Charlotte, NC · Custom Software + AI

Custom software for Charlotte — built the AI-native way.

We pair senior engineers with an AI-accelerated delivery model to ship custom software for Charlotte's banking, fintech, and B2B SaaS operators — without the fragile output that gives AI a bad name.

Senior-only engineering · AI-accelerated delivery · you own 100% of the code

AI changed the economics of custom software. We rebuilt our process around it.

Charlotte is one of the country's largest banking and financial-services markets — anchored by Bank of America, Truist, Wells Fargo's east-coast bench, and a fast-growing fintech and B2B SaaS engineering scene from Uptown out through SouthPark and Ballantyne. Senior hires are six figures, months out, and picked over by financial-services giants and the venture-backed challengers around them. AI changes the math, but only when senior people own the parts AI gets wrong.

On a Charlotte banking, fintech, or insurance build, AI is fast and useful for the repetitive 70% — schemas, scaffolding, CRUD, dashboards. The 30% AI gets confidently wrong is the part your bank examiner or QSA will absolutely catch: cardholder data accidentally landing in logs, idempotency on a wire or ACH handler, SSO claim assumptions on a nested AD group, and integration with mainframe-era systems AI invents instead of reads. Raw AI output ships those silently.

We build for Charlotte operators — fintech and payments platforms scaling toward compliance, retail-banking internal tools, insurance and claims platforms, B2B SaaS shipping into financial-services buyers, and modernization of decades-old enterprise stacks. Our model: AI handles scaffolding and the repetitive 70%; a senior engineer owns architecture, security review, and signs off on every change.

Show, don't tell

AI writes the first draft. A senior engineer signs off.

Every change runs through review for security, tests, and architecture before it ships — that review is the product.

On a Charlotte banking or fintech build, the failure modes are cardholder data in logs, non-idempotent payment handlers, and silent reconciliation drift. Senior review catches them before a QSA or a bank examiner does.

What we build for Charlotte companies.

Fintech

Fintech & payments platforms

Customer-facing apps, ledgers, and risk pipelines for regulated, data-heavy products.

Product

SaaS platforms

Multi-tenant products with auth, billing, and dashboards — MVP to scale.

Insurance

Insurance & claims platforms

Underwriting tools, claims automation, and broker portals for carriers and InsurTechs.

Modernize

Modernization

Move legacy systems onto a modern, maintainable stack — incrementally, no big-bang.

AI

AI applications

Copilots, RAG, search, and agents grounded in your data, with guardrails and evals.

Internal

Internal tools & copilots

Operations tooling that replaces the spreadsheet-and-tribal-knowledge workflow.

Senior, on-shore, AI-accelerated

A senior team that moves at AI speed.

You work with senior engineers in Eastern Time who own architecture, regulated-finance posture, and quality — fitting into an Uptown banking-IT rhythm, a SouthPark fintech standup, or a Ballantyne enterprise PR review — not a junior pool with raw AI output bolted on.

Charlotte's senior engineering pool is concentrated around Bank of America, Truist, and the regional financial-services bench — three-to-six months to hire and quietly poached by coastal remote roles. An AI-native team gets you shipping this week, flexes monthly, and doesn't need an Uptown office lease.

Common questions from Charlotte teams.

Do you work with Charlotte companies?
Yes — we serve Charlotte, Raleigh, Greensboro, and Winston-Salem companies with senior, on-shore engineers in Eastern Time. Most collaboration is remote-first, with on-site available for kickoffs and key milestones.
Do you build for regulated banking (SOC 2, PCI, FFIEC)?
Yes. We architect with the relevant control catalogs in mind from day one — tokenization, isolated data zones, audit trails, supervision logging — and we've shipped into SOC 2-audited and PCI-scoped environments. We don't certify you; we build code that survives your examiner's questions.
Can you integrate with our core banking, mainframe, or COBOL systems?
Yes. We've built modern UIs and APIs on top of mainframe-era systems and COBOL batch jobs — without rewriting them. We map the existing integration contracts (badly documented and full of gotchas) and build adapters AI can't invent — because they're real and AI doesn't know them.
Is AI-built software production-ready?
Yes — when a senior engineer reviews every output, adds tests, and hardens it. The horror stories come from shipping raw AI code unsupervised. We don't, and we support what we ship.
Will we own the code?
100%, from day one. We deliver to a repository you control — no proprietary platform, no lock-in.
How fast can we start?
Usually within days. A short scoping call defines the build, the timeline, and a fixed quote.
Can you work with our existing team?
Yes — we augment in-house teams, review their work, and set standards, or run the build end to end. We flex to how you work.
