“NextGen scaled us from 2 to 7 dedicated engineers in under a quarter. Enterprise-grade capacity, zero agency drag.”
Sound familiar?
- Reconciliation and reporting still depend on manual spreadsheet steps.
- Audit and access-control requirements slow every release.
- Legacy systems hold critical numbers nobody wants to touch.
- Offshore teams struggle with the precision financial data demands.

Common questions
Will this turn into a sales pitch?
No. The call is about your project: what needs building, what's stuck, and whether we have the right engineers. If we're not a fit, we'll say so.
What do I get for free?
A project plan, roadmap, cost estimate and ROI estimate within 48 hours of your project call. Your first 5 development hours are free, too. We agree the scope and any paid work with you before proceeding.
Do I need a spec or brief?
No. Tell us the problem in plain words and we'll help shape the scope with you.
Are the engineers really in the U.S.?
Yes. Every engineer lives and works in the United States. No offshore hand-offs, and that's in the contract.

NextGen Coding Company provides senior, US-based T-SQL developers for finance systems built on Microsoft SQL Server. Typical assignments include ledger reconciliation, settlement imports, financial reporting, and stored procedure maintenance on SQL Server 2019 or 2022. The work demands careful decimal precision, explicit transaction boundaries, and repeatable processing so retries do not create duplicate postings or hide differences between source records and ledger balances.
Your engineer works your hours and participates in standups, making it easier to coordinate database changes with close calendars and release approvals. We're comfortable working inside a client's SOC 2 security controls. Every engineer lives and works in the US, without offshore subcontracting, and an NDA plus full IP assignment is signed before anyone touches your code.
Frequently asked questions
- What T-SQL skills matter for financial reconciliation systems?
- Look for experience with DECIMAL precision and scale, window functions, transaction isolation, and idempotent stored procedures. Reconciliation also requires handling missing transactions, reversals, duplicate imports, and settlement dates that differ from posting dates. A useful interview exercise asks candidates to explain exception handling and prove that totals remain consistent after retries.
- How can we improve slow SQL Server month-end reports?
- Use Query Store and actual execution plans to distinguish blocking, poor cardinality estimates, parameter sensitivity, and expensive scans. SQL Server 2022's Parameter Sensitive Plan optimization may help eligible queries, but indexing and query structure still matter. Test changes against representative close-period volumes and verify financial totals before promoting a release.
- Can T-SQL prevent duplicate financial postings during retries?
- T-SQL can enforce duplicate protection through unique constraints, stable business keys, and carefully scoped transactions. An import procedure should distinguish a safe replay from conflicting source data rather than silently discard differences. Test concurrent submissions, partial failures, and rollback behavior; application retry logic must agree with the database's transaction contract.
- How would a T-SQL developer work within our SOC 2 controls?
- We're comfortable operating within your existing SOC 2 security controls rather than introducing a separate approval process. For database work, define access provisioning, change review, deployment evidence, and production support boundaries upfront. SQL Server permissions and auditing should follow your policies, with representative test data available outside restricted production environments.
- What should we prepare before hiring a finance T-SQL developer?
- Gather your SQL Server version, deployment tooling, reconciliation rules, and examples of troublesome stored procedures without sharing sensitive records. Explain close windows and approval requirements during a 15-minute call. Most teams can interview matched engineers within a week of that first conversation, with technical discussions focused on their actual finance workload.
- Are your developers really based in the US?
- Yes. Every engineer lives and works in the United States. No offshore subcontracting and no hand-offs to another team. That's written into the contract.
- How fast can someone start?
- Most teams interview matched engineers within a week of the first call. Start dates depend on your interview process.
