Corrective Maintenance
We triage and fix production bugs under defined SLAs, with critical issues acknowledged within 1 hour and resolved on priority tracks. Root-cause analysis accompanies every fix so the same defect does not return.
Custom Software
Software Maintenance & Support
Keep your software secure, fast, and always up to date.
Our dedicated support teams handle bug fixes, security patches, performance tuning, and feature enhancements — with SLAs you can count on.
Our Offerings
Software Maintenance & Support Services We Provide
Preventive Maintenance
Scheduled health checks, dependency updates, and database optimization keep small issues from becoming outages. We patch security vulnerabilities within days of disclosure, not months.
Performance Optimization
We profile slow queries, memory leaks, and bottlenecked endpoints, then tune them with measurable before-and-after benchmarks. Clients typically see 30-60% faster response times within the first optimization cycle.
Security Patching & Compliance
Continuous vulnerability scanning, OWASP-aligned hardening, and timely patching keep your application audit-ready. We maintain compliance posture for HIPAA, PCI DSS, and GDPR-regulated systems.
Feature Enhancements
Beyond keeping the lights on, our maintenance teams ship new features and improvements from your backlog every sprint. The same engineers who maintain your system build on it, so context is never lost.
24/7 Monitoring & Incident Response
Proactive monitoring with Datadog, Grafana, or CloudWatch alerts our on-call engineers before your users notice a problem. Monthly reports show uptime, incident history, and resolution times in plain language.

How We Work
What You Get In Writing
Terms that go into every agreement we sign. See all client commitments.
A Written Price Before Work Starts
Every job gets a scope and a number in writing first — a fixed price for defined work, or an hourly rate with a capped estimate. If scope changes, we re-quote before we build, not after.
You Own the Code
Source code, designs, and data are yours. We work in your repository where possible, hand over full documentation, and transfer everything at the end. No license fees, no hostage situations.
NDA Before You Share Anything
We sign your NDA — or send ours — before the first technical conversation. Your idea, your data, and your customer information stay confidential during and after the engagement.

Yes — roughly half of our maintenance clients come to us with someone else's codebase. We audit the code, set up monitoring and CI/CD if missing, document what we find, and take ownership within 2-4 weeks.
You do. All patches, refactored code, documentation, and monitoring configurations belong to you, and everything lives in your repositories and cloud accounts from day one.
Yes, 24/7 support is standard on our higher tiers, with on-call engineers covering all time zones from our Ahmedabad headquarters. Many of our 10+ global clients run mission-critical systems on exactly this model.
