Build Modern Applications. Modernize What Matters.

Design, develop, modernize, integrate, test, and support applications that are cloud-ready, user-first, secure, and built for faster business change — across the full application lifecycle.

Your applications are holding your business back.
And the cost of standing still keeps rising.

Legacy platforms, fragmented integrations, slow release cycles, and mounting technical debt are consuming IT budgets and blocking digital initiatives. The challenge is no longer whether to modernize — it is how to do it without disrupting the business that runs on today’s systems.

Legacy Debt

Outdated monolithic architectures and unmaintainable codebases slow every change, raise risk, and consume disproportionate maintenance effort.
hourglass-start

Slow Releases

Manual SDLC, disconnected testing, and absent CI/CD pipelines mean business change takes months — not days.

 

 

lead-management

Poor User Experience

Users expect seamless, intuitive digital journeys. Legacy UX and brittle front-ends drive low adoption and shadow IT.

Integration Gaps

Disconnected systems limit data flow, process speed, and the ability to deliver consistent experiences across channels.

Every application need. One delivery model.

Product Engineering mindset. Enterprise delivery discipline.

Most application services providers offer either development or maintenance — not both, and rarely with the IP and accelerators to compress delivery timelines. 3i Infotech’s ADMS model combines a full-lifecycle delivery capability with proprietary platforms, a Shift-Left quality engineering discipline, and proven modernization frameworks that de-risk complex legacy transformation programmes.

Full Lifecycle in One Model

From greenfield development and legacy modernization through API integration, DevOps delivery, QA automation, and 24x7 managed support — one partner, one operating model, no handoff gaps.

Proprietary Accelerators

Flexib+, API CoE, NuRe platforms, and a purpose-built automation stack reduce delivery time, lower risk, and improve quality outcomes across every engagement — not just methodology.

Shift-Left Quality Engineering

200+ QA and automation specialists embed testing, security, and performance validation into the CI/CD pipeline from day one — delivering 95%+ automation coverage for critical business workflows.

AI & Platform Engineering

Microservices, Kubernetes, serverless architectures, and AI/ML integration capabilities that rebuild monolithic systems into cloud-native, independently scalable platforms.

Everest Group Recognized

FAQ

What is Application Development, Modernization and Support (ADMS)?
ADMS is an end-to-end application services model that covers custom application development, legacy modernization, API integration, DevOps delivery, QA automation, and managed application support — all under one operating framework. 3i Infotech’s ADMS model is built on a Product Engineering mindset, designed to help enterprises build new applications, modernize existing ones, and operate both continuously.
What does application modernization mean and how does 3i Infotech approach it?
Application modernization is the process of updating legacy applications to improve performance, scalability, maintainability, and cloud-readiness. 3i Infotech’s modernization path covers four approaches: Move (cloud migration), Optimize (performance and stability improvement), Extend (new APIs and capabilities), and Automate (embedding DevOps and testing). The approach is selected based on each application’s business criticality, technical complexity, and modernization ROI.
What is Flexib+ and how does it improve application quality?
Flexib+ is 3i Infotech’s proprietary test automation platform that delivers digital-first QA across web, API, mobile, visual, performance, and security testing. It is embedded into CI/CD pipelines to enforce Shift-Left testing — ensuring quality, security, and performance are validated throughout development, not just at release. It delivers 95%+ automation coverage for critical business workflows.
What is Application Management and Support (AMS)?
AMS is 3i Infotech’s managed application operations model — providing 24×7 L1, L2, and L3 support, SLA-based incident management, proactive monitoring, and root cause analysis for enterprise applications. AMS clients benefit from a structured governance model, continuous improvement processes, and a single point of accountability for application performance.
How does 3i Infotech deliver API integration and system connectivity?
3i Infotech’s API integration capability is anchored in an API Centre of Excellence (API CoE) — a reusable framework of reference architecture, integration patterns, DevOps-integrated delivery, and governance controls. This enables API-led connectivity across legacy systems, cloud platforms, mobile channels, and enterprise applications like Salesforce, SAP, and core banking systems.
Can 3i Infotech support both cloud-native development and legacy platform modernization simultaneously?
Yes. 3i Infotech’s ADMS model is designed for exactly this scenario — running new cloud-native development alongside active legacy modernization programmes without disrupting operational systems. The Assess → Design → Build → Run framework sequences modernization safely, with the managed support layer keeping existing applications stable throughout.
What industries does 3i Infotech serve with ADMS?
ADMS is deployed across BFSI, capital markets, healthcare, retail, supply chain, and enterprise software. The practice is particularly strong in BFSI and fintech — where complex legacy estate, regulatory compliance requirements, and the need for API-led integration at scale are most acute.
What recognition has 3i Infotech received for application automation?
3i Infotech has been recognized as an Aspirant in Everest Group’s PEAK Matrix® Application Automation Services Assessment 2023 — an independent validation of the organization’s automation capability, delivery track record, and market positioning in the application services space.
