LLM Application Development for Banking

LLM Application Development for banking, built around the constraint that defines the sector: core banking systems are not to be touched, so everything integrates around them.

What changes when it is banking

An LLM app without an evaluation suite is a system nobody can safely change. We ship the tests alongside the feature, so your team can keep moving after we hand over.

In banking, core banking systems are not to be touched, so everything integrates around them. That single fact reshapes how llm application development has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is AML alert triage, usually integrated against Finacle. We build the smallest thing that proves the case, put it in front of real users, and expand only what earns its keep.

Built by engineers who ship production systems, not by a practice that subcontracts the build. Six weeks to something running in production, not six quarters to a strategy document.

Questions from this sector

Will this touch our core banking system?

No. We integrate through supported interfaces and read replicas, never by modifying the core.

How do you handle AML false positives?

Context enrichment and tuned scoring so alert volume matches investigator capacity, with every decision explainable in a case file.

Which model should we use?

It depends on the task, not on the leaderboard. We benchmark your actual workload across providers and usually end up routing, a strong model for reasoning, a cheaper one for classification and extraction.

How do you control the token cost?

Caching, routing, prompt compression and hard budget ceilings, with per-feature cost monitoring so a runaway loop shows up in hours rather than on the monthly invoice.

Can you work with our existing codebase?

Yes. Most of our LLM work lands inside an existing product rather than as a greenfield app, and we match the conventions already in your repository.

LLM Application Development for banking, worth a conversation?

Tell us the workload and the regulation it sits under. We will tell you what is realistic.
