Custom services and backend development Develop APIs, middleware, and reusable services that transform, validate, enrich, route, and synchronize data. Integrate using XML, JSON, REST, SOAP or Web Services, webhooks, CSV, flat files, and SFTP as required. Build scheduled, event-driven, and near real-time processing with appropriate authentication, retries, and exception handling. Connect external validation and compliance services to workflow decisions, alerts, and alternate paths. Database architecture and data quality Design and optimize relational schemas, staging tables, complex SQL, views, functions, stored procedures, and data transformation processes. Develop mapping, normalization, matching, deduplication, validation, audit logging, and reconciliation processes. Investigate data integrity and performance issues across high-volume transactional systems, reporting databases, and data warehouses. Reliability and support Choose suitable synchronous, asynchronous, queued, or scheduled patterns for each integration; build monitoring and actionable alerts. Diagnose failures across payloads, APIs, databases, logs, and ERP configuration; resolve root causes and document findings.
