πŸ“Œ Production Projects & Engineering Experience

PrintBridge - Cloud-Native Printing System (PaaS)

printbridge-by-vps.onrender.com | GitHub | May 2026 Backend Engineer | 4-Member Team | Node.js, Express, Sharp, PDFKit, ThingSpeak

  • Accelerated end-to-end remote print execution to under 30 seconds by engineering a Cloud-to-Edge PaaS architecture that bridges a Node.js/Express backend with a local edge daemon for real-time, automated job queuing.
  • Engineered a highly resilient hardware concurrency system by developing a fault-tolerant edge agent featuring multi-OS printer driver fallbacks, mutex locks to prevent physical race conditions, and exponential backoff algorithms.
  • Eliminated server OOM crashes and secured seamless ease of scaling by building a memory-efficient, stream-based document rendering pipeline, while ensuring high availability via real-time ThingSpeak telemetry and a zero-retention file lifecycle.

Digital Democracy - AI-Powered Civic Engagement Platform

Live App | Sep. 2025 - Dec. 2025 Backend Engineer | 4-Member Team | MERN Stack, Gemini AI, Docker, Jest

  • Accelerated admin analytics by offloading heavy data crunching from the single-threaded Node.js event loop to native MongoDB Aggregation pipelines, drastically reducing server memory overhead and network payload.
  • Engineered a 48-hour rolling time-decay trending algorithm and infinite-depth threading by leveraging weighted interaction scores and an Adjacency List pattern, overcoming fundamental NoSQL document size constraints.
  • Developed a robust Admin Moderation and Trust Engine with granular Role-Based Access Control (RBAC) and programmatic policy constraints, empowering moderators with bulk-resolution capabilities to enforce platform safety.

VSKript - Full-Stack Blogging Platform

vskript.netlify.app | Dec. 2025 - Mar. 2026 Full-Stack Developer | 3-Member Team | React, Redux, Node.js, MongoDB, JWT

  • Optimized API response latency by 40% and accelerated database reads, achieving a zero-disk-footprint media upload pipeline by coupling selective data population with on-the-fly cloud stream compression.
  • Built a custom GitHub-style activity heatmap as a reusable React component and integrated Cloudinary CDN for optimized media delivery, improving user engagement analytics and content load times.
  • Engineered a race-condition-proof, privacy-first analytics engine by utilizing cryptographic visitor hashing, atomic database transactions, and MongoDB connection pooling to guarantee data integrity and system stability during heavy concurrent traffic spikes.

πŸš€ Additional Projects

Above Influence Workflow

Above Influence - AI-Powered Wellness & Analytics Tool | GitHub Full-Stack & AI Engineer | 3-Member Team | React, Vercel, n8n, Gemini AI

  • Engineered a LangChain-powered AI orchestration engine with a 3-tier fallback pipeline, optimizing LLM token utilization by filtering raw API datasets into top-tier behavioral signals to compute 0-100% Goal Alignment Scores and automated risk ratings.


Streak Card Dashboard

Streak Card 23 - Dynamic SVG Generator | GitHub Backend Developer | Node.js, Express, SVG, REST APIs

  • Generated 2,000+ dynamic developer widgets by architecting a high-performance Node.js microservice, aggregating cross-platform time-series metrics into on-the-fly SVG renders while leveraging strategic HTTP caching to bypass downstream API rate limits.
