(01)

Full-Stack Development

I build complete web applications from frontend to backend. Using Python FastAPI for robust APIs and React/Next.js for responsive interfaces, I deliver full-stack solutions that scale.

Full-Stack Educational Platform

AI Tutoring Platform

Full-Stack2025

Challenge

Students needed personalized, on-demand tutoring support that could adapt to individual learning paces and provide instant feedback on code submissions.

Solution

Built a full-stack platform with FastAPI backend exposing RESTful endpoints, Next.js frontend with interactive code editor, PostgreSQL for persistent data, and AI API integration for intelligent tutoring responses. Implemented service-repository pattern for clean architecture separation.

Results

Platform provides instant AI-powered tutoring with real-time code evaluation, adaptive learning paths, and comprehensive progress tracking.

Digital Networking Platform

CAPY Card

Cloud Engineering2025

Challenge

Professionals needed a modern, digital-first business card solution that could replace traditional paper cards while maintaining instant sharing capabilities.

Solution

Architected serverless backend using AWS Lambda and API Gateway for scalable, cost-effective API handling. Implemented JWT-based authentication with secure user profiles, and designed relational database schema using SQLAlchemy ORM with Alembic for version-controlled migrations.

Results

Fully serverless platform handling 1000+ daily API requests with automatic scaling, sub-100ms response times, and zero infrastructure maintenance.

Tunable Consistency Replication System

Distributed Key-Value Store

Distributed Systems2026

Challenge

Systems required a distributed data store that could balance consistency and availability based on application needs, while handling network partitions gracefully.

Solution

Implemented tunable consistency using quorum-based replication for strong consistency (CP) and gossip-based synchronization for eventual consistency (AP). Created Docker-based testing environment to simulate various failure scenarios including network partitions, node crashes, and latency variations.

Results

Successfully demonstrates both CP and AP modes with configurable consistency levels, handles network partitions without data loss, and maintains throughput under failure conditions.

Dynamic Scaling Simulation

Elastic Auto-Scaling Infrastructure

DevOps2026

Challenge

Cloud applications need to handle variable workloads efficiently without over-provisioning resources or experiencing performance degradation during traffic spikes.

Solution

Developed a dynamic scaling system that monitors response times and automatically adjusts service replica count. Implemented predictive scaling algorithms that analyze historical traffic patterns to provision capacity ahead of demand spikes.

Results

Achieved 40% cost reduction while maintaining 99.9% uptime. Response time variance reduced by 60% during peak loads.

Memory Management System

Multilevel Paging & Caching

Systems Programming2025

Challenge

Operating systems must efficiently manage virtual memory to physical memory mapping while optimizing for both speed and memory utilization.

Solution

Implemented N-ary tree page tables supporting multi-level virtual-to-physical address translation. Created custom Not Frequently Used (NFU) cache replacement algorithm with aging for optimal cache utilization. Optimized performance through bitwise operations for faster calculations.

Results

Achieved 95% TLB hit rate with multi-level paging, NFU cache demonstrated 20% improvement over LRU for typical workloads.

Concurrency Synchronization

Producer-Consumer Buffer

Systems Programming2025

Challenge

Multi-threaded applications require safe data sharing between producers and consumers while preventing race conditions and deadlocks.

Solution

Implemented bounded buffer using POSIX semaphores for synchronization. Designed deadlock-avoidance algorithm using resource ordering and careful acquisition sequencing. Created comprehensive testing suite to verify correctness under various concurrent scenarios.

Results

Zero race conditions across 10,000+ test iterations, deadlock-free operation under maximum throughput conditions.

Nonprofit Web Application

SDSU App Dev Club

Project Management2025

Challenge

A nonprofit organization needed a custom web application to manage member engagement, event scheduling, and resource sharing among 200+ monthly active users.

Solution

Led end-to-end software development lifecycle from requirements gathering to deployment. Established Git workflows with code review standards, implemented CI/CD pipelines for automated testing and deployment, and coordinated feature teams across 15+ developers.

Results

Successfully delivered production application serving 200+ monthly users, reduced deployment time by 70% through CI/CD implementation.
