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

3i Infotech brings application development, modernization, API integration, platform engineering, DevSecOps, AI-assisted engineering, and managed support into one accountable model. Build new, reshape legacy, connect the estate, and run it with continuous improvement long after go-live.
Accountable engineering outcomes, not headcount deployment.
Custom Application Development

Web, mobile, product, and cloud-native applications engineered for performance and scalability. Governed low-code delivery accelerates business-facing applications without sacrificing architecture.

Outcome: New digital capability shipped fast, built to stay maintainable.

Application Modernization

Application/Portfolio Assessment, Evidence Assessment, Application Scorecards, Cloud Readiness, Application Health, Technical Debt Analysis, and Transformation Blueprints, prioritized by business criticality and risk.

Outcome: A cloud-ready, API-ready application estate transformed with minimal disruption to business operations.

Application Management & Support

24x7 L1, L2, and L3 managed support with SLA-led operations, proactive monitoring, incident management, and structured root cause analysis.

Outcome: Fewer repeat incidents, faster resolution, and run costs brought under visible control.

API & System Integration

API-led connectivity across enterprise systems, platforms, and channels, anchored in an API Centre of Excellence with reference architecture, reusable patterns, and lifecycle governance.

Outcome: A connected, composable estate with consistent data flow across channels.

Platform Engineering

CI/CD tooling, GitOps, Infrastructure as Code, SRE practices, and observability engineered into shared delivery platforms that give teams paved paths to production.

Outcome: Engineering teams ship faster, with less friction and more control.

DevSecOps

Automated pipelines with security, quality, and release controls built in from Sprint One. Secure coding, automated gates, and Shift-Left validation replace late-stage security scrambles.

Outcome: Vulnerabilities surface when they are cheapest to fix. Releases become routine.

Digital Experience Engineering

User-centred UI/UX for web, mobile, and portal experiences, designed around journeys, usability, accessibility, and adoption metrics, not interface aesthetics alone.

Outcome: Applications users adopt willingly, reducing training overhead and shadow IT.

AI-Augmented Engineering

AI tooling accelerates development, code review, and testing under defined governance, while AI-enabled features such as recommendation, personalization, and natural-language interfaces add product intelligence.

Outcome: Measurable speed and quality gains, with engineering control retained.

Tools and platforms that compress delivery time and reduce engagement risk.

Reusable frameworks, delivery patterns, and reference architectures, brought into every engagement to reduce build effort and de-risk modernization.

NuRe Flexib+

TEST AUTOMATION PRODUCT

Digital-first test automation across web, API, mobile, visual, performance, and security testing, embedded into CI/CD pipelines to strengthen Shift-Left quality. Delivers 95%+ automation coverage for critical workflows.

API Centre of Excellence

INTEGRATION FRAMEWORKS & GOVERNANCE

Reference architectures, reusable integration patterns, lifecycle governance controls, and DevOps-integrated API delivery for connected, composable application estates.

Liferay Practice

PORTAL & DIGITAL EXPERIENCE

Deep Liferay capability across portal development, CMS, migration, personalization, performance tuning, and ongoing support for digital experience platforms.

Modernization Platforms

ASSESSMENT TO ARCHITECTURE

Assessment templates, technical-debt mapping, pathway selection, reference architectures, and reusable engineering patterns that structure the modernization journey.

Product Engineering mindset. Enterprise delivery discipline.

Application programmes fail when development, modernization, integration, quality, and support are treated as separate transactions. Our model brings them together, with shared engineering standards, reusable assets, and accountability that continues after go-live.
Full Lifecycle Ownership
From greenfield development and legacy modernization through integration, DevSecOps, and 24×7 managed support, one partner owns the application lifecycle with no handoff gaps.
Product Engineering Mindset
Applications are managed as evolving business assets, with roadmaps, architecture decisions, adoption measures, and continuous improvement, not as maintenance contracts.
AI-Augmented Engineering
AI assists development, code review, testing, and feature engineering under defined governance, with value measured against speed, quality, and control.
DevSecOps from Sprint One
Security, quality, and release controls are built into delivery from the first sprint, when issues are fastest and least expensive to resolve.
Managed Support Continuity
SLA-led operations, monitoring, release management, and improvement governance continue after go-live. The engagement does not end at launch.
Accelerators, Not Just Methodology
Reusable frameworks, API patterns, modernization playbooks, and NuRe Flexib+ reduce avoidable effort and improve delivery consistency across engagements.

Common questions about Application Engineering.

What is Application Engineering?
Application Engineering is 3i Infotech’s full-lifecycle model for application development services, application modernization, API integration, platform engineering, DevOps and DevSecOps, and managed support. It helps enterprises build new applications, modernize existing estates, and operate both continuously.
What does Application Development, Modernization and Support cover?
It covers custom application development, legacy application modernization, API integration services, cloud-native application development, DevSecOps, and Application Management and Support. These capabilities are often searched as ADMS services and are delivered within the Application Engineering Centre of Excellence.
How does 3i Infotech approach legacy application modernization?
Each application is assessed for business criticality, technical condition, dependencies, and return. The recommended pathway may be to move, optimize, extend, automate, retire, or leave the application unchanged. Modernization is sequenced to protect operational continuity.
Can cloud-native development and legacy modernization run at the same time?
Yes. New cloud-native application development and active legacy modernization can run in parallel. The Assess, Design, Build, Run framework sequences change safely while the managed support layer keeps existing applications stable throughout.
What is Application Management and Support?
Application Management and Support provides SLA-led L1, L2, and L3 application support services, proactive monitoring, incident management, root cause analysis, release support, and continuous improvement for business-critical applications.
How does 3i Infotech deliver API integration services?
Through an API Centre of Excellence: reference architecture, reusable integration patterns, lifecycle governance, and DevOps-integrated delivery across legacy systems, cloud platforms, mobile channels, and enterprise applications such as Salesforce and core banking systems.
How are quality and security built into delivery?
Shift-Left testing, secure coding, automated quality gates, and DevSecOps controls are embedded from the first sprint. Deeper testing and quality-transformation services are available through the Quality Engineering CoE and the NuRe Flexib+ test automation product.
What engagement and delivery models are available?
Fixed price for well-defined modernization and platform builds, time and material for evolving agile development, and managed services for ongoing application operations. Delivery can be onsite, offshore, or hybrid, with follow-the-sun coverage for continuous support across regions.
What happens after go-live?
Managed support continues with SLA-backed operations, monitoring, release management, and a continuous improvement roadmap. The application is operated as an evolving asset, not handed over and forgotten.
