Success Stories
See how we've transformed application support from a cost center into a value driver for our clients.
From Reactive Chaos to Proactive Stability
The Problem: The client's in-house team was overwhelmed with production issues, leading to frequent outages during peak processing times. Their reactive approach meant they were constantly firefighting, which stalled new feature development and eroded customer trust.
Key Challenges:
- Unpredictable performance spikes causing transaction failures.
- Lack of 24/7 monitoring leading to slow incident response times overnight.
- Growing technical debt making bug fixes complex and time-consuming.
- Inability to meet the 99.95% uptime SLA demanded by enterprise customers.
Our Solution:
- Implemented a 24/7 SRE pod to provide follow-the-sun monitoring and incident management.
- Deployed a comprehensive observability stack using Prometheus and Grafana to gain deep insights into application performance.
- Established clear error budgets and SLOs, shifting the focus from reactive fixing to proactive reliability engineering.
- Dedicated a Level 3 support team to systematically address technical debt and refactor problematic code modules.
Accelerating Innovation by Offloading Maintenance
The Problem: The client's senior developers were spending over 50% of their time on customer-reported bugs and minor feature requests. This support burden was derailing their product roadmap and slowing down innovation, allowing competitors to gain ground.
Key Challenges:
- High-value engineers were bogged down with low-impact support tasks.
- A growing backlog of small bugs and feature requests was frustrating customers.
- The onboarding process for new tenants was slow and manual.
- Inconsistent application performance across different tenants.
Our Solution:
- Established a dedicated L2/L3 support team to handle all incoming tickets, providing code-level fixes.
- Created a separate "enhancements" pod to manage and deploy the backlog of minor feature requests in bi-weekly sprints.
- Automated key parts of the tenant onboarding process, reducing manual effort and errors.
- Performed a deep performance audit and optimized database queries, resulting in consistent performance for all tenants.
Securing and Stabilizing a Mission-Critical Legacy Platform
The Problem: The client's core revenue-generating platform was built on an outdated technology stack. It was difficult to maintain, vulnerable to security threats, and couldn't handle traffic surges, leading to lost sales and significant business risk.
Key Challenges:
- Outdated dependencies with known security vulnerabilities (unpatched).
- Frequent crashes during high-traffic events like Black Friday.
- Lack of documentation and specialized knowledge to manage the system.
- High cloud hosting costs due to inefficient architecture.
Our Solution:
- Provided a dedicated team with expertise in the legacy technology to stabilize the environment.
- Conducted a thorough security audit and implemented a rigorous patch management process to eliminate critical vulnerabilities.
- Optimized the infrastructure and implemented auto-scaling to handle traffic surges effectively.
- Reverse-engineered and documented the system while creating a phased modernization roadmap to migrate to a microservices architecture.
Our Support & Maintenance Process
We follow a structured, transparent process designed for seamless integration and maximum efficiency, ensuring you're always in control.
1. Onboarding & Knowledge Transfer
We begin with an intensive KT phase, working with your team to understand your application architecture, business logic, and existing workflows. We set up access and integrate with your tools.
2. Stabilize & Monitor
Our first priority is stability. We deploy our monitoring and observability stack to gain full visibility. We establish a baseline for performance and begin managing incoming L2/L3 tickets.
3. Remediate & Fix
We tackle the most critical issues first, focusing on root cause analysis and implementing permanent fixes. We manage security patching and address immediate performance bottlenecks.
4. Optimize & Enhance
Once stable, we shift to proactive optimization. We provide monthly reports with insights on performance, security, and cost, along with recommendations for enhancements and technical debt reduction.
Technology Stack & Tools We Support
Our teams are proficient in a wide range of modern and legacy technologies, ensuring we can support your specific environment.

Frequently Asked Questions
L2 (Level 2) support handles technical issues that are beyond the scope of L1/help desk. They have deeper product knowledge and can troubleshoot complex problems. L3 (Level 3) support is the highest tier, typically composed of senior engineers and developers who can perform code-level analysis, debug complex architectural issues, and develop permanent fixes (bug fixes).
We work as a seamless extension of your team. We integrate directly into your existing tools, whether it's Slack/Teams for communication, Jira/Asana for ticket management, or GitHub/Azure DevOps for code. We participate in your daily stand-ups, planning meetings, and retrospectives to ensure full alignment.
We offer customized Service Level Agreements (SLAs) based on your specific needs and the criticality of your application. Our SLAs typically cover response times and resolution times for different priority levels (e.g., Critical, High, Medium, Low). We also establish Service Level Objectives (SLOs) for key metrics like uptime, latency, and error rate as part of our SRE approach.
Absolutely. We have dedicated teams with expertise in a wide range of legacy technologies (e.g., older versions of Java, .NET Framework, PHP, etc.). We specialize in stabilizing these environments, providing reliable support, and working with you to create a strategic modernization roadmap to reduce long-term risk.
Security is at the core of our service. We are SOC 2 and ISO 27001 certified. Our processes include regular vulnerability scanning, proactive security patch management, and adherence to secure coding practices. We can also provide support for your specific compliance needs, such as HIPAA or PCI DSS, by ensuring our operations and your application meet the required standards.
Our standard onboarding process takes 2-4 weeks. It begins with a deep-dive discovery and knowledge transfer phase. We then set up all necessary system access and monitoring tools. We typically run in a "shadow mode" for a short period to get familiar with your systems before taking full responsibility. The goal is a smooth, risk-free transition.
