A mobile application designed to help parents monitor and support their child’s growth and development. The platform enables tracking of sleep schedules, meals, medication, and vaccination history, while leveraging AI analytics to provide personalized insights. Parents can also capture and store memorable milestones such as first words, photos, and visited countries, combining practical health management with a digital memory book

• Collaborated with stakeholders to gather requirements and define system workflows;
• Created front-end and back-end architecture;
• Developed React interfaces for tracking and data management;
• Ensured that the design system and front-end implementations meet accessibility standards;
• Worked closely with UI / UX designers to translate wireframes, mockups, and prototypes into functional, interactive interfaces.

Designed and developed a modular AI-native low-code platform that enables users to build fully customized applications and intelligent workflows without traditional programming skills. The system includes a powerful CRM built on top of this architecture, integrated with a web-based AI agent. It allows seamless communication between AI components, empowering non-technical users to design, deploy, and connect AI-driven applications in a unified ecosystem.

• Architected and developed AI-driven platform backend and frontend components to enable low-code application building;
• Implemented a real-time visual workflow builder with UI automation blocks;
• Integrated AI-driven agents to manage tasks, notifications, and validations;
• Built Prototypes and Proof of Concepts.

This is an application like Siri, which helps order dishes from different restaurants like Starbucks, Dominos, etc in one place using voice. Frontend part built on Next.js. Rest backend built on NestJS and a few AWS Lambda functions created using Serverless. The system is automatically deployed using AWS services CodeBuild and CodePipeline.

• Designed project architecture and database structure;
• Built and maintained a scalable design system with reusable components and consistent interaction patterns;
• Led technical aspects of the project;
• Developed prototypes and proof-of-concepts;
• Produced comprehensive documentation.

The main aim of this app is to help hospitality businesses create a work environment that is easy to understand and less stressful. Here you can create an account and check the preparedness of the rooms in hotels/ hostels, assign some issues or rooms/groups of rooms to the staff to solve or make them clean later. Also, you can create different statuses of these issues and prioritize them. There are two different kinds of subscriptions: basic and Proversion. The Pro version gives you access to more perks, using thisapplication.

• Focus on optimizing the performance of the website/application, ensuring fast load times and smooth interactions;
• Implemented key FE and BE functionality;
• Build interactive prototypes and work in an iterative manner to improve the design based on user feedback and testing;
• Technical Leadership of the project.
