We specialize in transforming legacy systems into secure, scalable, and high-performing solutions that reduce interruptions to your daily operations.
About Us
For SysGears, modernization means much more than just engineering, it’s about unblocking innovation. We offer end-to-end software modernization, including cloud migration, architecture redesign, security improvements, UI/UX upgrades, and performance tuning. Trusted by companies across fintech, logistics, healthcare, and e-commerce, we’ve been helping businesses achieve better outcomes and stay competitive in a changing digital landscape.
How We Are Different
We bring over 15 years of experience in delivering reliable software solutions.
End-to-End Application Modernization Services
SysGears starts the modernization process with an in-depth audit of your existing software and infrastructure. We uncover workflow inefficiencies, system security and performance issues, and hidden costs that stifle business growth. Our experts translate these findings into a clear roadmap with priorities, cost estimates, and modernization strategies customized to your goals, making sure you gain full clarity before investing in upgrades.
We design cloud migration strategies that fit your business model and technical environment. Whether migrating from on-premise or optimizing an existing cloud environment, we ensure minimal downtime, data integrity, and effective resource utilization. Modern cloud deployment strategies make your solution faster, more efficient, and secure, while significantly simplifying future updates and day-to-day maintenance.
Application Re-Architecting & Re-Engineering
Our team re-architects and re-engineers legacy systems that can’t meet modern demands due to age, design inefficiencies, or updated company goals. We rebuild outdated apps to improve availability, elasticity, and performance, and to help scale and simplify your software development process. Our engineers provide an extensive range of services from implementing serverless computing and infrastructure as code to designing, developing, and deploying data processing pipelines and microservice-based solutions.
Code Refactoring & Version Updates
Not every application requires a complete rebuild. Often, the challenge lies in inefficient code structures, outdated frameworks, or legacy dependencies. At SysGears, we modernize your application through code refactoring and tech stack upgrades, using the latest frameworks and tools. This improves performance, reduces bugs, and makes software easier to extend and maintain in the future. With an optimized codebase, your team spends less time on fixing legacy issues and more time on innovation.
SysGears transforms legacy interfaces into modern, user-friendly experiences with the help of clean design, consistent navigation, and business-oriented user flows. By applying general and domain-specific best practices, we turn complex workflows into simple, productive, and engaging journeys for users. With a modernized UI/UX, your software becomes not just functional but enjoyable to use, leading to stronger brand loyalty and higher adoption rates.
Mobile & Cross-Platform Enablement
Our engineers can migrate your outdated mobile apps to a cross-platform technology stack, simplifying your software ecosystem, saving development costs on future upgrades and maintenance, and ensuring a consistent user experience across iOS and Android platforms. Whether on tablet or phone, iOS or Android, we ensure your solution is reliable, responsive, and optimized for every screen, providing your users with a high-quality product.
At SysGears, we integrate legacy systems with modern third-party services and solutions to enable seamless data exchange across all your business processes, enhance day-to-day productivity, or facilitate the gradual adoption of new software. Our team also designs and develops custom APIs that enable seamless B2B integration with your software for partners or clients, or help transform your existing software into a SaaS solution.
We migrate data storage and processing to modern platforms, optimized for speed, security, and usability.

FAQ
How do you determine if your application needs modernization?
The signs that your application needs modernization show in everyday operations: slow load times, rising maintenance costs, frequent downtime, frustrated users, or difficulty scaling to meet new business demands. Outdated UI/UX, poor security compliance, and a lack of integration with modern systems are other strong indicators that it’s time for an upgrade. At SysGears, we start with a comprehensive software audit to pinpoint bottlenecks and create a clear modernization roadmap.
Why should you consider SysGears as an application modernization provider?
With over 15 years of experience, a proven track record, and 350 successful projects, SysGears brings technical expertise and business insight to every stage of the modernization process. We’ve been modernizing applications across industries – from finance to logistics. We customize our modernization strategy to your specific goals, whether that’s reducing costs, enhancing security, upgrading your technology stack for higher development efficiency and maintainability, futureproofing, or introducing new integrations to your existing system.
How long does it take to upgrade an application?
The duration depends on the complexity of your application, its current architecture, and the scope of modernization. Small updates, like UI improvements or code refactoring, can take a few weeks, while full-scale re-architecting can span several months. At SysGears, we ensure every milestone is met without unnecessary delays or interruptions to your operations. However, our goal is not just speed, but delivering sustainable improvements that stand the test of time.
Can legacy applications be modernized with zero operational downtime?
Even though downtime is not an option for most businesses, zero-downtime modernization is not 100% achievable. Yet, keeping that aspirational goal in mind, SysGears applies phased migration strategies, containerization, and parallel environments to minimize disruption risks and safeguard business continuity during legacy system upgrades. This way, your team can continue working with minimal interruptions, while your users experience minimal downtime.
Is it feasible to modernize a legacy app when functional specifications are missing?
Yes, even without detailed documentation, SysGears can modernize legacy systems by applying reverse engineering, conducting audits, and collaborating closely with your team. As a result, you get not just a modernized system that matches business requirements and performs reliably, but also clear, up-to-date documentation that makes future updates easier and faster.
