Sound familiar?
- Billing and provisioning systems are old and brittle.
- Huge data volumes make reports and jobs slow.
- Integrations between OSS/BSS systems keep failing.
- Downtime is expensive and changes feel risky.

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 US-based PL/SQL developers for telecom billing, call detail record processing, and Oracle database work. Typical projects include validating mediated usage records, maintaining rating packages, reconciling roaming charges, and repairing invoice batch failures. In Oracle Database 19c environments, the engineering discussion should address duplicate CDRs, late-arriving usage, partition boundaries, and reruns that must not charge a subscriber twice.
Your engineer works your hours and attends your standups, so database changes can be discussed alongside mediation, billing, and operations teams. All engineers live and work in the US, with no offshore subcontracting. Before code access, we sign an NDA and full IP assignment. Book a 15-minute call with your Oracle version, billing-cycle constraints, and the workload that needs attention.
Frequently asked questions
- What PL/SQL skills matter for telecom billing development?
- Prioritize SQL tuning, bulk processing, transaction design, and experience reasoning about usage events. Ask how a candidate would handle duplicate CDRs, tariff effective dates, and late records after a billing cutoff. Oracle partitioning, DBMS_SCHEDULER, and clear exception logging are useful interview topics, but correct charging behavior should remain the central evaluation criterion.
- How can PL/SQL process CDR files without creating duplicate charges?
- Define a stable event identity and enforce deduplication at the appropriate ingestion or staging boundary. Use explicit processing states, reject tables, and restartable batches rather than relying on file names alone. SQL*Loader or external tables can support ingestion; PL/SQL packages can validate records and coordinate processing. Test replayed files, partial failures, and corrected usage events.
- Why is our Oracle telecom billing batch slowing down?
- Investigate workload growth, execution-plan changes, missing partition pruning, and competing jobs before rewriting packages. DBMS_XPLAN can help inspect how Oracle accesses usage and subscriber tables. Check whether joins multiply records or procedural loops repeatedly fetch tariff data. Evaluate changes against both runtime and billing reconciliation, with particular attention to cycle-end concurrency and recovery behavior.
- How should we manage late usage and backdated tariff changes?
- Keep event time, receipt time, and billing-cycle assignment distinct in the data model. Rating logic should select the applicable tariff version using explicit business rules, not simply the newest row. Test time-zone boundaries, roaming delays, and adjustments to previously billed usage. Agree with billing owners when a record becomes an adjustment instead of entering the current invoice.
- How does a US-based PL/SQL engineer join our telecom team?
- Begin with a 15-minute call about your CDR pipeline, Oracle release, and billing release schedule. Most teams can interview matched engineers within a week of that first conversation. The engineer joins your standups and works your hours. If the match does not work out, we bring in a replacement and provide a proper hand-over.
- 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.
