Flagship Project: Fintech Portfolio Dashboard

Stack: Python, Docker, Docker Compose, WSL2, SQL, oLlama (Qwen 2.5 Coder)

  • System Architecture & Isolation: Engineered a containerized, multi-OS financial application using a clean architecture pattern in Python 3.9-slim to minimize deployment overhead and reduce image attack surfaces.
  • Infrastructure & DevOps: Integrated Docker Compose to seamlessly orchestrate isolated backend services, safely decoupling configuration via environment variables for secure database migrations.
  • Local Virtualization: Developed and optimized the local execution environment inside WSL2, leveraging automated local AI agents (with oLlama) for rapid testing, continuous local integration, and infrastructure iteration.
TapeDeck Studio (Commercial Product Case Study)

Stack: Laravel 11, PHP, MySQL, Stripe API, AWS S3

  • Engineering Lead: Orchestrated the technical execution, relational data modeling, and requirement scoping for a production-ready creative media platform.
  • Cloud & Financial Integration: Integrated the Stripe API for secure payment processing workflows and configured AWS S3 buckets for scalable, secure cloud media storage.
  • Lifecycle Management: Established standard engineering workflows, managing weekly production deployment cycles and structural database migrations utilizing Git version control.
Full-Stack Reddit Client

Stack: React, Redux, Express.js, Node.js, REST API

  • State Architecture: Developed a modern client dashboard utilizing React and Redux for centralized, deterministic front-end state management.
  • Secure Middleware Proxy: Engineered an Express.js proxy backend layer to securely handle OAuth authentication tokens and inject secure credentials into outgoing API request headers.
  • Security Optimization: Mitigated front-end data exposure risks by routing secure Reddit API handshakes entirely through server-side middleware, protecting app credentials.
Unreal Engine 5 & C# Mechanics:

Developed proficiency in Unreal Engine 5 and Unity3D, building complex state machines, 3D asset pipelines (Blender), and exploring advanced Object-Oriented Programming (OOP) concepts through interactive game mechanics.
