We offer end-to-end product engineering services that help our customers to constantly innovate, gain a competitive edge over new / existing products available in market and optimize time-to-market - at reduced costs.

Our product engineering capabilities can be split into five key categories

Product conceptualization is the key to transform product vision into reality.

We provide end-to-end consulting services on Software Product Conceptualization / Ideation, Design & Prototyping which includes,

  • Market Research
  • Trend Analysis

  • Assess Existing Products
  • Gap Analysis
  • Non-Functional Prototype (Wireframes, Designs, etc.)
  • Technical Architecture Design
  • Database Architecture Design
  • Deployment Architecture Design
  • Proof of Concept (if required)

Based on the product concept, design & prototype, we take it to the next phase - that is product development & testing.

Backed by our vast experience & expertise in diverse platforms & technologies, we provide application development services that meet our customer's requirements in terms of quality, cost and timeliness. We provide the following development & testing services:

  • Product Development
  • Localization / Globalization
  • Release Management & Deployment
  • Test Strategy
  • Product Testing - Functional (Unit, Integration, System, User Acceptance, Regression, User Interface & Usability - Testing)
  • Product Testing - Non-Functional (Installation, Security, Load & Performance, Localization / Globalization, Cross-browser, Cross-platform - Testing)
  • Test Automation

Once the product development is finished and the product goes LIVE, we are there to ensure it continues to serve your company / your customers at peak performance levels all time. Our team is available round the clock to solve any issues that may crop up OR answer any questions you or your team might have along the way. We provide the following sustenance & support services:

  • Product Bug Fixing & Support
  • Sustenance Engineering (Hotfix, Updates, Service Packs, etc.)
  • Enhancements & Performance Tuning
  • Migration & Porting
  • Certifications
  • End of Life Services

Products become obsolete with time - efficiency starts deteriorating, security comes under scanner, product performance is questioned with growing customers' expectations, etc. With the rapidly evolving technologies and business needs, it is high-time that businesses start re-engineering existing applications with new and improved tools and technologies for better business outcomes, better efficiency, and for staying ahead of the competition. We provide the following re-engineering services:

  • Migration (From lower version to higher)
  • Porting (From one technology stack to other)
  • Re-Architecting
  • UX / UI Re-Engineering
  • SMAC (Social, Mobile, Analytics & Cloud) Enablement
  • Product Integration

A product is only as good as its user(s). And to ensure that users get the most out of the product or service, we provide quality training and documentation, materials and collaterals created by our team of technical writers, who are engaged early during the overall product lifecycle. This helps our customers to share their training documents with their customers, channel partners, etc. We provide the following training & documentation services:

  • Architecture and Design Documents
