Data Integration & ETL

Connect Every Data Source Into
One Reliable Pipeline

Financial institutions run on dozens of disconnected systems β€” core banking, payment gateways, CRMs, compliance tools. We build ETL pipelines that unify all of it into a single, trustworthy data layer your teams can actually use.

Use Cases

Where Data Integration Changes Everything

Real business scenarios where fragmented data costs real money β€” and integration fixes it.

🏦

Core Banking Data Consolidation

Merge transaction feeds from multiple core banking systems into a unified ledger view β€” eliminating reconciliation delays that hold up daily settlement.

Banking
πŸ’³

Payment Gateway Aggregation

Combine data from Stripe, Razorpay, and legacy processors into one normalized stream so finance teams see a single truth for all payment flows.

FinTech
πŸ“Š

Regulatory Reporting Pipelines

Build automated ETL flows that pull from 15+ source systems and produce audit-ready regulatory reports β€” cutting preparation from weeks to hours.

Financial Services
πŸ›’

E-commerce Order & Inventory Sync

Sync order data, warehouse inventory, and logistics tracking across platforms so fulfillment teams work from one accurate dataset.

Retail
πŸ₯

Patient Records Unification

Consolidate EHR data from multiple hospital systems into a normalized patient timeline β€” improving care coordination and reducing duplicate tests.

HealthTech
Core Capabilities

What Our ETL Solutions Handle

From batch ingestion to real-time streaming β€” our integration layer adapts to how your data actually moves.

πŸ”„

Batch & Real-Time Ingestion

Support both scheduled batch loads and event-driven streaming pipelines. We design for your actual latency requirements, not a one-size-fits-all pattern.

🧹

Data Cleansing & Normalization

Deduplication, format standardization, and validation rules applied inline β€” so downstream consumers always receive clean, consistent records.

πŸ”Œ

Pre-Built Connector Library

Ready connectors for 80+ common enterprise systems β€” Salesforce, SAP, Oracle, Snowflake, Kafka, REST APIs, SFTP feeds, and legacy flat files.

πŸ“ˆ

Schema Evolution Handling

Automatic detection and adaptation when source schemas change β€” no more broken pipelines at 2 AM because a vendor added a column.

πŸ›‘οΈ

Data Lineage & Audit Trails

Full traceability from source to destination. Know exactly where every record came from, when it was transformed, and what rules were applied.

⚠️

Alerting & Self-Healing

Smart monitoring that detects anomalies, retries failed records, and escalates only when human intervention is genuinely needed.

How It Works

How We Build Your Integration Layer

πŸ”
1

Source Inventory & Mapping

We catalog every data source, document schemas and access patterns, and map the logical relationships between systems.

πŸ—οΈ
2

Pipeline Architecture Design

Choose the right orchestration engine, define transformation logic, and design error-handling flows before writing any pipeline code.

βš™οΈ
3

Build & Transform

Develop extraction connectors, transformation rules, and loading procedures β€” with unit tests on every transformation step.

πŸ§ͺ
4

Validation & Load Testing

Run pipelines against production-volume datasets to verify accuracy, throughput, and recovery behavior under real conditions.

πŸš€
5

Deploy & Monitor

Production deployment with observability dashboards, SLA tracking, and automated alerting β€” plus a 4-week stabilization period with our team on standby.

What Sets Our Integration Work Apart

We have built data pipelines for banks, payment companies, and regulated industries where getting it wrong isn't an option.

βœ“
Finance-Grade Reliability
Idempotent pipelines with exactly-once delivery semantics β€” critical for transaction data where duplicates or missing records mean regulatory trouble.
βœ“
Technology-Agnostic Approach
We work across Airflow, dbt, Fivetran, custom Spark jobs, and cloud-native tools. The tech fits your problem, not the other way around.
βœ“
Handoff That Actually Works
Comprehensive documentation, runbooks, and training for your team. We build pipelines you can operate independently within 90 days.
Why OpenMalo

Why Teams Choose Us for Data Integration

We have seen what breaks at scale β€” and we engineer pipelines that don't.

🏦
FinTech Pipeline Expertise
We understand T+1 settlement, PCI-scoped data flows, and the nuances of financial data where a missing decimal point triggers compliance alarms.
⚑
Performance at Volume
Our pipelines handle billions of records without choking. We tune partitioning, parallelism, and memory management for your specific data shapes.
πŸ”
Security Built Into the Flow
Encryption in transit and at rest, column-level masking, and role-based access controls β€” not afterthoughts, but pipeline design requirements.
πŸ“
Proven Architecture Patterns
Medallion architecture, change data capture, event sourcing β€” we apply the right pattern for your use case, not whatever is trendy.
πŸ§ͺ
Testing as a First-Class Citizen
Data quality checks, schema validation, and integration tests baked into every pipeline β€” not added as a checkbox at the end.
🀝
Collaborative Build Process
Weekly demos, shared pipeline repositories, and transparent progress tracking. You see exactly what we are building and why.

23 Source Systems Unified Into One Analytics Layer

🏦 FinTech

Data Integration for MeridianPay's Analytics Platform

How we consolidated 23 disconnected data sources β€” including legacy mainframe feeds, REST APIs, and SFTP drops β€” into a real-time analytics platform that finance and compliance teams now rely on daily.

The Challenge

A data landscape held together by spreadsheets

MeridianPay's analytics team spent 60% of their time manually pulling data from different systems, reconciling formats, and fixing broken exports. Monthly regulatory reports required 11 business days of manual preparation.

Data scattered across 23 systems with no centralized catalog
Manual CSV exports causing 3-5 day reporting delays
Frequent reconciliation errors in transaction volumes
No data lineage or audit trail for regulatory inquiries

Our Approach: 8-week engagement: source cataloging and schema mapping in weeks 1-2, pipeline architecture and connector development in weeks 3-6, validation testing and production cutover in weeks 7-8 β€” with a 4-week stabilization period post-launch.

FAQ

Frequently Asked Questions

Most projects run 6-10 weeks from kickoff to production. Simple integrations (5-8 sources) can go live in 4 weeks. Complex environments with legacy systems and regulatory requirements typically need 10-12 weeks.
