    Android app, iPhone app, cross-platform app, GPS app, web services…you name any term of mobile and I will not say no to it. With extensive experience in the mobile industry for over 6 years, I have experimented on the oldest and the latest of the technology. I am a tech-savy from childhood which can be reflected through my qualification. I have graduated in Computer Applications and then post-graduated in the same. After my studies I got placed in an IT company where I worked for 2 years but I was not able to enhance my Skills and project my capabilities fully. So, I became a full-time freelancer. I am a workaholic and can never refuse work as it is my utmost priority. I often have to work against the clock to meet deadlines during the busy season but that pays off always. With such vast scope of mobile apps, I have made apps for almost all the major domains as listed below: 1) Photo Editing app (iOS, Android) 2) Traveling App (iOS, Android) 3) Food and Beverages App (iOS, Android) 4) Social Media App (iOS, Android) 5) Utility/E-commerce App (iOS, Android) 6) Real Estate App (iOS, Android) 7) Taxi App(iOS, Android) 8) Health Care App (iOS, Android) 9) Dating App (iOS, Android) 10) Emoji Keyboard App (iOS, Android) TECHNICAL SKILL SET Front-end Languages: Objective C, Swift, JAVA, HTML5, JavaScript Back-end: SQLite, MySQL, SQL Server Web Services: JSON, SOAP Project Management Tools: Basecamp Task Management Tools: JIRA, Trello, Teamwork ANALYTICAL SKILL SET Research Oriented: The projects which are at a nascent stage of conceptualization require lot of deliberation and expert consultancy. I offer the consultancy and the MR services as well on such kind of projects. Process Driven: I adopt a step-by-step process in development. This helps me write clean and optimized codes. Updated With Recent Technologies: It is possible that the technology you are expert at today may turn obsolete tomorrow. So it is always better to keep yourself updated with the recent technologies. I keep myself abreast with the latest developments in mobility solution ecosphere. Fluent communication skills and good inter-personal skills complete me as a full package of developer. I love to make long-term relationships and never let my clients complaint because of the superior quality I deliver as an end-product.
