Portfolio

A detailed 3D sci-fi weapon created with hard-surface modeling techniques. The design features mechanical components, cylindrical energy systems, armored panels, exposed machinery, and intricate surface details. The model was rendered with a green and metallic material combination to emphasize its futuristic industrial aesthetic, with studio lighting and a textured background used to showcase the form, materials, and overall design.

Architectural Rendering

Converted a provided 2D design into a precise 3D CAD model and generated a production-ready STL file for 3D printing and manufacturing applications.

The work involved interpreting the 2D reference geometry, recreating the required dimensions and features in a 3D environment, developing the solid model, and exporting the final geometry as an STL file. Particular attention was given to dimensional accuracy, geometry integrity, surface quality, and ensuring the model was suitable for reliable STL export and downstream 3D printing.

Key Responsibilities
Reviewed and interpreted the provided 2D design/reference drawing.
Recreated the design as an accurate 3D CAD model.
Applied the required dimensions, profiles, holes, curves, and geometric features.
Checked the model for proper geometry and overall dimensional consistency.
Prepared the final 3D model for STL conversion.
Exported and delivered the final STL file for 3D printing/manufacturing.
Ensured the exported STL was clean, accurate, an

I created a detailed 3D model and photorealistic visualization of a 6-metre lighting tower with a concrete base. The completed project includes four high-quality rendered views from different angles and a polished 10-second fly-around animation. Particular attention was given to accurate proportions, realistic metal and concrete materials, fine construction details, professional lighting, and natural shadows to achieve the required industrial appearance.

3D Render and Animation

Designed and delivered a high-quality educational simulation of a hybrid renewable energy system inside SimulIDE, powered entirely by an Arduino-controlled sketch. The project demonstrates how solar panels, wind turbines, and tidal generators can work together on a shared 12.8V DC bus, with the Arduino reading simulated voltage/current inputs and automatically prioritising energy sources using relay/MOSFET switching logic.

The simulation was built to be visually clear and classroom-friendly, focusing on component interaction, control logic, and system behaviour rather than industrial-scale optimisation. It includes:

-Integration of solar, wind, and tidal energy sources
-Arduino-based decision logic for source prioritisation
-Voltage/current sensing for each energy input
-Switching control using SimulIDE-native components
-Live simulation feedback to show load sharing and source changes
-A reproducible project package with circuit file, Arduino code, and documentation

Renewable Power System Simulation

I managed the Week 1 technical infrastructure setup for a UK B2B SaaS fleet-management project during its staging phase.

My work included configuring Namecheap DNS and Google Workspace email infrastructure, including MX, SPF and DKIM authentication, resolving email delivery issues, and provisioning the HubSpot CRM environment. I also created five custom fleet-management CRM properties, configured validation rules, and added a reusable annual SaaS licence product to the HubSpot Product Library.

During the project, I also identified important HubSpot data-validation limitations affecting API and bulk imports and helped define clear technical and compliance boundaries around payment infrastructure and company-registration responsibilities.

The completed infrastructure was reviewed and accepted by the client, and the project milestone was successfully released.

B2B SaaS Infrastructure & CRM Operat

In this project, the goal was to create a standalone macOS application from a Python script. The following steps were undertaken to achieve this:

Initially, PyInstaller was chosen to package the Python script into a standalone macOS application. PyInstaller is a popular tool that bundles Python applications along with their dependencies into a single executable for various platforms, including macOS.

After installing PyInstaller and attempting to create the application, an error occurred, leading to the exploration of alternative solutions, such as cx_Freeze and the BeeWare project's briefcase.

Despite exploring other options, it was ultimately decided to continue using PyInstaller. Necessary adjustments were made to resolve the error encountered earlier, ensuring that the standalone application was successfully created with PyInstaller.

With the PyInstaller issues resolved, the Python script was bundled with its dependencies into a .app file for macOS.
