Work I'm proud of
Real products solving real problems — from client work to personal builds.
Betorra Gaming Platform
Production backend for a multi-provider gaming platform — architected services supporting 1,200+ games with real-time session management, multi-provider wallet operations, and idempotent transaction processing.
The Challenge
A gaming platform needed a unified backend to integrate multiple external gaming providers, each with different APIs, while maintaining transaction consistency and real-time session management at scale.
The Solution
Built a modular monolith backend with NestJS supporting 1,200+ games across 4 certified providers. Implemented idempotent transaction handling, secure callback validation, and reconciliation pipelines.

Linux Server Monitor
AIOps Dashboard
AI-powered Linux server monitoring dashboard with real-time metrics, anomaly detection, Telegram alerts, and Google AI-driven insights — deployed live on Railway.
The Challenge
Server admins need to manually check system health metrics and often miss anomalies until they cause outages, with no intelligent early warning system.
ChillSpace
Full-Stack Rental Marketplace
Full-stack Airbnb-style rental platform with real-time booking workflows, JWT authentication, third-party payment gateway integration, and clean RESTful API contracts.
The Challenge
Property owners needed a simple, reliable platform to list rentals and manage bookings without the complexity and high fees of major platforms.
VoiceDesk
Local Voice AI Assistant
Lightweight Python voice assistant pipeline using Groq Whisper for ASR, Llama 3.3 70B for response generation, and gTTS for speech output — with custom conversation memory.
The Challenge
Existing voice assistants rely on expensive cloud APIs and lack privacy. Users needed a local-first solution that works without paid subscriptions.
Retail ERP System
Enterprise Web Application
Modular ERP system with 3-tier architecture, role-based access control, and SQL Server backend. Built for retail inventory and billing management.

About
A bit about me
I'm Harsh — a software engineer based in Ahmedabad, India. I work across the full stack, from designing database schemas and APIs to building the interfaces that users interact with.
My most significant work has been at Betorra, where I architected a multi-provider gaming platform — integrating 1,200+ games across 4 external providers, building idempotent transaction processing, and shipping the full API layer running on AWS.
Outside of work, I build things for myself: AI-powered monitoring dashboards, SaaS tools, and automation systems. I'm comfortable picking up whatever stack the problem calls for — whether that's NestJS, Python, React, or something new.
What drives me is turning a complex requirement into something clean and reliable. If you need someone who can own a feature end to end — backend, frontend, and deployment —let's chat.
