    • Introduction to TejaSoft’s Embedded Java API/Applications Optimization Services By Raja Nagendra Kumar Founder & C.T.O Made public on 3rd Nov 2009
    • • We are into Specialized Java product services to Software Houses who aim for world class quality at optimum cost and process. • We are a Private Limited (Pvt. Ltd.) company registered with Government of India, Companies act and operational since Dec 2004 and into 5th year of our services • Founder previously employed by Sun Microsystems who was a JSR Compliant Portal Product Architect • Senior team members have over 10 years “hands on” experience • Development Team - 10 members (including Senior Consultants) • Based in Bangalore, India • We live and breath Java and apply the best Software Practices which have direct impact on the code we deliver.
    • Our Specialize Product Services are based on 1. Our Extreme comfort on others code and/or legacy code 2. Aim and Passion for Providing Future Proof Products for enterprises looking for mid term and long term success 3. Aim to prove a Green Zone code for Developers 4. An eye for details backed with deep expertise on building world class java products • We deeply understand the costs associated with going to market with a bug or less features. • We have seen many life cycles in the products 5. Our Technical expertise allows us to get to roots and give you the needed value 6. We are a known company in embedded world though our JavaME and Android Product Services 7. We are known for Crisis Management for startups. 8. We do have in-house products and frameworks (TezzMDF, TezzD, TezzVM) 9. Being focused is the key to our x-ray vision and value in this area.
    • TejaSoft is specialized to provide the following Optimization Services for Embedded Java Applications 1. Architecture and Design 2. Memory Leak Analysis &Profiling 3. Multi threaded applications Performance Profiling 4. Thread Leak, Dead Lock Analysis & Profiling 5. Crash Analysis and Reproducibility 6. Foot Print Size Profiling 7. Code Review and Refactoring for better all 8. Code , Media /Resources Reusability Review across the Products 9. Testability Review 10.Build System Review
    • • Embedded World • CDC/CLDC and associated JSR’s • Implementation and extensions • Compliance Testing • Usage in applications • Usability and Extensions • 3rd party api customization and usage • Android (SDK) • JUnit and J2ME Unit and most other extensions including Mock Testing • Desktop World • Ant Customization • Web 2.0, J2EE Technologies
    • • TejaSoft has experience of seeing/using 100’s of VM implementations, though our mobile applications development on various mobile phones. • We do see Personal Java VM’s would provide different experience but due to constrained and embedded nature, we don’t expect too much deviation. • We have the knowledge base of what kind of issues with each of the manufactures such as Nokia, Motorola, Sony Ericsson etc
    • • J2SE and J2ME Profilers • PMD • JDepend • SonarJ • Code Coverage Tools • Structure101
    • In general you could expect the following results on a Embedded Java Applications . • At minimum 10% performance increase • Reduction in code size by at least 10% on a min of 15,000 lines of code • Reduction in JAR Size and Runtime Memory needs • Improved Reliability with less crashes • 10% more reusable code • At least 15% less if’s in applications • Positive Code Metric • For Reduced Dependency • Reduced Cyclomatic complexity at method levels • Identify Duplicate Codes • Few radical suggestions on alternate approaches and technologies
    • Our association models included • As a 3rd Party Code Auditors • As a Test Automation Team • As a Refactoring Team
    • As a 3rd Party Code Auditors, we provide another view and opinions which could enable better product evolution and road map. • We work closely, with Management, Principal Engineers and Core Developers, hardware and C, C++ teams. • We understand past development and future needs/goals • We Observe the current standards and processes of the development • We understand the Integration layers and its interfaces • We understand product versions and variations based on the similar code base • We understand the 3rd party products and open source products dependency
    • • We go though the code on module by module. Most complex/painful one first • We apply in-house built and popular tools in this area to understand and measure the existing code metric and critical paths • Following our detailed study we come out with our observations, doubts and issues at Module, Class, Method, Relationships and Architecture. • Based on the client technical team discussions and accepted points, we suggest a possible road map for changes • We prefer to do this module by module or application by application • Time span for this kind of engagement could be any where between 8 to 10 weeks
    • As Test Automation Team we give a safety net for your embedded applications • Our focus would be writing the unit, load and performance test suites for the existing code base of CDC/STB applications and VM API Implementations. • We may also decide to write functional test cases and move towards unit tests. • We work with developers and architect in case code needs to be refactoring for better testability • We follow the code coverage and good principles of test case writing for easy and suite level running of the same by developers and build system. • We have expertise to build test cases from zero to 20,000+ tests which just take 10 minutes to test a module. Before this approach it was taking two weeks (Manual testing)
    • As Refactoring Team, we give green code and new fresh life next release • This is recommended approach once we complete the cycle as a 3rd party audit team and Test Automation team. However it is not a compulsion. • By which time, we would have know the product and people and process • We agree upon Refactoring goals in terms of code reduction, complexity reduction and time frames. • We take the code and refactoring ownership and deliver the results • We may write test cases based on backward compatibility needs • We have expertise to convert more than 25000 lines of code in just 5 classes to 200 plus classes (including the test cases) and each class not being more than 200 lines.
    • • Internet Profile and Search • www.linkedin.com/in/nagkumar • My customers and colleagues feedback • Raja Nagendra Kumar on google or Respective Technology forums • Google search for ‘J2ME Bangalore’ to feel TejaSoft’s work on JavaME • Could provide references at CEO level on request.
    • • We depend on Our Experience and Expertise to give you value rather than being focused around tools • TejaSoft (since its inception) is by strategy focused on the Immense Code Optimization, Reusability and Quality. This has deep and specialized expertise matching to your current needs. • In an environment where Management is expecting and supporting, we are sure to give you results that would be visible to entire team and decision makers. • We could guarantee results unlike any others.
