Experience

Stomion Assistant

Stomion Assistant is a mobile application in the healthcare industry. The app was developed by order of Armenia's top dental clinic, Stomion. The assistant is used by regular people that can add requests to doctors. The requests include real chats, and the doctor is there to assist them. The same app is used both by people and doctors, with the feature set varying based on account type.

Note: The entire application was designed and developed by me for a client

Oores

This application is the main focus of the same-named startup. Oores is a map-based social mobile platform. The app lets you match with other people by your interests. The central part comes after that - you see your matches on the map and can send location-sharing requests. Oores is focused on instant, real-time meetings and events.

Note: The application belongs to the startup "oores," where I am a co-founder.

Pure Todo

A pure to-do list, as the name suggests. This application was developed with simplicity in mind. The application's UI is user-friendly and done according to Apple's guidelines. The app packs essential to-do list handling features.

Note: I designed and developed the entire application and all its rights belong to me.

Rankee

Rankee is an iOS application used to accommodate a website ranking system. Users can see the ranked websites by stars and can add their reviews. The application is developed using Apple's best practices.

Note: I designed and developed the entire application and all its rights belong to me.

Diet Companion

This mobile application helps you reach your weight goals easily. After receiving data about you from your input or Apple Health, it calculates diet plans for you. If you choose to accept a plan, you can track your progress in the app, entering what you consume manually, while other information (e.g., calories burned) is synchronized from Apple Health.

Note: I developed the entire application for a client, and I have no right to share the App Store link according to the NDA signed between the company and me. Instead, I posted a link containing a short description and some screenshots of the application.

Spelling Wizard

This mobile application is used for spell-checking your text before sending it. The UI is simple, with the main component being the text entry field. Text is marked red on mistakes and green on mistakes that are fixed.

Note: I developed the entire application for a client, and I have no right to share the App Store link according to the NDA signed between the company and me. Instead, I posted a link containing a short description and some screenshots of the application.

Grocery List Manager

This mobile application is used to create and maintain daily, weekly, and monthly shopping lists. The functionality is basic and on point. Everything happens on your device, on the local database. Shopping items have customization options.

Note: I developed the entire application for a client, and I have no right to share the App Store link according to the NDA signed between the company and me. Instead, I posted a link containing a short description and some screenshots of the application.

Cryptomask

Cryptomask is an application that provides a secure way to store your cryptocurrency wallet's private keys and protect them with an easy-to-remember password. Secure storage is based on encrypting the information using a key derived using essential strengthening methods and the user's password. Additional features include autocomplete suggestions for mnemonic phrases and sharing the encrypted data with third-party services.

Note: The entire application was designed and developed by me in the scope of my course work at Russian-Armenian (Slavonic) University. All of the rights to the application belong to the university, as do all of the student's courses works. Therefore, I have no right to share the App Store link according to the NDA signed between the university and me. Instead, I posted a link containing the presentation of the application.

Selfie Helper

This mobile application creates time-lapses by adding a photo of a person or object every day. In the end, all the photos are being connected in a cool progress-showcasing video.

Note: I developed the entire application for a client, and I have no right to share the App Store link according to the NDA signed between the company and me. Instead, I posted a link containing a short description and some screenshots of the application.

ArmorPlus

ArmorPlus is an application used to hire bodyguards. The user interface is based on a map and resembles that of Uber.
