Engineered Projects
A selection of technical challenges where I solved for scalability, performance, and reliability.
ScholarSync: .NET Core Engine
Complete overhaul of a legacy C# WinForms application to a distributed .NET Core architecture. Engineered a data migration pipeline using EF Core that reduced query latency by 65% and supported 5x concurrent users.
Content2Social AI
WordPress automation engine integrating OpenAI/Gemini. Implemented complex rate-limiting logic and a queuing system using Redis to handle massive content spikes without API throttling.
ScaleStore: Distributed Commerce
A high-availability e-commerce engine built with Django. Leveraged Celery for asynchronous task processing and Redis as a primary cache layer to ensure sub-100ms response times for product catalogs under high load simulations.
Professional Experience
cat /var/log/career.logBackend Software Engineer @ Academic
- >System Overhaul & Migration: Engineered the architectural evolution of legacy desktop management tools into modern, distributed web environments. Successfully transitioned systems from C# WinForms to a unified .NET Core and Entity Framework Core ecosystem, enforcing strict data normalization protocols.
- >
- >API Design & Optimization: Architected and deployed production-ready RESTful APIs utilizing Node.js (Express) and Python (Django REST Framework), implementing optimized query execution paths and relational schema constraints.
- >
- >Distributed Task Management: Designed high-availability system blueprints incorporating Celery for asynchronous background processing and Redis for distributed event caching to mitigate bottlenecking during peak data ingestion.
- >
- >Database Engineering: Conducted advanced data tiering and performance tuning using PostgreSQL and Drizzle ORM, engineering multi-table relational schema constraints and optimized JOIN operations to minimize query latency.
Freelance Technical Content Writer @ Independent / Freelance
- >Deep-Tech Communication: Authored comprehensive developer documentation, architectural breakdowns, and implementation guides focusing on complex systems engineering.
- >Low-Level Systems Coverage: Produced highly technical analysis on the Linux kernel architecture, compiler operations (including lexical analysis scanners), and multi-threaded memory management protocols.
- >Technical Accuracy: Translated sophisticated database management properties, concurrency control mechanisms, and distributed systems architecture patterns into precise, accurate, and actionable guides for engineering teams.
HR Professional (Corporate Operations) @ Independent / Freelance
- >Engineering Talent Alignment: Synthesized dual competencies in technical development and corporate operations to bridge communication gaps between engineering teams and business stakeholders.
- >Process Optimization: Implemented operational strategies to streamline cross-functional workflows, enhance organizational clarity, and manage resource allocation for technical projects.
