I have 15+ years experience of designing, developing and implementing large apps. Concurrent users for these apps is 3000+ per app. Our company is AWS Registered Partner. We can create the software such that it can be installed on cloud (AWS, Azure, Jelastic) or on-premise. The application can be highly available, scalable and secure. We can create CI/CD pipeline with repository (gitlab etc.) and Jenkins. The data can be stored in an appropriate database (cassandra/Hbase or OpenTSDB) for time series data, MySQL/MongoDB for operational data. nginx can be used for webserver and load balancer. We may use Lets Encrypt SSL (free). Graphana/ChartJS etc. to visualise time-series data.
We have mentioned only open source technologies in our tech stack. There are specific technologies in different clouds and we may go with serverless technologies in cloud.
We will guarantee our work and we will request payment only after the work has completed satisfactorily per milestone.
