Building scalable systems, real-time engines & web platforms.
Hi, I'm Vinay Chandola. A software engineer focused on high-throughput backend architectures, spatial database solutions, and production-ready applications. I build systems where performance, telemetry, and reliability are core requirements.
Portfolio
Featured Engineering Projects
Deep-dives into systems I have designed and built. Each project highlights real engineering decisions, metrics, and technical trade-offs.
LogiRoute — Last-Mile Delivery Operations Platform
An enterprise-grade logistics platform managing telemetry scaling, route replication, and spatial geofences. Combines a high-throughput API gateway, an administrative ops dashboard, and a unified mobile client tracking active courier networks.
Spatial Containment
PostGIS polygon check dynamically routing orders inside active Catchment areas.
60fps Path Playback
Ramer-Douglas-Peucker compression reducing telematics payload by 80–90%.
Geofenced Lifecycles
100m geofence restrictions locking driver actions, resolved via server-side Haversine checks.
Automated Payroll Batching
Dynamic pricing rules engine computing base pay, telemetry mileage, night surge & SLA bounds.
PropelDesk — AI-Agent Customer Support & Workflow SaaS
A secure multi-tenant SaaS application that automates customer support tickets. Integrates LangGraph agents to run semantic documentation searches, draft precise email replies, auto-triage issue priority levels, and trigger SLA escalations.
AI Agentic State Machine
LangGraph workflow coordinator matching intent, parsing docs, and responding autonomously.
Multi-Tenant Scoped Guard
Database context middleware isolating customer metrics and preventing cross-tenant access leaks.
BullMQ SLA Escalations
Redis-backed worker tracking ticket timing parameters, triggering immediate dispatcher pings.
Stripe Subscriptions
Complete subscription billing with automated seat licenses, invoice webhooks, and grace periods.
ZenithCart — High-Throughput Headless E-Commerce Engine
A distributed checkout and inventory coordination system. Handles massive load spikes during product flash sales using a highly concurrent Go backend, structured gRPC HTTP/2 services, Redis locks, and RabbitMQ message queues.
Concurrency Lock (Redlock)
Distributed Redis locks preventing double-spend and stock race conditions in active sales.
gRPC Protocol Channels
HTTP/2 binary serialization links, bypassing standard REST bottlenecks and reducing data transfer by 70%.
RabbitMQ Surge Buffer
Queue pipelines absorbing order spikes asynchronously, shielding Postgres from connection timeouts.
Batch SQL Persistence
Optimized Go consumers processing and batch-inserting queued records directly in single transactions.
Polyglot RAG Platform
A split-architecture Retrieval-Augmented Generation (RAG) platform. Combines a Go API gateway handling user JWT auth, routing, and SSE streaming with a Python AI engine orchestrating LangGraph multi-agent pipelines.
- ✓ gRPC server-client protobuf contract
- ✓ HNSW indexing on Postgres pgvector
- ✓ LangGraph agentic document chunking
BreakMyForm
A browser utility for QA engineers designed to autofill web forms with randomized test datasets. Uses semantic DOM selectors to identify input roles and simulates native keystroke triggers to successfully bypass React/Vue virtual DOM states.
- ✓ Manifest V3 background service workers
- ✓ Security fuzzing & normal injection modes
- ✓ Custom keyboard shortcut hotkeys
Multiplayer Ludo & AI Bot
A scalable live multiplayer server hosting a custom-designed smart gaming bot. Achieved stable sub-50ms latency metrics for hundreds of concurrent players via a Redis pub/sub queue infrastructure.
- ✓ Node.js cluster socket synchronizations
- ✓ Redis Pub/Sub room session state broker
- ✓ Intelligent decision trees for game bot
