QKTech Delivers Seamless CX and Device Performance for a Leading Private Bank
Industry & Segment
Banking & Financial Services
Objective
To demonstrate how QKTech enabled a large private bank to deliver resilient, high‑quality digital banking experiences at scale by strengthening customer experience, performance reliability, and device readiness across web and mobile platforms during a critical post‑merger transformation.
Client Overview
A large private bank embarked on a major digital transformation to modernize its mobile banking platform following a merger with a leading finance company. With over 80 million users relying on the digital retail banking channel, the bank aimed to modernize its digital platforms, deliver high‑quality, defect‑free experiences across web and mobile, and ensure resilient performance across diverse devices and environments.
To support this ambitious vision, QKTech was entrusted with spearheading customer experience (CX) and device performance engineering across critical touchpoints.
Business Challenges
Growth exposed three problems in how the contact center recorded and used its calls.
Massive user risk
Supporting over 80 million active users introduced significant risks to service continuity, data integrity, and customer trust in the event of performance issues.
High-stakes digital experience
With millions relying on mobile and web platforms daily, even minor glitches could lead to customer dissatisfaction and reputational damage.
Device & environment fragmentation
Delivering a consistent user experience across a fragmented device landscape posed a significant testing and validation challenge.
Limited visibility into live issues
The bank required real-time insights to catch experience-breaking issues before customers encountered them.
Need for round-the-clock reliability
Maintaining uninterrupted banking services across time zones demanded constant vigilance and instant response mechanisms.
Complex infrastructure landscape
Operating across a hybrid infrastructure of multi-cloud and on-premises systems added layers of coordination and complexity, heightening the risk of journey failures.
QKTech’s Approach & Solution
QKTech adopted a CX‑first, NFR‑led engineering approach to help the bank deliver reliable, high‑quality digital experiences at scale, even in the complexity of a post‑merger environment.
CX‑first engineering strategy
- We began by mapping critical mobile and web banking journeys and identifying high‑risk, high‑impact touchpoints. This ensured testing and monitoring efforts were aligned directly with customer experience and business outcomes
Embedded validation across agile delivery
- CX, performance, and device validation were embedded into agile sprints, enabling early detection of experience‑breaking issues and continuous feedback throughout the development lifecycle.
Proactive observability & monitoring
- QKTech implemented journey‑level synthetic monitoring, real‑time alerts, and business‑aligned dashboards to proactively detect issues before they reached customers, ensuring uninterrupted banking services.
Device & environment coverage at scale
- Digital journeys were validated across 50+ device and network combinations using a hybrid cloud and physical device lab, ensuring consistent experiences across fragmented environments.
Resilient, scalable execution
- The approach combined continuous monitoring, automated validation, and iterative optimization, allowing the bank to scale new digital offerings rapidly without compromising stability or performance.
