Custom software built with integrity and precision
PerformaCode provides custom software development services for complex production systems. Our teams work across embedded devices, backend platforms, web and mobile interfaces, and AI-enabled components that operate as part of larger software and hardware environments.
Most of our engagements take place inside existing products rather than greenfield projects. Clients typically bring us in when software systems have grown over time and require careful refactoring, integration, or expansion without disrupting ongoing operations. These environments often include inherited codebases, evolving product specifications, multiple hardware revisions, strict uptime requirements, and integration constraints across distributed platforms.
Our engineering work spans firmware and device software, backend and cloud architecture, API design, frontend and mobile development, as well as applied AI and computer vision integrated into production systems. Typical contributions include stabilizing complex codebases, system refactoring, performance optimization, cross-platform integration, interface development, and long-term maintenance of business-critical software.
PerformaCode supports organizations building and operating technology products across industries such as medical devices, consumer electronics, semiconductor equipment, industrial systems, logistics platforms, and connected devices. Our engineers contribute across multi-year product lifecycles, helping teams evolve existing systems while maintaining reliability and operational continuity.
Delivery is distributed between Costa Rica and Lithuania, supporting clients across North America and Europe.
PerformaCode Inc. offers competitive pricing that fits client budgets while delivering high value. Clients appreciate their proactive problem-solving and adaptability to changing needs, ensuring successful project outcomes without negative impacts on timelines.
