• From 2018 -2019 : I worked for a client called Tractor Supply , which is a major retail chain and was able to design and develop a mobile point of sale system app which can work in tandem with multiple card readers like verifone and Ingenico. The App had multiple features for searching an item and check for availability , entering an item , checkout which has multiple payment options like debit, credit gift card and installments and receipt issuance. On top of the encryption of the card readers , I have been able designed an encryption algorithm which made the entire process safe.
• From Jan 2019 - May 2019 : I worked for client called Carefirst(Blueshield of Maryland ) member facing App which is a hybrid app of react code iOS/ cocoa working on top of it encapsulating the react pages in a web view using the WKwebview framework. I have worked in a few things like introducing the WKwebview framework to minimize app crushes since previously the app was using the UIWebview class. and was susceptible to app crash considering the react code is used by the web and android at the same time..
• From may 2019- Jan 2023 : I worked for a client called BSCA (Blueshield of California ). I worked on their member facing Apps and worked almost all the features of the App like the dashboard,claims, Explanation of Benefits and Explanation of Coverage and so on. I have designed and developed from scratch new features like full stack payment feature using fiserv APIs as a payment processing partner. It has features like make a payment, auto payment, billing history, wallet, payment status and payment info which is accessible from multiple access points in the App. I have designed and developed the radiant logic Ping identity management to the app which has features for Registration, login, forgot password, forgot username, reset password and the likes. I have designed and developed on multiple re skin and navigation UI/UX implementations.
• From Jan 2023 - current I am working with a client called Millenium Trust Company(Inspira financial)health and wealth management company . I have designed and developed on their payflex health fund product client customized apps using Adobe content and theme management (AEM) which makes the app customizable for their specific client who subscribed its employees to their payflex App. The customization includes the theme , content, fonts and app components like buttons , views and so on

Working as a Lead IOS developer in the applications customized for each e touches clients of which contents like data, color and theme are managed from a content management system. My role involves in designing, creating and maintaining modules and features for the master app code base which is highly customizable generating in accordance to client's needs applied from the content management system web site. At the same time I had the responsibility of maintaining and overlooking modules for the android version ,XCODE is the IDE I use for developing the IOS code and objective c was the language
I was using mostly objective c and swift for a few of the new features . Regrading version controller and work flow I used the Atlassian package of Jira for ticket management ,stash for branch management and confluence for documentation .Git is the version
control I am using to collaborate with other developers. Jenkins for generating ipa and Apk. In the case of the Android I am using the
android studio IDE and java as a language of development. Till I left the company roughly I have been involved
with almost 500 apps for more than 100 clients in submitting and updating generated
customized apps to the App store.

Co-founder and iOS developer in a health and fitness company. I have developed and designed with a team a fitness game app called 'fitness face off'. The app counts steps from step counting device the user is using (‘fitbit’,’jaw bone’ or the Phone ’s built in chip) which were
hosted in the platform of ‘Validic ’, a company which provides the RESTful API service for retrieving the steps. The steps retrieved were converted into coins which were spent to engage between users on buying attacks against each other and armor purchase for protecting their castle. Besides I worked in the design and full development of Apps called 'Nurse Assist' and 'schedule me 'which were specifically created an built for a couple of hospitals.

Developed and designed Apps like ’Printicular’ ,’ iartview’ and ‘Aqua’ within a team . ’Printicular’ is the most successful photo printing App developed to print photos from the user's phone or photo sharing platforms like '500px'or 'box' to Walgreen’s or Walmart's platform for
printing photos on their remote printing machines situated in any Walgreen or walmart. .’iartview’ is an App which helps to see how an art piece looks like on a wall in a particular photo of a room or in a
template room. I have developed on ‘parse’ platform as a back-end for the art pieces database. ’iartview’ has been developed and customized for famous galleries as ‘Sotheby's ’ and ’Shwartz’ . ‘Aqua’ is an app that uses the Blue tooth Low Energy framework to detect an
accessory device which is equipped with low blue-tooth chip and browse through the different registers to check for characteristics read, write, notify or a combination of each and subsequently if it is wite enabled You can send a specific hex instruction code which will be decoded into action on the receiving side. By customizing this general purpose testing App we have been able to control an in house developed vibrating device which is used as an invisible blind person's cane. We were able to change the range of the invisible infrared cane by making it shorter or longer which accordingly vibrates after reflecting back from a flat surface.

Worked on Identification, verification of high end electronic components. Generating test vectors , pin prints and perform different tests like IV test and all for all kind of components which include IC like FPGA, CPLD and PLAs,AD converters and so on ,At the same time creating data
base of pin prints which is used for identification of original parts and for stub matching and comparing signal amplitudes so that accordingly a circuit designer choose his components(since there are same functionality IC with the same or similar part number but different manufacturer and date code ). Designed, developed and patented as a team an automated system for a DPA(Destructive physical Analysis) of an IC (Integrated circuit) to avoid counterfeiting . I have Participated as a member of a team on the development of a road speed limit radar detector device prototype.
