• Company Overview:
• Works for Proximus in Brussels. It's a telecom industry project, and here we have over 4,000 databases in 300+ MSSQL virtual and physical machines and 20+ clusters in PostgreSQL, including all the DEV, UAT, and Prod environments. We do have all regular activities for the databases here, like all types of maintenance, patching, Always On configuration for HA, regular DR activity, and day-to-day calls with client issues and problem statements. We have regular Microsoft Connect for their new product releases, as well as in case of any challenges in the system. It could involve multiple vendor calls with HP or Cisco in case of network involvement. As it's a telecom industry project, our shops and network must function without any delay or impact, so we make our system robust and redundant. In Proximus, we have other customer projects as well, such as Mensura, Agora, Engie, Luminous, CSJ, and many more. For them, we do have MSSQL Server support, as well as Postgres database support, as these are our customers' customers. This is a really challenging environment, which I am leading from the strategy point of view, as of all types of implementation. We are now focusing on migrating our on-premises infrastructure to Azure managed instances, as we do have all sorts of services running in our environment, such as SSIS, SSRS, and SSAS. Currently, we are in the assessment phase and will soon be deploying our migration strategies.
• Proximus is one of the leading telecom brands in Belgium, and BICS is also our client for international network provider. Our data centers have been run by Datacenter United for the last few months; however, we were managing our DCs on our own. We are also running a green IT solution for the company, and so reducing the carbon emissions is also one of our key goals, which we need to target monthly, and meeting the KPIs. As we work under SLA, the more automation we can achieve is key, and for that, we have a dedicated automation team. With them, we have regular interaction and discussions based on our prepared documentation from the database side.
• Knowing other teammates are also helping, as I am in MSSQL and Postgres as well, so I have good interaction across the team, i.e., Wintel, network, storage, Linux, and AD.

A career at Sapient was a very highlighting part of my journey, where I gained knowledge from one of the leading market projects under the Unilever Group.

The project has MSSQL database administrative work along with Azure data warehouse implementation, and here I have learned the creation of fact and dimension tables, their partitioning, and managing the column store indexes. It was for a short time, but mostly the MSSQL admin work is like what we do in our day-to-day lives: performance issues, replication issues. I was a single member of the database team, so challenges were high under pressure, and that gives me immense strength to deal with pressure situations and find the solution to get rid of all challenges. Learning was continuous, and still, it is continuous.

• I was working on an in-house project for Accenture, where we manage all the internal applications. I have worked in a PASS/IAAS environment here, where I was managing a team of four members. DBA tasks included installation, upgrade, migration, maintenance, troubleshooting user issues, implementation of Azure databases, audits, and monitoring. It's a full-time engagement, along with the application users sitting behind you, and I must say it is very demanding in nature.

• At Birlasoft, I was working for GE and on the US shift. We had a big team of eight members working 24/7. Working on ServiceNow tickets on a daily basis, let's say backup, restore, access, job failed, import, export, installation, migration, upgrade, and all sorts of changes that we do in the MSSQL field.

While working with Religare, I was part of multiple teams, as it was a small group of technical members where IT support, Dialer Support, DB support needed to be handled by ourselves. This is the place where I started learning MSSQL database, as we had daily access requests, backup requests, restore requests, and, apart from that, LAN issues, as well as desktop or laptop OS installation and LAN cabling as part of the IT team. As we do have DC access these days, as I was a Dialer administrator, I am getting familiar with physical machines and PRI cabling for the dialer servers.

• Under Steria Group I was not working as a technical member rather worked for their backgourd process for the BPO industry. But it added values in my corporate thinking and behavious as it was my startup
