Cover image for Real Estate Website
I created this

Real Estate Website I created this project to explore how a real estate platform could present properties in a way that feels modern, professional, and easy to navigate. The goal was to design a site that puts the properties at the center while still providing a smooth experience for users searching for a home. I started by structuring the website around the user's journey — from discovering properties through the hero search section, to browsing featured listings, learning about the company, and eventually getting in touch. I focused on creating a clean visual hierarchy, using large property imagery, simple typography, and spacious layouts to give the site a premium feel. The website was developed from scratch using HTML, CSS, and JavaScript. JavaScript was used to add interactive features such as the property search and filtering system, favorite buttons, mobile navigation, and scroll-based animations. CSS media queries were also used to make the layout responsive across desktop, tablet, and mobile screen sizes. Key focus: Responsive Design • UI/UX • Front-End Development • Interactive Components Tools: HTML5 • CSS3 • JavaScript

Cover image for GridSense — Smart Energy Monitoring

GridSense — Smart Energy Monitoring Dashboard Project Type: UI Design & Frontend Development Category: EnergyTech / SaaS / IoT Technologies: HTML, CSS, JavaScript, Chart.js Project Overview GridSense is a smart energy monitoring dashboard concept designed to help households and businesses understand, monitor, and manage their electricity consumption through a centralized, intuitive interface. The platform transforms energy usage data into actionable insights, allowing users to track real-time power consumption, monitor connected appliances, estimate electricity costs, and identify opportunities to improve energy efficiency. Key Features - Energy Monitoring: View current power consumption, daily energy usage, and estimated monthly electricity costs. - Appliance Management: Monitor connected appliances, view their power ratings, and interact with simulated ON/OFF controls. - Energy Analytics: Explore electricity consumption trends through interactive charts with weekly, monthly, and yearly views. - Energy Efficiency Insights: View an energy efficiency score and identify potential opportunities to reduce consumption. - Smart Alerts: Receive notifications about unusual energy consumption, prolonged appliance usage, and energy savings. - Responsive Interface: Access the dashboard through a modern interface designed to adapt to different screen sizes. - Dark Mode: Switch between light and dark themes for a more personalized viewing experience. Design Approach The interface combines a clean SaaS dashboard layout with intuitive navigation, data visualization, and clearly structured information. A consistent visual hierarchy, reusable UI components, and a modern design language help users quickly interpret energy data without unnecessary complexity. Development Built using HTML, CSS, and JavaScript, GridSense incorporates interactive dashboard elements, dynamic appliance power calculations, theme switching, and Chart.js visualizations. The project demonstrates the integration of frontend development and UI design principles to create a practical, data-driven interface for a smart energy management platform. Project Goal The goal of GridSense is to explore how thoughtful interface design and accessible energy data visualization can make electricity consumption easier to understand, helping users make more informed decisions about their energy usage.

Headphone 3D Modeling & Rendering
Project

Project: Headphone 3D Modeling & Rendering Project Overview This project involved designing and developing a 3D model of a pair of headphones using Autodesk Fusion 360. The aim was to create a modern, functional-looking headphone design while exploring 3D modeling, form development, and product visualization. Design Development I began by developing the overall shape and proportions of the headphones, focusing on creating a balanced relationship between the headband, earcups, and supporting components. I used Fusion 360's modeling tools to construct and refine the individual parts before assembling them into a complete product. Modeling Process The model was created using a combination of sketches, extrusions, fillets, and other solid-modeling techniques. Particular attention was given to symmetry, proportions, smooth transitions, and the overall appearance of the product. Rendering & Visualization After completing the 3D model, I produced a rendered view to showcase the final design. The rendering allowed me to present the headphones with realistic materials, lighting, and surface finishes, making the final form easier to visualize. Skills Demonstrated: 3D CAD modeling Product design Autodesk Fusion 360 Assembly and component modeling Surface/form development Rendering and visualization Attention to proportion and detail Final Outcome The final result is a complete 3D headphone model that demonstrates my ability to take a product concept and develop it into a detailed digital model. This project also helped me improve my understanding of CAD workflows and product visualization.

Cover image for Tycobrahe Octavia - Guitar Effects

Tycobrahe Octavia - Guitar Effects Pedal PCB I designed a custom PCB for the Tycobrahe Octavia, a distinctive guitar effects pedal known for its unique octave and fuzz-style sound. The project involved translating the circuit requirements into a practical, production-ready PCB layout with careful component placement, routing, and attention to signal integrity. The board was designed for a client with a focus on reliability, clean routing, compact layout, and ease of assembly.

Cover image for IO Board for Raspberry Pi

IO Board for Raspberry Pi CM4 CM4 is a Raspberry Pi s computer module that is without the IO connectors. My job was to Design IO Board for the CM4 in a compact size with onboard 36v Power input support. it was challenging work but after the testing and prototyping of one design, we successfully completed it. The IO (Input Output) PCB supports HDMI Display Port, USB, Audio Output, USB C, and Power Input ports.

I designed a custom PCB integrating an ESP32 wireless module, power management, USB connectivity, switching regulators, and supporting electronic components. The design focuses on reliable power distribution, compact component placement, and practical manufacturability for an IoT hardware application.
