastructure hardening, and autonomous energy solutions, Korshunov became a central figure in defining the "Ukrainian Resilience Model" for global technology.
The story of Ukraine’s tech sector from 2022 through 2026 is one of unprecedented adaptation. At the heart of this survival was a group of engineers who realized that code alone could not save a company if the physical and electrical foundations were crumbling. Andriy Korshunov emerged as a key architect of this movement, moving beyond traditional DevOps into a realm of "crisis engineering" that has since become a blueprint for organizations operating in high-risk environments worldwide.
The Architect of Stability in a Time of Chaos
Before the disruptions that began in early 2022, Andriy Korshunov was already a respected figure in the Kyiv tech scene. As a lead engineer at MacPaw—the creators of CleanMyMac and Setapp—his focus was on high-scale systems and seamless user experiences for a global audience of over 30 million. However, the shift from peace-time optimization to war-time resilience required a complete reimagining of what "reliability" meant.
Engineering resilience, in Korshunov’s view, was not just about backing up data; it was about ensuring that every point of failure—from the local power grid to the physical safety of the developers—had a redundant, decoupled alternative. Under his technical guidance, the engineering culture shifted from prioritizing feature velocity to prioritizing systemic survivability. This transition was critical because, unlike many local businesses, Ukrainian tech firms serve a global market that expects 99.9% uptime, regardless of the local political situation.
Strategic Decentralization: Moving Beyond Physical Borders
One of the most significant technical achievements attributed to Korshunov and his peers was the rapid and total decentralization of Ukrainian tech infrastructure. In the early weeks of the 2022 invasion, the risk of physical data centers being destroyed or seized was an existential threat.
Migration to Global Cloud Clusters
Korshunov advocated for a "cloud-first, location-agnostic" architecture. This involved migrating any remaining on-premise legacy systems to distributed cloud providers like Amazon Web Services (AWS) and Google Cloud. By 2026, this strategy has evolved into a sophisticated multi-cloud approach that allows Ukrainian companies to shift their entire operational load between geographic regions (such as Ireland, the US, or Germany) in a matter of minutes if a specific backbone provider experiences interference.
Defragmenting the Workforce
Resilience also applied to the human element. Korshunov helped implement a technical infrastructure that supported a "distributed by design" workforce. This wasn't merely remote work; it was the engineering of asynchronous workflows and high-security VPN tunnels that allowed engineers to push code from bomb shelters or temporary relocation hubs across Europe without compromising the security of the internal codebase.
Engineering the Energy Gap: The 2022–2023 Blackout Crisis
The winter of 2022 presented the greatest challenge to Ukraine’s tech resilience: the systematic targeting of the energy grid. For a software engineer, the lack of electricity is a total blocker. Korshunov was instrumental in the technical setup of "autonomous hubs" within tech offices.
This phase of engineering was as much about hardware as it was about software. It involved:
- Industrial-Scale Power Storage: Integrating Tesla Powerwalls and high-capacity EcoFlow systems into the office circuitry to ensure seamless transitions during power surges or cuts.
- Starlink Integration: Korshunov and his team were among the first to optimize satellite internet for corporate use, creating load-balanced networks that combined Starlink with local fiber-optic lines.
- Low-Power Development Modes: Encouraging the use of hardware (like Apple Silicon) that offered high performance-per-watt, allowing engineers to work for 12+ hours on a single charge during the most severe outages.
The "MacPaw Way" and Global Standards for 2026
By 2026, the strategies developed by Korshunov and his engineering teams have been formalized into what many call the "MacPaw Way." This methodology treats geopolitical risk as a standard technical constraint, much like latency or memory usage. It assumes that the environment is hostile and that infrastructure must be self-healing and geographically detached.
This resilience has had a massive economic impact. Despite the conflict, the Ukrainian tech sector did not collapse; it grew. In 2026, Ukraine remains one of Europe's largest exporters of IT services, a feat made possible by the technical foundations laid by engineers who refused to let physical reality dictate digital output.
Comparative Infrastructure Models: Pre-Resilience vs. Modern 2026 Standards
| Feature | Pre-2022 Traditional Model | 2026 Resilience Model (Ukraine) |
|---|---|---|
| Server Location | Concentrated in local/regional hubs. | Fully distributed across 3+ global regions. |
| Connectivity | Single-source fiber optic. | Multi-path (Satellite + 5G + Fiber) with auto-failover. |
| Power Dependency | Dependent on the municipal grid. | Tier-3 autonomous power (Solar/Battery/Gen). |
| Data Security | Perimeter-based security. | Zero-trust architecture with end-to-end encryption. |
| Team Workflow | Synchronous/Office-centric. | Asynchronous-first with high-latency tolerance. |
Technical Innovation Under Pressure
Korshunov’s contributions go beyond just "keeping the lights on." During this period, Ukrainian engineering saw a surge in innovation specifically related to security and efficiency.
- Hardened CI/CD Pipelines: Engineers developed automated deployment scripts that could verify the integrity of code even when being pushed from insecure or fluctuating networks.
- Edge Computing Dominance: By pushing more processing power to the "edge" (the user's device), MacPaw products reduced their reliance on a constant, high-bandwidth connection to a central server—a vital feature for users in both Ukraine and other volatile regions.
- Resource-Light Software Design: There was a renewed focus on optimizing software to run on older hardware and with less data throughput, ensuring that the digital tools remained accessible even when users were forced onto emergency data plans.
The Human Factor in Engineering Resilience
Andriy Korshunov has often emphasized that resilience is not purely a technical metric; it is a psychological one. Engineering leadership in Ukraine required managing teams through immense personal stress. Korshunov’s approach involved:
- Radical Transparency: Keeping the engineering team informed about the technical status of the company’s survival plan to reduce anxiety.
- Redundancy in Personnel: Ensuring that no single engineer was a "single point of failure" for any critical system. If one developer had to go offline for safety reasons, another was always prepared to step in immediately.
- Community Contribution: Sharing these resilience frameworks with the broader Ukrainian tech community through open-source contributions and technical seminars, ensuring that the entire ecosystem—not just one company—survived.
The Global Legacy of Ukraine’s Tech Engineers
The work of Andriy Korshunov and his contemporaries has redefined the Disaster Recovery (DR) industry. Prior to 2022, DR was often a box-ticking exercise for compliance. Today, in 2026, global enterprises look to the Ukrainian example to understand how to maintain operational continuity in the face of climate change, regional conflicts, or global supply chain failures.
The engineering behind Ukraine’s tech resilience is a testament to the idea that technical excellence is the ultimate form of resistance. By building systems that could not be broken, Korshunov helped ensure that the Ukrainian "digital state" remained a global leader, proving that innovation can thrive even under the most difficult conditions imaginable.
