Hire the Best Firmware Engineers
in Australia

Welcome to my profile. Are you looking for a Microchip developer to bring your great idea alive? Look no further, I will be your right candidate. My business is registered in Australia with ABN 78 935 931 772, ensuring professional and reliable services. Please bear in mind that I only work with Microchip projects, no ARM/ Raspberry pi/ Arduino. My philosophy of work is always to become a master of limited skills rather than to be jack of all trades. That's why i've been really focus in working projects with microchip PIC16/PIC18/PIC24 and PIC32 over the past 10 years. I have many years of experience in developing quality electronic products for numerous industrial, commercial, medical and military applications. My area of strength is in bootloader, circuit protection, serial data communication and real time data processing using Microchip 8/16/32 bits micro-controller. I can assure you that the design and services that I offer will be of highest quality as I emphasize more on quality projects, not quantities. My key strength: --------------------------------- Microcontroller - PIC18, PIC24, PIC32MX, PIC32MZ. All microchip family Communication - RS232/RS485/RS422, DALI, USB, Infrared, Ethernet, WiFi, Bluetooth Protocol - SPI, I2C, UART, Parallel Industrial Automation - Profinet, EtherNet/IP, EGD (Ethernet Global Data), Modbus. Memory Interface - NAND/NOR Flash, EEPROM, MMC/SD, Serial SRAM, SDRAM Experienced in Baremetal, FreeRTOS, State Machine, Preemptive multitasking, Coorperative multitasking, Circular buffer, Bootloader, TCPIP, Embedded Webserver, SSL, Websockets, Cloud reporting, IOT

Got a hardware product that needs an app? I build the mobile app and the firmware that connects it to your device — Bluetooth (BLE), ESP32/Nordic, OTA updates — so it works reliably in your customers' hands, not just on the bench. I'm Sahil, a senior software engineer with 6+ years building hardware-connected apps across automotive, smart lighting, healthcare, and IoT. Most app developers can't touch firmware, and most firmware engineers can't ship a polished app. I do both — so you hire one person, not a team you have to coordinate. 🔧 What I build for you • Mobile apps that talk to your hardware over BLE/Bluetooth (Flutter, native iOS & Android) • Firmware for ESP32, Nordic & Arduino — and the app that controls it • OTA firmware updates (over BLE or Wi-Fi), done safely • Prototype → reliable, shippable product • Rebuilds of no-code / "vibe-coded" MVPs cracking under real users — AI-assisted to ship faster, without cutting corners on your product 🧠 Why founders work with me • I own the app-to-device seam — the part where most hardware projects stall • I design for the field, not the demo: reconnection, range, OTA, iOS/Android quirks • I catch costly architecture mistakes early — no expensive rebuilds later • You work directly with me — no agency markup, no junior pass-through, no account managers • Clear communication — no jargon, no guessing ⚙️ Technical background • Embedded & IoT: ESP32, Nordic, Arduino, Raspberry Pi, BLE, Wi-Fi, OTA • Systems: C/C++, Python, RTOS (Zephyr), TCP/IP • Mobile: Flutter, React Native, Kotlin, Swift • Cloud/Backend: REST APIs, AWS (incl. firmware/OTA delivery) • AI-assisted delivery — used to move faster, never as a substitute for engineering If you've got a real product or a working prototype and you want the app + firmware built right the first time — not just experimented with, let's talk.
