Technology ASP.NET Core, Dapper, SQL Server, Payment Gateway Webhooks, Redis Caching, RBAC

Outcome Reduced application processing cycles by 65%; automated end-of-day treasury reconciliation with zero ledger discrepancies.

IoT Logistics & Infrastructure

Fleet Telemetry & Remote Cold-Chain Sensor Hub

Solution Engineered cellular IoT gateway units transmitting calibrated temperature, humidity, GPS coordinates, and door sensor status every 30 seconds to a time-series engine.

Technology GPRS / GPS Hardware, MQTT TLS, SignalR Real-Time Hub, RabbitMQ, PostgreSQL

Outcome Instant alerts for thermal threshold breaches enabled proactive route intervention, safeguarding transit cargo integrity.

ERP Manufacturing Enterprise

Multi-Plant Manufacturing ERP & Inventory Core

Challenge Three manufacturing plants operated on siloed spreadsheets, creating procurement blindspots, inventory double-counting, and delayed GST reconciliation.

Solution Built a custom multi-tenant ERP platform supporting plant-level raw material requisition, bill of materials (BOM), automated dispatch, and unified balance sheets.

Technology .NET 9, SQL Server Stored Procedures, Docker, Bootstrap, REST APIs

Outcome Eliminated inventory discrepancies across all plants; slashed month-end financial closing time from 12 days to under 48 hours.

HRMS Large Enterprise Workforce

Multi-Location Face Attendance & Statutory Payroll

Challenge Managing 1,800+ employees across 14 branch offices with manual card punching led to buddy punching, proxy attendance, and tedious payroll calculation.

Solution Implemented biometric and AI face-recognition terminal sync to a central HRMS platform with automated overtime rules, leave deductions, PF/ESI generation.

Technology Biometric API SDK, Python Face Verification, ASP.NET Core, SQL Server

Outcome Completely eradicated buddy punching; monthly payroll processing run automated to complete in under 15 minutes.

Automation Heavy Engineering

Shop-Floor PLC Machine Telemetry & OEE Portal

Challenge Unscheduled machine stoppages caused cascading delays on production lines, with plant managers relying on verbal handover reports at shift ends.

Solution Engineered Modbus-to-Ethernet gateway bridges capturing spindle RPM, cycle duration, energy draw, and error flags directly into an operational dashboard.

Technology Modbus TCP/IP, Industrial Edge Gateways, Node.js, WebSockets, Chart.js

Outcome Live OEE tracking enabled immediate supervisor response upon minor stops, reducing machine idle time by 28%.

Payment Financial Commerce

High-Throughput UPI Dynamic QR & Auto-Reconciliation

Challenge Cashier queues suffered from slow POS terminals, while end-of-day bank settlement reconciliation required manual spreadsheet cross-referencing.

Solution Architected dynamic UPI QR generation directly on terminal displays with sub-second websocket confirmation callbacks and automated bank settlement ingestion.

Technology NPCI UPI Protocols, Webhook Listeners, C# .NET 9, Redis Cache, SQL Server

Outcome Reduced terminal checkout time to under 8 seconds per transaction; daily auto-reconciliation runs with 99.98% automated match rates.

AI Document Processing & Quality

Automated Invoice OCR & Structured Parsing Pipeline

Challenge Accounts payable teams spent hundreds of manual hours typing vendor invoice line-items from scanned PDFs, leading to typing errors and delayed vendor payments.

Solution Developed an intelligent OCR microservice that extracts vendor GSTINs, PO numbers, tax breakdowns, and table line-items directly into the ERP database.

Technology Python, Computer Vision, Tesseract/Custom OCR Pipeline, Docker, REST API

Outcome Slashed invoice entry time by 82%; automated 3-way PO matching with high extraction confidence scoring.

Water & Government Public Health Engineering Department

PHED Water Revenue Management & Android Spot Billing Grid

Challenge Manual paper meter registers across urban and rural sub-divisions caused 40+ day billing backlogs, high unmetered non-revenue water (NRW), calculation errors on telescopic consumption slabs, and uncollected arrears.

Solution Engineered an end-to-end PHED revenue platform featuring an offline-capable Android spot-billing handheld app with Bluetooth ESC/POS thermal printing, telescopic tariff calculation engine, GIS consumer meter mapping, dynamic UPI QR payments, and AMR/AMI meter gateway sync.

Technology Android Kotlin, Jetpack Compose, ASP.NET Core Web API, PostgreSQL / PostGIS, Bluetooth Thermal SDK, Dynamic UPI API

Outcome Enabled instant on-spot bill delivery, eliminated calculation inaccuracies, reduced billing turnaround from 45 days to instantaneous delivery, and delivered division-level GIS revenue recovery analytics.

Transit & Government State Urban Mass Transit Undertaking

Smart AFC & Integrated Transport Management System (ITMS)

Challenge City bus transport undertaking faced significant fare cash leakage on busy routes, zero live bus arrival predictions for commuters, and manual bus depot crew scheduling delays.

Solution Implemented an integrated Smart AFC & ITMS transit ecosystem featuring 4G/GPS rugged Android conductor ETIMs issuing paper QR tickets, NCMC EMV contactless card validation, live GPS vehicle telematics pushing to transit servers, and central bus depot management (BDMS) crew rostering.

Technology Android Rugged ETIMs, NCMC ISO 14443 NFC, GTFS Realtime Engine, GPS Fleet Telematics, ASP.NET Core C#, Cloud AFC Clearing House

Outcome Achieved 100% auditable fare collection across 350+ fleet buses, reduced ticket issue latency to under 1 second, and delivered accurate live bus ETA dissemination to commuter displays.

AI & Government Administrative & Treasury e-Office

AI-Powered Document Management System & e-Office Workflow Core

Challenge Over 2 million physical paper files and unstructured scanned PDFs across administrative branches caused multi-hour file tracking delays, lost physical records, and slow inter-departmental approvals.

Solution Built a secure, on-premise AI-DMS platform utilizing multilingual neural OCR/ICR (English & Indic scripts), automated NER metadata extraction, pgvector high-dimensional embeddings for semantic search, and Class 3 DSC / Aadhaar e-Sign approval workflows.

Technology Python PyTorch OCR Models, pgvector / Semantic Vector Store, ASP.NET Core 9, Docker, Digital Signature Cryptographic CSP

Outcome Slashed file retrieval latency from hours to under 300ms, achieved 99.2% automated document classification accuracy, and transitioned departments to 100% paperless e-Office compliance with tamper-evident audit logs.
