Last position:
Business Intelligence Consultant (freelance) at NBIC – Nisanthan BI Consulting
Advising companies on building, migrating and optimising BI and reporting landscapes (Power BI, SQL, Python, ETL)
5 client engagements in real estate and finance since 05/2025: taking over and stabilising existing reporting, automating recurring standard and management reports, building cash-flow models
Proposal and feasibility assessments for BI and reporting projects
Using AI-assisted development (Claude Code) to accelerate automation, tooling and web/app development
Custom ERP system
Problem: A client's core processes ran on scattered, siloed Excel files with no central data storage – error-prone, hard to scale and impossible to analyse end-to-end.
Approach: Captured the business processes and requirements, modelled the data and developed iteratively together with the business team.
Implementation: Built a tailored, web-based ERP system with a central database, role-based modules and automated reporting – delivered using AI-assisted development in Claude Code.
Timesheet app
Starting point: Time tracking based on an overgrown, macro-heavy Excel template – maintenance-intensive, single-user and error-prone.
Implementation: Migrated all functionality and VBA macros into a standalone web app with central data storage, multi-user support and automated reporting.
Cash-flow modelling
Starting point: The existing cash-flow model covered standing investments only; project developments were missing from steering.
Implementation: Built and extended the CF model to include project-development cash flows.
Optimisation: Reviewed and optimised existing CF models and expanded the KPI outputs for reporting and steering.

About the technology
What T-SQL does
T-SQL, short for Transact-SQL, is Microsoft’s extension of SQL for working with relational data. It adds variables, control flow, error handling, stored procedures and functions to standard SQL. Companies use it mainly with SQL Server and Azure SQL to build data services, business logic and reporting workflows.
Microsoft data ecosystem
T-SQL specialists usually work across the Microsoft data stack. Their toolkit may include SQL Server Management Studio, Azure Data Studio, SQL Server Agent, SSIS for integration, SSRS for reporting and Power BI for analysis. Knowledge of Windows, Azure, security roles and source control supports reliable delivery.
- Stored procedures, views, functions and triggers
- Query plans, indexing and database performance
- SSIS packages and scheduled data loads
- Reporting datasets and Power BI models
Typical project work
T-SQL appears in new database builds, application back ends, data migrations and operational reporting. Professionals may create schemas, transform large datasets, reconcile records or expose controlled data for applications. They also maintain legacy SQL Server estates while moving selected workloads to Azure SQL.
When companies need specialists
Freelance expertise helps when internal teams face a difficult migration, slow queries, unclear database logic or a reporting deadline. It is also useful for audits, disaster-recovery preparation and the redesign of procedures that have become hard to test or maintain.
- SQL Server version upgrades and Azure SQL transitions
- Query tuning and execution-plan analysis
- Data cleansing, migration and reconciliation
- Secure access models and operational documentation
T-SQL alongside other skills
Strong professionals understand relational modeling, normalization, transactions and concurrency rather than writing isolated queries. They can connect T-SQL work with C#, .NET applications, APIs, Python data workflows or cloud services. Familiarity with PL/SQL helps when systems are compared with Oracle, while standard SQL knowledge supports portability.
What good work looks like
Reliable T-SQL is readable, testable and safe under realistic data volumes. Experienced specialists explain indexing decisions, handle nulls and transaction boundaries carefully, and measure changes with execution plans instead of guesswork. They document dependencies, protect sensitive data and leave clear deployment and rollback steps for the team in Berlin or a remote setting.
Frequently asked questions
Before you brief your next project: the most common questions about T-SQL.
T-SQL is used to query and change data in Microsoft SQL Server and Azure SQL. It also supports stored procedures, functions, triggers, transactions, validation and scheduled database operations.
T-SQL includes standard SQL features but adds Microsoft-specific procedural features such as variables, loops, error handling and built-in functions. This makes it well suited to business logic that runs close to SQL Server data.
T-SQL is the natural choice when the company relies on SQL Server, Azure SQL and Microsoft data tools. PL/SQL fits Oracle environments better, so the existing database estate, integration needs and team skills usually guide the decision.
A strong T-SQL specialist should understand relational data modeling, indexing, transactions and security. Experience with SSIS, SSRS, Power BI, Azure SQL, .NET or migration tooling can be important depending on the project.
The right level depends on the risk and scope of the work. A focused reporting change may need solid query and testing skills, while a migration, performance investigation or high-impact database redesign calls for a professional who can assess dependencies and production behavior.
Yes, T-SQL work is often suitable for remote collaboration when secure access, sample data and clear deployment procedures are available. On-site sessions in Berlin can still help with workshops, legacy-system discovery or close coordination during a critical migration.
Ask a T-SQL professional to explain query plans, indexing choices, transaction handling and test coverage in terms your team can verify. Reviewable scripts, repeatable deployments, documented dependencies and measured performance changes are stronger evidence than a list of tools.
A T-SQL engagement may involve database design, query tuning, data migration, reporting logic or support for a wider Microsoft data environment. Professionals should clarify SQL Server versions, Azure usage, access constraints, delivery standards and whether collaboration is remote or includes meetings in Berlin.
