Data Infrastructure Engineering for Banking & Insurance
The Oracle renewal notice is usually what starts this conversation. We modernize policy administration, claims, and core banking databases off it without touching the business logic on top, and build the governance controls an audit actually tests.
Where Legacy Banking & Insurance Systems Actually Break
A policy admin or core banking database that's run fine for a decade doesn't fail because the technology aged badly, it fails because the license cost or the audit scope around it changed. An Oracle renewal comes in at a price that no longer makes sense, or a compliance review asks a question about access control nobody's had to answer precisely before.
The instinct is to treat a migration as a full rewrite, and the business logic, rating rules, underwriting, account calculations, gets tangled up with the fear of touching the database underneath it. In practice, the database and the logic on top of it are usually separable, and migrating the former doesn't require rewriting the latter.
Governance has the same shape. Row-level security and encryption that were "good enough" when nobody was checking become the finding that fails an audit, because "anyone with database credentials can query it" is not an answer a regulator accepts.
We scope migration, governance, and database performance to the specific system carrying the license, compliance, or performance risk, not a wholesale platform replacement.
Five Problems We See Repeatedly, and How We Handle Them
Real scenarios, not a checklist of generic capabilities.
An Oracle license renewal notice arrives with a price nobody budgeted for, and migrating off it looks like it means rewriting years of policy or account logic.
We migrate the database underneath policy admin, claims, or core banking systems, leaving the rating, underwriting, or account logic on top largely untouched.
Data ModernizationA compliance audit asks who can query a table with customer PII or PHI, and the honest answer is broader than anyone's comfortable admitting.
We classify sensitive fields, build row-level security and encryption, and map access controls to what an auditor actually tests.
Data Governance & SecurityA core banking or claims database that's run fine for a decade starts timing out as record counts and regulatory reporting volume grow.
We profile the actual query plan and fix the specific bottleneck, without a platform replacement that resets years of stability.
Database EngineeringA migration off a legacy system gets proposed, and everyone's first question is what happens if it goes wrong mid-cutover.
We build dual-write or CDC-based replication so the old and new systems stay in sync during the transition, with a rollback path at every phase.
Real-Time Data EngineeringUnderwriting and claims triage still run on manual judgment, so two adjusters can reach a different risk call on the same file.
We build a risk or credit score with reason codes from your claims and policy data, so review queues rank by actual loss likelihood, not arrival order.
Data AnalyticsFrom a Recent Engagement
A US insurance product platform moved from Oracle to PostgreSQL: 120+ PL/SQL packages converted, 100% data integrity preserved, zero downtime, and a 60%+ reduction in licensing cost.

PostgreSQL and MySQL as migration targets, Kafka for CDC-based replication, Vault for encryption and key management, and Terraform for the infrastructure underneath it.
We work hands-on with: PostgreSQL, MySQL, Kafka, Vault, Terraform.

Market Segments Served
We work with banking and insurance organizations where legacy migration or governance scope is the actual risk.
- Insurers running policy administration or claims on Oracle or another aging platform
- Banks and credit unions modernizing core banking or account databases
- Insurance and banking teams ahead of a state or federal compliance audit
- Companies facing an Oracle license renewal that no longer makes financial sense
- Regulatory reporting teams whose database can't keep up with growing volume
- Insurers and banks that inherited a database nobody currently on staff designed
Delivery Lifecycle
Discovery & Assessment
We review your schema complexity, Oracle-specific logic, and compliance scope before any migration commitment.
Architecture & Design
We design the migration and governance architecture for your specific system, with a phased cutover plan and rollback path.
Build & Integration
We implement dual-write or CDC replication and the governance controls end to end, integrated with the systems your team already runs.
Testing & Validation
We validate against real production data and load, with a tested rollback at every phase before cutover.
Launch & Ongoing Coverage
We execute the cutover, document runbooks, and stay on retainer for incidents and the next compliance cycle.
Why Banking & Insurance Teams Work With Us
Depth Across the Whole Stack, Not Just One Layer
A migration vendor moves the data. A compliance consultant writes the policy. We bring migration, governance, and database performance engineering as one team, so a cutover and an access-control gap don't fall to two different vendors.
A Team, Not One Person's Calendar
A single in-house hire means business hours and one person's availability, with everything waiting when they're out. We bring a team behind every engagement, so a migration cutover doesn't wait on someone's vacation.
Every Migration Ships With a Rollback Path
Dual-write or CDC-based replication keeps the old and new systems in sync during the transition, so a cutover that doesn't go as planned isn't a crisis, it's a rollback.
No Dependency by Design
Runbooks and documentation are part of the deliverable, so your team can run and audit what we built without us in the room. If ongoing coverage is still the right call, we'll say why, not just assume it.
