Full-Stack IoT Engineer(Remote)

Eindhoven, Netherlands

02/2021 – 02/2022

A Dutch warehouse management company for which I worked remotely, building their package-location tracking and management system from scratch. Ensured each package is equipped with a circuit/sensor to track boxes during shipment using C/C++, NodeJS, Python. Designed multiple prototypes, PCBs and implemented the software on Linux servers. Hardware used includes Raspberry Pis, ESP32, SX1276, GPS, IMUs etc.  After setting up this IoT devices management system, they are now using it in their high-value shipments for testing. Used LoRA wireless mesh technology to ensure smooth communication between the different sensors. Built a web app through which employees can manage devices Their growth in terms of reliability/efficiency of tracking process is expected to increase by 60% leading to more happy customers.

IoT Solution Architect

Lahore, Pakistan

09/2019 – 01/2021

Led a team of 4 to integrate a Contactless Temperature Sensing Device (CTS) with a payroll management system (Finja), i.e. embedded device to measure the temperature of employees using IR sensors (MLX90614 and TOF). Prototyped/designed universal electronic door-locks add-on device DoorNinja with a smartphone app to allow scheduled and managed access to electronic door locks. Delivered 10+ different DoorNinjas to clients across the country. Used ESP32, EPS8266, AVR MCUs. Furthermore, I designed PayNinja to accept digital payments at venues without the internet by exposing a secure WiFi AP to which users can connect and do payment validation/verification over a GPRS connection via EasyTickets (an all-in-one payment app). PayNinja was deployed at 20+ events. Prototyped and designed an add-on (CashlessVend) to allow digital payments from classical vending machines over machine communication protocol MDB.

How do I Work?

Embarking on the IoT development journey, I follow a structured, step-by-step process to ensure success at every stage.

1. Requirements Gathering: The process begins with gathering detailed project requirements, followed by a thorough technical and operational analysis. This helps me understand the specific needs and challenges of the project.

2. Preliminary Research Report: Based on the analysis, I create a comprehensive Preliminary Research Report. This report outlines the technical specifications, potential solutions, and project roadmap, serving as the foundation for the entire project.

3. Prototype Design: Upon approval of the research report, I move into the Prototype Design phase. I use off-the-shelf components, interactive dashboards, and apps to test and validate the prototype’s functionality before moving forward.

4. Development and Deployment: As the prototype takes shape, I transition to full-scale development and deployment. This includes refining the software, integrating the hardware, and testing the solution’s real-world functionality.

5. Final Product Design: With the prototype validated, I craft the Final Product Design, meticulously selecting components for the Bill of Materials (BOM), designing the PCB layout, and developing the enclosure to ensure optimal performance and aesthetics.

6. Production: Once the design is finalized, I work closely with the manufacturer, providing all necessary design files and specifications to bring the vision to life. From prototyping to full production, I ensure every step is seamless and precise.

Throughout each phase, I remain committed to delivering high-quality, scalable IoT solutions that exceeds the expectations.
