I build highly scalable, close-to-metal digital systems that directly accelerate business growth. By optimizing runtimes, connection pipelines, and event execution loops, I convert standard business software into high-speed revenue engines.

A full-stack, high-concurrency Learning Management System

• ⚡ Performance Engine: Tuned the NestJS database handler to scale to a peak of 8,884 Requests/Sec with an average response time of 10.75ms (a 6,100% throughput increase).
• ⚙️ Systems Optimization: Eliminated synchronous stdout main-thread query logging to free the V8 event loop and scaled TypeORM PostgreSQL pool allocations to 100 sockets.
• 📱 Native Mobile Client: Developed a modern Flutter app featuring expandable sliver viewports, interactive search focus states with glow animations, and Riverpod state management.
• 🛠️ Tech Stack: NestJS • TypeORM • PostgreSQL • Passport JWT • Razorpay Webhooks • Flutter • Riverpod
• 📂 Source Code: 📱 Frontend Client App | ⚙️ Backend High-Scale Engine

An open-source, high-speed P2P file sharing engine for cross-platform devices

• ⚡ Performance Throughput: Achieves blazing-fast local transfer rates averaging 45MB/s+ over 5GHz Wi-Fi (and 7MB/s over 2.4GHz Wi-Fi) through optimized local socket buffering, dynamic file chunking, and multi-pipe parallel connections to maximize TCP throughput.
• ⚙️ Systems & Networking: Built close-to-metal using advanced systems programming, local socket pooling, custom TCP/UDP socket management, and multi-pipe network discovery.
• 📱 Cross-Platform Ecosystem: Developed natively in Flutter, fully deployed for macOS and Android, with active blueprints rolling out for Linux (Next), Windows, and iOS.
• 🛠️ Tech Stack: Flutter • Dart • TCP/UDP Sockets • P2P Network Discovery • Systems Programming
• 📂 Source Code: 📦 Open-Source Repository

When constructing production platforms, I build around a strict set of software engineering principles to guarantee long-term maintainability, zero-trust security, and maximum performance:

• 🏗️ Decoupled Modular Design: Standardizing on Clean Architecture and Domain-Driven Design (DDD) concepts to enforce strict boundaries between business domains, making updates and scaling frictionless.
• ⚡ Zero Event-Loop Blocking: Auditing V8/Dart runtimes to ensure heavy computational logic is safely offloaded, guaranteeing the main thread remains completely responsive under massive network operations.
• 🔒 Hardened Security Posture: Enforcing secure environment isolation, sanitizing database queries, whitelisting CORS origins, implementing strict Passport JWT lifespans, and stripping all hardcoded secrets from git history.
• 🏊 Connection Pool Optimization: Tuning database handles, TCP window buffers, loopback Unix sockets, and client connections proactively to scale system efficiency under heavy concurrency.
