Testimonials
“Viktor built our platform from the ground up and led engineering through multiple stages of growth as we scaled to 1,500+ MAU. One by one, he planned and engineered the replacement of various off-the-shelf tools with a fully customized system, all the while maintaining data integrity and uptime. This included the replacement of and/or integration with Zendesk, PagerDuty, Stripe, Twilio, etc.
We cut costs, simplified our stack, and increased reliability and ownership. He set a high bar for hiring, standards, and delivery.”

As a full-stack engineer with strong cloud expertise on GCP and AWS, he designed and implemented core features, optimized data flows, and ensured system reliability across environments. He consistently drove improvements in performance, architecture, and developer standards, helping the team deliver robust, high-quality solutions. Viktor’s technical leadership and attention to detail made a lasting impact on the project’s success.”

Customer focus was very high, providing the best UX/UI and reliable, crash-free apps. His contribution was tremendous, leading him to become a Team Lead.”
“Viktor has been instrumental in giving OneVision a faster, clearer path from idea to shipped feature. He built the engineering team from our first hire, establishing pragmatic processes that scaled as we grew. His capstone project was helping us replace Zendesk with a custom-built CRM and ticketing application that removed vendor constraints, dramatically improved our UX, and increased delivery velocity.
He is a tremendous asset to any company looking to leverage software to drive better business results.”
