I am doing a small business to monitor locations of geo-trackers which are given to kids by their parents. Trackers can track position, read heart rate, temperature of body and accidents (g-shock sensor). For now I have a fully working POC which is hosted using native AWS ecosystem. POC includes fully working network transmission solution using LoraWAN radio protocol and radio fidelity network covering my city. All radio frames are encapsulated into UDP frames and are pushed through Internet into MQTT broker through edge network server which is hosted in eu-west. Network server gets data, decodes bytes sequences into a decimal values (location, heart rate etc) and stores them in InfluxDB as a timeseries. During POC I am using Grafana to visualize decoded data and put them on a map and add some additional metadata from sensors (heart, temp etc). As a next step of my project I need a full-stack developer who can build a functional back-end which will get data from InfluxDB (potentially replace Influx with a HTTP endpoint which receives data as a POST messages and store them in AWS native DB), approximate data (to remove any extremum values which looks very weird on a map) and provide websocket/REST interface for this data. As a front-end I need a lightweight web application which works with a back-end REST API and with a websocket interface to pull data streams. As a I mentioned I am doing everything using AWS stack and I want back-end to be fully compliant with this ecosystem and use all PaaS features of AWS with Lambda functions as a serverless back-end logic carriers. I definitely do not need any operational part for my project since I am quite short in people resources so serverless is essential. As a further development of my project I see adding a mobile application as a front-end which will work with a back-end REST/websocket. Adding billing functions (service will be provided on a subscription bases), some additional features to send alerts to a personal trackers (they are capable but this is not in a scope of a POC for now). I will gladly find a professional developer who wants to improve his knowledge in this stack and provide his experience to cover this determined scope of a project and be able to commit into this project further with its growth and advancement. Potential start of a project - about 2 months from today - I am still adding some radio fidelity and testing more stable radio network equipment.

Hello, I must say, I am very excited to read about the project. The reason, its contains IoT, its contain IM protocols like MQTT and it contains API + Mobile apps, all what are are experts in, and when we get all of that in 1 place, the projects gets very very exciting. I have loads of questions, but to start with below are my initial questions. 1. Amazon has option of NoSQL database(and I don’t think we should use SQL based) as Dynamo, in the long run it will be costly though. Other option is setting up another database like Cassandra etc, but that might cost you a lot related to development. 2. Do you already have some kind of DB establish for parents, kids, their devices, IDs and much more? 3. I know you prefer server less, but considering there are so many variables, it will be very difficult to setup as well as admin panel. Possible, yes, difficult, yes! 4. Your budget rang is low, can you increase that as well? ~-~-~-~-~-~- About us ~-~-~-~-~-~- I am Zeeshan, and for most part of last 12 years working over C++(Windows and Mac desktop), Node.JS/PHP/Python (Web and API), Swift/ObjC(iOS) and Java/Kotlin(Android). We have worked over 200+ projects in last 3-4 years alone with the help of a small and very trustable team that works under the same roof. We have best reviews of any freelancer here , 5 / 5 for all the reviews. www.freelancer.com/u/Whizpool.html Thanks, Zeeshan
