In the project, we mainly pull data from tiktok based on provided data by customer. Mainly different brand share their requirements and the backend system pull data from tiktok. Once the data is in our system, the monitoring dashboard generate analytics on different timeseries queries. I was in-charge to develop the monitoring dashboard backend. The backend was based on Python, Django. The complex queries I wrote, was able to calculate analytic data from 60+ TB data in real time. I used redis and django ORM for complex query. In few places, I used raw sql queries to make it faster. Also used materialized views to have data.

I designed and developed an pentest agent. The agent is mainly responsible to scan user network, backend apis and web application. The agent find out vulnerabilities and send back to SaaS backend as real time report via websocket connection.

The pentest agent I developed is based on Golang and used Nmap, Amass, OpenVASS, OWSAP ZAP as tool.

In an network infrastructure system, I was incharge to design & develop the feature called IPv6 Design. There user can generate subnets from a GUA and ULA. User also can generate GUA subnets based on location. By using the subnets, user can populate new subnets for different network element, such as Point-to-point links, Vlans, Data centers & so on.

Also user can allocate new generated subnets to their existing device interfaces. The backend is able to generate config commands with which user can assign subnets.
