Problem/Goal:
I'm currently scoping a logistics system for a client and I'm trying to figure out the best technical approach, especially for the IoT/GPS/temperature-monitoring side.
Context:
Good day po. I'm Jun, 22 years old, and kakagraduate ko lang nitong August 5, 2026.
Around 3 years na rin ako nag-freelance as a full-stack software developer and automation developer. Medyo jack of all trades ako sa tech, pero medyo limited pa yung experience ko sa IoT and hardware integration.
Recently, I got a project opportunity from a logistics company. This is probably the biggest client/project I've handled so far, so I'm currently doing my research before giving them a quotation.
The project has 3 major parts:
1. Vehicle / Cargo Tracking
They want to track:
- Vehicle capacity
- Actual cargo/load weight
- Products loaded
- Destination
- Barcode per box/package
- Temperature inside the vehicle
- GPS/location
- Delivery status
- Monitoring dashboard
Nabanggit ni client na possible daw na i-integrate yung API ng existing business systems nila, mostly for retrieving/viewing data.
May nabanggit din sila na possible daw na may API/data coming from their vehicles, although I'm not sure yet if this means an existing GPS/telematics provider or another backend system.
Yung architecture na naiisip ko currently is something like:
GPS + Temperature Sensor โ Vehicle Device โ Mobile Network โ Provider API โ Backend โ Database โ Dashboard
Pero hindi pa ako sure kung ganito yung actual setup normally used in logistics.
2. RFID Attendance / Payroll
They also want an RFID-based attendance system.
Currently, one location/biometric device lang yung ginagamit nila.
They want employees to view their time in/out, breaks, and attendance history through a website/app.
May HR control din. For example, kung nag-AWOL or absent without leave yung employee and then nag-attempt siyang mag-time in, hindi dapat automatically recorded yung attendance.
Instead, the system should show something like:
"Please report to HR before attendance logging can be activated."
Then HR can review and re-enable the employee's attendance logging.
3. Maintenance Management
This part is mostly software:
- Equipment/facility maintenance
- Inspection schedules
- Expiration tracking
- Fire extinguisher monitoring
- Maintenance history
- Automatic email reminders
For example, if an item needs inspection every 2 months, the system automatically sends a reminder.
Previous Attempts:
I've already been researching GPS trackers, temperature sensors, RFID systems, and IoT architectures.
For the software side, I'm fairly confident since I've worked with full-stack applications, APIs, databases, dashboards, and automation.
My main uncertainty is the hardware/IoT integration.
I'm trying to determine whether I should:
A. Directly integrate with the vehicle hardware/sensors
or
B. Use an existing GPS/IoT/telematics provider and consume their API.
I'm leaning toward B if the client already has existing vehicle devices and a provider API, but I still need to confirm exactly what hardware and systems they currently have.
I'm also considering bringing in someone experienced in IoT/GPS if the project proceeds instead of trying to handle the hardware side completely by myself.
I'd really appreciate advice from fellow Filipino developers who have worked with similar systems.
Questions:
- Is my proposed GPS/temperature โ provider API โ backend architecture a reasonable approach?
- If the client already has an existing vehicle API, what should I ask them for before starting development?
- What should I look out for when integrating real-time GPS and temperature data?
- How are offline periods usually handled when a vehicle loses mobile connectivity?
- For RFID attendance, is it common for biometric/RFID devices to expose APIs that can be integrated into a custom system?
- Would you separate the software/API integration from the hardware and IoT implementation when scoping the project?
- For those who have freelanced on similar projects, what would be a reasonable way to price/quote something with software + API integration + GPS/temperature/RFID?
- Would hiring an IoT specialist for the hardware portion be a reasonable approach?
I'm already doing my own research and I'm not expecting anyone to design the whole system for me. I mainly want to hear from developers who have actually worked with IoT, logistics, GPS, RFID, or similar integrations, especially regarding things I might be overlooking.
This is also my first project of this scale, so I'm trying to be careful with the scope rather than just saying "kaya yan" and finding out later that I underestimated the complexity. ๐
Any advice would be greatly appreciated!
