What we do · Reactit

The software
that finance runs on.

Practice

We build, run and augment the load-bearing software behind a generation of insurers, banks and financial-service institutions worldwide.

01 · Pillars & practices

Our work is structured around three pillars.

We avoid the long catalogue. Three pillars, each staffed by engineers who have shipped it to production at a regulated institution.

Build core systems

We design and build the load-bearing software at the heart of insurers, banks, and financial services — quote engines, policy admin, claims, payments, identity, custom applications.

Core insurance platforms

Life & P&C systems that pass regulator audits, scale to millions of policies, and remain maintainable for a decade.

Policy admin
Quote & bind
Claims engine
Reinsurance
Templates service

Banking & payments

Core-banking modernisation, bancassurance integration, and payments rails — designed around the institution's actual operating tempo.

Payments rails
Bancassurance gateways
Reconciliation

Identity & access

The identity foundation behind millions of accounts. Multi-realm topologies, OTP fallback, fine-grained audit, federation across partners.

Identity foundation
OTP & step-up auth
Federation
SIEM-grade audit

Run in production

Cloud, data and operations work we will be on-call for. Built so the team that ships it is the team that supports it — with runbooks someone actually wrote.

Cloud infrastructure

Production-grade clusters, networking, storage, and edge — sized for the institution, hardened for the regulator, observable for the on-call.

Container platform
Object storage
Network & firewalls
Multi-region readiness

Data engineering

Operational data platforms, replication, change-data-capture pipelines, and a reporting layer that survives the next audit.

Data quality monitoring

DevSecOps & SRE

Pipelines, observability, runbooks, postmortems. The unglamorous discipline that keeps an institution's nights quiet.

Augment with AI

AI agents, automation pipelines and computer-vision systems — used judiciously, instrumented properly, and only where they earn their cost in a regulated environment.

AI-augmented delivery

AI tooling inside our own engineering loop — not a buzzword, a productivity practice instrumented for safety and cost.

Coding agents
Test generation
Doc & spec drafting
Spec-to-code workflows

Workflow automation

Automation engines connecting legacy mainframes to modern services. The connective tissue of every transformation.

Legacy adapters
Bulk ingestion
Event mesh

KYC, AML & compliance

The regulatory work, done properly. Pipelines and processes designed with the BCT, CGA, IRPP and IFRS reviewers in mind.

AML monitoring
Regulatory reporting
Audit trails

02 · How we engage

Three engagement shapes,
one operating principle.

We staff every engagement with the engineers who will eventually operate the system. The handover is the brief, from day one.

01 / 032 — 4 weeks

Discovery sprint

A short, intense engagement to map the current system, define the target architecture, and surface the riskiest unknowns. We leave you with a written reference architecture and a sized programme — yours to keep.

02 / 033 — 12 months

Build engagement

A dedicated team — engineers, platform, identity, data — embedded in your delivery cadence. We ship to production, we instrument it, and we transfer ownership in the open.

03 / 03Continuous

Reactit On Call

For systems we built or systems we adopted: a continuous-operations engagement with SLAs, monthly reviews, and the team that wrote the code on the line when it pages.
