  • Cialfo

    Cialfo is on a mission to transform the higher education landscape through AI-driven solutions that simplify the college application and career guidance process. Students, counselors, parents, and university representatives use this app to dream, plan, and achieve their goals.

    I took ownership of two major user-side features, ensured that any change to the app affected these two features, and improved the user experience.

  • Reconnect Care

    Reconnect Care simplifies access to detailed health information to put the patient in control. With access to easy-to-understand, real-time information, patients can make better choices and build relationships directly with healthcare professionals they feel comfortable with.

    I added additional features during the early stage of the project, making it more user-friendly and reliable.


    A platform calculates a company's value and structure to make it easier for investors to decide about investing in the right company. It has data points by category and set values from public platform texts.

    I added an automation process for fetching values of data points and generating reports with new values. We defined a set of data points and categories for a specific group of companies to enable scheduling a job.

  • Hinterview

    A platform that provides all components a recruiter might need, such as video interviews with recording features, sending questions to candidates and getting answers, sending profiles to end clients for approval, and updating the hiring status.

    I added features, fixed bugs, debugged issues on a production server, contributed to the team, conducted code reviews, and released the platform according to sales targets.

  • KidzWorld

    A social media app for kids to get updates about their education. It is a platform that enables users to find other students and connect with them and provides quizzes, entertainment, study materials, games, and sports-related knowledge. It has features like sending friend requests, chats, messages, and notifications.

    I was the only developer working on this product for four months, after which I became a leader of a team of six developers, a UI/UX developer, and a QA. I oversaw requirements and deliveries, developed new features, guided the team to achieve the target, and debugged and fixed the issues before they affected the platform's user experience.

  • GetCnergy

    A project to manage real-estate activities, such as adding members and collaborators and assigning tasks. It allows the owner to manage the property state and see the criteria for selling. The platform's back end is built with RoR, and the front end is with Angular.

    I started from scratch and added REST APIs with JSON responses, worked on implementing front-end flows using Angular, and led a team of four, including one Angular developer.

  • Cell Nuvo

    A platform where users can register and access advertisements and surveys to earn credits and spend them per their needs on calls, SMS, and data plan activations.

    I handled the activities of a middleware server that provided API to a mobile app and accessed other third-party APIs to get service.

  • Impact Health Platform

    A platform where users could search and select health insurance plans according to their location, age, and treatments.

    I wrote test cases, integrated the contacts list from Google and Yahoo, added features from the landing to the checkout page, and implemented Stripe for payment. I also fetched data from XML and PDF with hundreds of different structures and imported them into the database.

  • Breitenbush Hot Springs

    I migrated a resort reservation system from Ruby 1.8.7 and Rails 2.3.18 to Ruby 1.9.3 and Rails 3.2.21. It is a one-side application, meaning only the office can make and cancel reservations.

    I also was a part of the team developing a customer-side application. We implemented API to use all features of the existing application.
