Projects
Featured Work
Architected a real-time event-driven microservice system in Python using FastAPI and WebSockets, establishing bidirectional connection lifecycles with under 200ms latency. Developed vector-search RAG retrieval pipelines in ChromaDB with optimized document chunking, achieving a 40% improvement in context relevance. Fully containerized with Docker.
Under 200ms inter-agent latency · 40% RAG relevance improvement · 4-minute containerized deploys
Built a 6-tool B2B automation suite — Friction Auditor, Pitch Builder, Margin Calculator, Legal Vault, Dashboard, and Operator Mode — that audits business workflows and deploys middleware automations. Connects HubSpot, Twilio, and Clearbit APIs, saving clients 18+ hours/month and boosting conversion rates.
18+ hours/month saved per client · 35% increase in lead-to-call conversion · 6 integrated tools
Engineered a Java scheduling application applying OOP principles to map 50+ subject categories and 800+ entities. Normalized database schemas in MySQL to 3NF and utilized JDBC to enforce transaction boundaries and database integrity. Implemented backtracking search and constraint propagation to resolve scheduling resources efficiently.
Maps 50+ subject categories · 800+ entities mapped · reduces admin overhead by 38 hours per semester

Design and Implementation of a Constraint-Satisfaction Scheduling Engine for Academic Examinations
International Journal of Computer Science & Engineering (IJCSE) · Vol. 13, No. 2, 2025
This paper documents the design methodologies, constraint propagation algorithms, and backtracking solvers implemented for the EXAMINER scheduling project. It analyzes heuristic efficiency, search space reduction, and validation techniques used to produce optimal examination timetables under complex academic constraints.
