Embedded firmware to cloud platforms — production systems across energy, industry, healthcare, and building technology
Snapshot of active and delivered programs as of May 2026. Capabilities span EV charging, Industry 4.0, AI-assisted healthcare, BMS integration, and enterprise monitoring.
Systems running in the field today — telemetry, OTA, hospital infrastructure, and large-scale industrial IoT.
Production firmware for a Bharat dual-socket EV charger: Arduino C++, MQTT telemetry, OTA updates, and intelligent load balancing across two sockets.
Industry 4.0 program for Ordnance Factory: OEE, vibration, temperature, and oil pressure across five plants — press, furnace, zinc plating, passivation, and pickling.
AI chatbot for doctor directory, symptom analysis, and specialty matching — live with WhatsApp integration and tool-calling architecture on a Go backend.
SNMP-based infrastructure monitoring for Sulaiman Al-Habib Hospital: HP iLO traps, voltage, temperature, and hardware alerting with trap forwarding.
WhatsApp Business API bot for Aditya Laxmi Enterprises, Bhiwandi. Handles customer inquiries, structured intake for document quotations, and order tracking for government and property-related documents in Maharashtra.
BMS platforms, access-control integration, smart-city hardware, and next-generation industrial controllers.
Building management platform: OPC UA auto-discovery, MQTT telemetry, alarm forwarding, and access-control SOAP paths.
Turns BAS/BMS project uploads into structured equipment schedules and BOQ in Excel — multi-format ingestion with SSE progress.
Autonomous solar-powered refuse compression: ESP32 sensing and motor control, deep sleep, UART link to an RP2040 LCD controller.
Direct SOAP integration for Schneider Electric SecurityExpert: door commands, live events, polling, and queued retries.
RP2040 and RK3566 controllers with ladder logic, Modbus RTU/TCP, and BACnet/IP — aimed at a strong cost advantage versus traditional PLCs.
Apartment intercom stack: WebRTC video, Flutter mobile apps, Go signaling backend, cloud dashboard, Raspberry Pi door unit, and in-unit touch displays.
Bridge module integrating Assa Abloy locks with Broadlink RM MAX via local BLE — no cloud dependency. STM32L081 + BL3418-P dual-MCU architecture.
Full-stack order management platform for a Mehndi artistry business. React Native mobile app, vanilla JS web portal, Go Fiber REST API backend.
Field-proven firmware, displays, and connectivity products.
Raspberry Pi multi-unit system: internal, external, and guard stations with SIP calling over LAN or internet.
Ultra-low-power solar light firmware: periodic wake, light sensing, MOSFET LED drive, multi-year battery life.
WiFi smart outlet with power metering, MQTT, and OTA on ESP32-WROOM.
RP2040 driving dual DWin 10.1" displays: daisy-chain UART, configurable targets, production totals.
Dual-core FreeRTOS firmware: peripherals, GPIO/UART/SPI/I2C, low-latency interrupts.
Early exploration, technical documentation, and paused prototypes with lessons learned.
Low-latency Pi intercom: GStreamer H.264 pipelines, V4L2 hardware paths, signaling, TURN, voicemail.
Video door phone with offline BLE 5.0 to Tuya-class locks, AES-128 sessions, local range through doors and walls.
Reference documentation and sample integrations for Tuya Smart SDK on iOS and Android.
Custom ESP32-WROOM board: dual NEMA 23, PWM spindle, BLE, e-stop, and web UI for lappet loom cutting — prototype complete; market sizing paused commercialization.
Wall-plugged gateway device that bridges WiFi to BLE to wake sleeping Tuya smart locks and execute remote commands. Solves the problem of WiFi-disabled sleep locks being unreachable remotely.
