Dear employer, We looking for long term trust-worthy collaboration so your satisfaction is our target. Please refer to my profile,I have 100% complete rate all on time, on budget. I have done several similar project in Java. We have extensive experience in design and implement Java web service and web crawler, design efficient MongoDB collection structure. To optimised backend performance we will perform source code review combine with profiling/instrumentation to identify bottleneck/hotspot and un-optimised code. We also have experience with using various caching, load balance, clustering mechanism to enhance system performance. To verify system performance we also have experience with performance testing tool like Jmeter to measure system performance against defined criteria. With scheduler by cron expression we propose using Quazt scheduler as it is de-facto standard. Other proposal will be made once we discussed problem in more detail. LET'S START NOW! Looking forward for your response. Regards,

We would like to have one initial call to exchange info about the project just to ensure that we are not over quoting or underestimating the effort. We often recommend per hour costing model for such projects.

I'm first going to become very familiar with the existing code that is written and also the subject matter at hand (fuel costs over time for different vehicles and drivers). I'll understand how you're looking to improve the existing code. I have created Java backends for iOS apps before using NoSQL. One application in particular required CRON jobs that parsed web data.
