Real Projects Built at PK Rain Technologies, Chennai
We are not a slide-deck training institute. Every course at our Anna Nagar West centre is taught by engineers who ship production AI, cyber security and robotics systems for real clients. These are some of them — and our students build alongside us.
An AI tutor for NEET & JEE aspirants, running on our own GPU.
A full exam-preparation platform that generates practice questions, evaluates answers and explains mistakes using locally hosted language models. Students get adaptive mock tests built from previous-year question pipelines instead of static PDFs.
Natural-language reporting on top of a live Tally ledger.
An integration layer that connects Tally accounting data to an AI assistant, so a business owner can ask questions in plain English and get ledger-accurate answers, GST-ready summaries and automated report generation.
FastAPI
Tally XML API
Local LLM
React
Deployed for a retail jewellery franchise operation in Chennai.
Bulk resume parsing with a human-in-the-loop correction desk.
Recruiters upload hundreds of resumes; the system extracts structured candidate data, scores fit against the job requirement, and routes low-confidence extractions to a human review screen instead of silently guessing.
FastAPI
NLP pipelines
PostgreSQL
VPS deployment
In production for an operations & maintenance services company.
Property search that answers questions instead of listing rows.
A property platform with bulk listing import, structured search, and an AI chat layer running on a self-hosted model so that client property data never leaves the server.
One draft, published everywhere, with AI voice-over and video.
A multi-platform publishing engine with scheduling, per-platform formatting, and an AI pipeline that turns a script into narrated short-form video automatically.
A hardware Wi-Fi defence box built on a Raspberry Pi 5.
A dual-band wireless security appliance that monitors an office network for rogue access points, deauthentication attacks and unknown devices joining the LAN. Students build the same unit hands-on, from flashing the board to writing the detection rules.
Raspberry Pi 5
Python
Linux networking
802.11 monitoring
Deployed at a client site and running in production.
Packet-level visibility for backdoor and C2 detection.
An Ethernet traffic capture and analysis tool with rule-based detection for suspicious outbound connections, beaconing patterns and unauthorised remote access — built during a real client investigation.
USB device triage plus office network discovery in one tool.
A forensics workstation tool that pulls artefacts from connected Android and iOS devices over USB, and separately maps every host on an office LAN with open-port and service fingerprinting.
FastAPI
ADB
Network scanning
React
Used for internal forensics and classroom demonstrations.
A two-armed robot you drive from a browser window.
A dual-arm humanoid platform with multi-servo articulation, custom motion sequencing and a browser-based control interface. Students work through servo calibration, inverse motion planning and real-time control.
Arduino
Servo control
Serial protocol
Web UI
Working lab robot used for live robotics training.
A powered hip-assist frame designed and built by students.
A student-led assistive robotics build: high-torque servo actuation at the hip joint, a load-bearing frame, and gait-phase control logic — taken from bill of materials through to a working prototype.
A lightweight CRM that parses incoming enquiry emails, extracts contact details automatically, and tracks each lead through a sales pipeline — the same backend patterns students learn for IoT device data ingestion.
Every PK Rain student works on a live project, not a tutorial copy. Visit our Anna Nagar West centre in Chennai or send us an enquiry — we will walk you through the lab.
