Audit-grade correctness for financial systems
Our team brings audit-grade accuracy in financial systems. We keep systems-of-record provable through change—reconciliation intact, controls explicit, and delivery predictable.

“We needed a responsive, web-based sales tool on a very tight deadline. BiTE guided us through every step of our project and were completely committed to our success.”

Senior Director Product Marketing
“Our app’s spending system was more complicated than anything a dating app had done before. BiTE was able to make sense of each possible scenario and use BDD to test for every possible outcome. The result was an app that worked beautifully and didn’t drive us crazy in the process.”
Robin Leigh
Director of Communications“We asked BiTE to pick up another vendor’s project. They audited the code and made corrections and improvements fast. They integrated seamlessly with our team as well as worked directly with our most important clients.”

Engineering for Regulated Change
From mobile and web experiences to backend services and governed agentic automation, we engineer deterministic behavior and audit-relevant evidence as a byproduct of how the software is built and released.
Executable Behavior
Financial correctness starts as code. Using Behavior-Driven Development (BDD), we translate business rules into executable scenarios that run continuously in CI. Authorization rules, limits, state transitions, and reconciliation expectations become contracts that the system satisfies, release after release.
The result: reduced ambiguity and provable behavior as the system evolves.
Change-Safe Delivery Controls
Release confidence comes from verification gates built into delivery. Automated checks validate changes against known financial behavior and operational constraints on every merge and release candidate.
The result: predictable releases and sustained delivery velocity under real financial constraints.
Systems-of-Record First Architecture
Content Ledgers and transaction workflows are treated as first-class architecture, not incidental application logic. We define invariants, isolate responsibilities across services, and design explicit recording and exception paths that keep correctness observable.
The result: consistent outcomes across channels—mobile, web, backend services, and partner integrations.
Evidence-Generating Engineering
Evidence emerges naturally when requirements are executable and delivery is gated by verification. Specifications, test runs, and change records link directly to the behaviors that shipped and the controls that enforced them. This creates a durable paper trail tied to production reality, not retroactive documentation.
The result: defensible change history and fast answers when questions arise.
Gated AI
Qualification gates, schema-validated outputs, and scoped tool authority keep agent execution bounded by explicit rules. Multi-stream observability, evidence-backed claims, and configurable confidence thresholds route high-impact decisions through human-in-the-loop approval paths.
The result: AI that increases throughput while keeping reliability, traceability, and governance explicit.
Senior-Led Control
Correctness improves when senior developers engineer the control system early. BiTE embeds senior talent to define executable behavior, implement verification gates, and establish operational guardrails across mobile, frontend, backend, and agentic systems.
The result: accountable delivery and stable financial behavior over time.
Compliance by Design
Explicit behaviors, traceable from requirement to release

Frequently Asked Questions
Financial Services Engineering at BiTE is the engineering of systems in which correctness must remain provable through change. We build and evolve systems-of-record so reconciliation holds, controls remain explicit, and delivery stays predictable as systems scale.
BiTE works on regulated financial systems that manage money movement, balances, authorization, limits, reconciliation, and reporting. This includes payment platforms, ledger systems, risk and compliance tooling, financial operations systems, and integrations with banks, processors, and partners.
Yes. BiTE engineers systems that perform or govern money movement, including authorization, idempotency, reconciliation, rollback, and auditability. BiTE does not store raw card data.
Correctness is enforced as executable behavior. Authorization rules, limits, state transitions, and reconciliation expectations are translated into contracts the system must satisfy continuously. Behavior remains provable release after release, not inferred after the fact.
Change safety comes from delivery controls built into the system. Automated verification gates validate every change against known financial behavior and operational constraints on each merge and release candidate, preventing silent drift.
Systems-of-record are treated as first-class architecture. Ledgers and transaction workflows are isolated from incidental application logic, invariants are made explicit, and exception paths are designed so correctness remains observable under both normal operation and failure.
Transactional correctness is enforced through clear consistency boundaries, explicit write ownership, and append-only audit trails. Critical state transitions are recorded as immutable events, with traceability from request to outcome across web, mobile, backend services, and partner integrations.
AI is delivered with explicit gates and controls. Qualification gates, schema-validated outputs, scoped tool authority, and configurable confidence thresholds keep agent execution bounded. High-impact decisions route through human-in-the-loop approval paths so reliability, traceability, and governance remain explicit.
Yes. BiTE is SOC 2 certified.
BiTE works collaboratively alongside existing teams as a senior extension of the engineering organization. We integrate into established processes, navigate complex technical and organizational environments, and introduce controls incrementally without disruption or blame.
Teams engage BiTE when financial systems must remain provable under growth, regulatory pressure, operational scale, or architectural change. Engagements may involve new platforms, modernization of existing systems, or sustained operation of high-trust financial workflows.
BiTE is not a fit for superficial integrations or exploratory prototypes disconnected from systems-of-record behavior. Our work is suited to financial systems where correctness, traceability, and long-term control are mandatory.
