Data Engineering & Infrastructure Services For FinTech

At MarsDevs, we build secure, scalable, and high-performance data infrastructure that powers intelligent financial products. From real-time transaction pipelines to robust data lakes, our services are designed to ensure your data is accurate, accessible, and analytics-ready. 🔹 Data Ingestion & Integration We set up pipelines to ingest data from banks, credit bureaus, payment gateways, CRMs, and regulatory APIs. We support both batch (ETL/ELT) and streaming (Kafka, Spark, Redis Streams) with connectors for JSON, CSV, XML, PDF, SQL, and NoSQL sources. 🔹 Real-Time Data Infrastructure Build reactive systems for fraud detection, account balance updates, or credit scoring using low-latency stream processing. Our team configures Kafka, Apache Flink, and message queues to handle millions of events securely. 🔹 Data Warehousing & Lakes Design and manage financial data warehouses using BigQuery, Redshift, or Snowflake—optimized for fast analytics, audit readiness, and structured reporting. For unstructured documents (contracts, PDFs), we create searchable document lakes and metadata tagging pipelines. 🔹 Data Modeling & Governance We help you define canonical data models for customers, transactions, accounts, and policies. Our infrastructure includes PII masking, access control, versioning, and data lineage—supporting PIPEDA and GDPR standards. 🔹 Secure API Infrastructure Build internal & external APIs to expose financial insights (e.g., loan eligibility, credit limits) with authentication (OAuth2, JWT), rate limiting, and audit logging. These APIs can power apps, portals, or LLM copilots. 🔹 Monitoring, Logging & Recovery Implement real-time data observability (Prometheus, Grafana), error handling, and backup/restore pipelines to ensure reliability and compliance. ⸻ Whether you’re building a lending platform, a KYC engine, or a real-time transaction monitor, our data engineering team ensures the right data gets to the right model at the right time
