An API layer that let a 22-year-old core banking system ship monthly

The challenge

Every digital feature required a change to a mainframe-era core with a six-month release cycle. The bank's mobile roadmap was effectively hostage to a system nobody was willing to modify.

What we built

We built an API and event layer in front of the core: read models served from a CQRS projection, writes routed through an idempotent command gateway with compensating transactions, and change-data-capture keeping projections current within seconds.

Architecture summary

CQRS with event-sourced projections · Kafka change-data-capture from the core · API gateway with OAuth 2.0 and mutual TLS · Kubernetes on a hardened private landing zone · full audit trail on every command.

  • Java 21
  • Spring Boot
  • Kafka
  • Debezium
  • PostgreSQL
  • Kong
  • Kubernetes
  • Terraform

Business impact: Digital feature releases moved from twice a year to fortnightly without a single change to the core system. The core release cycle became irrelevant to the product roadmap.

Clinical document AI that gave 340 clinicians their evenings back

The challenge

Clinicians were spending an average of 96 minutes per shift on documentation and coding. Two previous vendor pilots had failed on accuracy against real, messy clinical notes.

What we built

A retrieval-grounded documentation assistant trained on the network's own templates and coding standards, with confidence thresholds routing uncertain cases to human review and a clinician sign-off step on every output.

Architecture summary

Claude on a private endpoint inside the hospital's cloud boundary · semantic chunking over clinical templates · hybrid search with clinical-terminology re-ranking · full PHI access audit · human-in-the-loop approval gate.

  • Python
  • Claude API
  • pgvector
  • FastAPI
  • HL7 FHIR
  • Azure
  • Databricks
  • Keycloak

Business impact: Documentation time fell by 41% with coding accuracy above the pre-existing human baseline. No PHI left the hospital's cloud tenancy at any point.

A composable replatform that turned peak week from a risk into a record

The challenge

Checkout failures during the previous festive peak cost an estimated ₹4.2 crore in abandoned baskets. The monolithic platform could not scale checkout independently of catalogue browsing.

What we built

A composable rebuild: headless storefront on the edge, checkout extracted as an independently scalable service, real-time inventory orchestration across stores and warehouses, and graceful degradation that sheds non-essential features under load instead of failing.

Architecture summary

Headless commerce with edge-rendered storefront · checkout as an isolated autoscaling service · event-driven inventory orchestration · Redis-backed cart with write-behind persistence · load-shedding by feature priority.

  • Next.js
  • Node.js
  • Kafka
  • Redis
  • PostgreSQL
  • Cloudflare
  • AWS EKS
  • Datadog

Business impact: Peak week ran at 8.4× normal traffic with zero checkout failures and a materially better conversion rate than the previous platform's ordinary trading days.

Straight-through processing for 68% of motor claims

The challenge

Motor claims averaged 11 days to settle, with most of that time spent on manual document handling. Adjuster capacity, not claim complexity, was the binding constraint.

What we built

An intelligent document pipeline handling first notification, estimates and supporting evidence, feeding an externalised rules engine that settles low-complexity claims automatically and routes the rest to adjusters with everything already extracted and validated.

Architecture summary

Document ingestion with classification and extraction · confidence-thresholded human review queue · Camunda decision engine owned by the business · event-driven claim state machine · full decision audit for regulator review.

  • Python
  • Azure AI Document Intelligence
  • Camunda
  • .NET 8
  • SQL Server
  • Azure Service Bus
  • Power BI

Business impact: Settlement time fell from 11 days to 4.9 days overall, with 68% of motor claims settling without adjuster touch. Adjusters were redeployed to complex and disputed claims.

Predicting line stoppages 40 hours before they happen

The challenge

Unplanned downtime across four plants was costing roughly ₹2.8 crore a year. Machine telemetry existed but never left the shop floor, and maintenance ran on a fixed calendar regardless of actual condition.

What we built

Edge collectors with store-and-forward buffering feeding a central lakehouse, anomaly and remaining-useful-life models per equipment class, and predictions surfaced directly in the maintenance planning system as schedulable work orders.

Architecture summary

Edge gateways with local buffering for connectivity loss · MQTT to cloud ingestion · Delta Lake time-series store · per-asset-class RUL models with drift monitoring · bidirectional CMMS integration.

  • Python
  • MQTT
  • Databricks
  • Delta Lake
  • MLflow
  • Azure IoT Hub
  • Grafana
  • SAP PM

Business impact: Unplanned downtime fell 31% across the four plants in the first full year, with overall equipment effectiveness up 18 points on the worst-performing line.

One tracking view across 47 carriers and four transport modes

The challenge

Customers called for shipment status because no single system knew where anything was. Every new carrier took roughly six weeks of bespoke integration work.

What we built

A canonical shipment event model with carrier adapters conforming to one internal contract, predictive ETA models trained on historical lane performance, and proactive exception alerts issued before a customer notices a delay.

Architecture summary

Canonical event schema with per-carrier adapters · Kafka event backbone with replay · ETA models per lane and mode · customer portal with webhook subscriptions · dead-letter queues with automated replay tooling.

  • Go
  • Kafka
  • PostgreSQL
  • Python
  • React
  • AWS
  • Terraform
  • OpenTelemetry

Business impact: Status enquiry calls dropped by 61% and on-time delivery attainment rose to 92%. New carrier onboarding fell from six weeks to three days.

Re-architecting for enterprise buyers without pausing the roadmap

The challenge

The product was winning mid-market deals and losing every enterprise one. Tenant isolation was enforced in application code, there was no SSO, and no usage metering meant pricing was guesswork.

What we built

Progressive migration to database-enforced row-level tenant isolation, an enterprise readiness layer with SAML SSO and SCIM provisioning, usage metering wired to billing, and a documented path to promote large tenants onto dedicated infrastructure.

Architecture summary

PostgreSQL row-level security per tenant · tenant-aware connection pooling · SAML and SCIM identity layer · event-sourced usage metering into billing · per-tenant feature flags and configuration.

  • NestJS
  • PostgreSQL
  • WorkOS
  • Stripe
  • Temporal
  • Kubernetes
  • Argo CD
  • PostHog

Business impact: The platform closed its first three enterprise contracts within two quarters of launch. Security questionnaires that previously took weeks are now answered from an evidence library.

Quarter-end reporting cut from three weeks to two days

The challenge

Consolidated reporting across eleven custodians, four currencies and a multi-entity trust structure was assembled by hand each quarter, taking three weeks and producing figures nobody could fully trace.

What we built

Automated multi-custodian ingestion with daily reconciliation, an entity and beneficiary model supporting look-through reporting, and a secure portal with per-entity access control and complete audit logging.

Architecture summary

Custodian feed adapters with schema validation · daily automated reconciliation with exception queue · bitemporal position store · entity graph with look-through aggregation · immutable document vault with retention policy.

  • Python
  • PostgreSQL
  • dbt
  • Airflow
  • React
  • AWS
  • HashiCorp Vault
  • Snowflake

Business impact: Consolidated reporting moved to a T+2 cycle with every figure traceable to its custodian source. Manual consolidation effort fell by 80%.

The system you keep postponing is the one costing you most.

Every quarter a critical process stays manual, a platform stays unmodernised or a security gap stays open, the cost compounds quietly. A 30-minute conversation is enough to know whether it is worth acting on now — and we will tell you if it is not.
