Head of IT · SQL Server DBA & Datalab Pantheon developer
I run the SQL Server, infrastructure and ERP integrations a multi-site retailer depends on. I measure the work in milliseconds.
Database development & administration
SQL Server is home ground. I design, tune and run production databases end to end: high availability that holds, backups that actually restore, execution plans read line by line and indexes placed with intent. When something is slow, I answer with wait stats and milliseconds, not guesses.
ERP development & administration
Certified Pantheon administrator and ARES Pascal developer. I make the ERP talk to the real world: every register across every site stays in sync, warehouse scales print exactly what the database says, and payment terminals settle cleanly at checkout.
A three-node virtualization cluster, SAN storage, Windows Server, firewalls and site-to-site VPNs linking six-plus locations. Designed, hardened and run single-handedly.

Dashboards and reports people actually open, in Power BI, Jaspersoft and heavily automated Excel. If a number matters to the business, it shows up on time, every time.
Power BI, Jaspersoft, ETL pipelines
Custom middleware, device and payment protocols, and SQL Server Agent automation: the connective tissue between systems that were never designed to talk to each other.

1,833 ms to 19 ms
Production storage was choking under write load. I traced the stalls through the virtualization stack down to the disk format itself, then rebuilt the storage layout live, with the business running on top of it.
40 s to 4-5 s
Stock calculation was the slowest thing in the company, and everyone had learned to live with it. I redesigned it from the ground up around indexed views, and the wait disappeared.
0 deadlocks
Parallel warehouse scanners kept deadlocking each other mid-transaction. Instead of retry band-aids, I rewrote the locking patterns at the root, so collisions became impossible, not just rare.
66 GB, 0 downtime
Nine core tables and their indexes reorganised onto an entirely new storage architecture while sales kept flowing. Nobody noticed a thing, which was exactly the point.

Penny Plus d.o.o., Sarajevo
The entire IT operation of a multi-site retail company runs through one pair of hands: mine. A virtualized cluster, SAN storage, SQL Server 2022, networks linking six-plus locations, POS endpoints and warehouse management. From database internals to firewall rules, if it has a connection string or a cable, I own it.
2023
Xylon Corporation, Aptha Corp
Short, focused engagements with a single brief: make the data behave. Query optimisation, data modelling and report automation.
2020 - 2023
ASA Osiguranje d.d., Sarajevo
Built the reporting backbone of an insurance company: complex T-SQL and PL/SQL feeding actuarial and regulatory reporting, executive dashboards in Power BI, and ETL pipelines that kept the data warehouse honest.
