Individual Projects

Two independently developed products connecting application architecture, data and user experience. Explore the engineering work and the applications below.

01 / Individual Project

VanirasAI and Machine Learning Stock Forecasting

Independent Developer

I independently designed and developed Vaniras, an AI and machine learning project for stock forecasting and financial research. I owned the work from architecture and implementation through deployment and product delivery, connecting the forecasting workflows with a complete web application.

  • Python
  • XGBoost
  • Node.js
  • Next.js
  • TypeScript
  • AI / ML
  • Financial Research
Read full description: Vaniras | AI and Machine Learning Stock Forecasting
Individual Project

The project brings together data processing, machine learning pipelines, model evaluation and forecast APIs. My work covered both the forecasting-related functionality and the application layers needed to make its outputs available through backend services and a user-facing product.

I worked with Python and XGBoost for machine learning, Node.js for backend development, and Next.js with TypeScript for the web application. The engineering scope connected data workflows, model outputs, APIs and frontend implementation rather than treating the model and the interface as unrelated deliverables.

Vaniras demonstrates independent product ownership across applied machine learning and full stack development, including architecture, integration, evaluation and deployment for a financial research product.

Life WorldReal Estate Marketplace

Independent Developer

I independently developed Life World, a real estate marketplace focused on property discovery and a clear browsing experience. The product brings property information, search and listing presentation into a single application, helping visitors explore homes and compare the details that matter to them.

  • Next.js
  • JavaScript
  • TypeScript
  • MongoDB
  • Real Estate
  • Marketplace
Read full description: Life World | Real Estate Marketplace
Individual Project

I worked with Next.js, JavaScript, TypeScript and MongoDB, connecting the web interface with the application's property data. My contribution combined application implementation with the presentation of structured information, including property details and the browsing flows around them.

The public experience supports searching by location and property type and presents listing information such as images, amenities and pricing. The product connects the initial browsing experience with the detailed information visitors use to compare individual properties.

Life World demonstrates my independent work across a database-backed web product, from the application structure and data integration to the user-facing experience. It complements Vaniras by showing full stack development in a marketplace setting rather than a machine learning product.
