App Support and Software Maintenance for Fintech and Financial Services

Ongoing bug fixes, operating system and security patches, performance optimization, and feature development for your live application. The scope depends on your retainer. Most fintech teams want regular updates (weekly or bi-weekly), monitoring for breaking changes in dependencies, and a clear process for security patches. We work with your CTO to define SLAs and what 'urgent' means in your context.

Every security patch goes through a compliance checklist before release. We verify that audit trails remain intact, that transaction logging isn't disrupted, and that any encryption or data-handling changes still meet your regulatory requirements. This is built into our maintenance process, not a separate step. For fintech, this is non-negotiable.

Legacy application support is part of our core offering. Older fintech platforms often carry technical debt and outdated libraries, making them harder to maintain safely. We can stabilize them, migrate dependencies incrementally, and plan a path toward modernization. The key is understanding your constraints (whether it's API contracts, regulatory freezes, or business-critical functionality) and working within them.

Both happen within your retainer. We allocate team capacity based on your priorities and calendar. If you need a major feature, we pace it so maintenance (security patches, bug fixes, OS updates) doesn't slip. This requires clear communication with your product owner about what matters most in each cycle. We work as an extension of your team, not as a separate vendor.

Your retainer covers an on-call arrangement. We define what qualifies as an emergency (security vulnerability, transaction processing failure, data loss risk) and agree on response times upfront. Our UK, Spain, and Ukraine footprint means we can cover time zones where your users are active. Most fintech teams define a critical incident SLA of 2-4 hours for diagnosis and a plan.

Both. We set up monitoring for crashes, performance degradation, and transaction failures, so we catch issues before your users do. That feeds into manual review by developers who understand your domain. For fintech, alerting can't be automated alone because context matters (is a spike in database queries a real problem or expected batch activity?). Automated monitoring gives us speed; human judgment keeps us compliant.
