Integration Engineer with 6 years in IT and 2 years hands-on building and maintaining API integrations on an enterprise insurance platform. I specialize in reverse-engineering undocumented systems — entering with no map, forming hypotheses, and turning opaque cross-system behavior into a documented, testable picture. I design data mappings, implement business rules, debug complex cross-system issues, and ship fixes on live production across 25+ carriers and 300+ products. Workato-certified (Technical Developer). Strong foundation in REST/SOAP, JSON/XML, data transformation, and integration patterns — transferable across platforms, and quick to learn new tools in the context of real work.
EXPERIENCE
Integration Engineer · SoftServe — Ensight Insurance PlatformJun 2024 – Present
• Designed and maintained API integrations for 25+ insurance carriers across 300+ life insurance products (IUL, VUL, WL, Term, LTC).
• Reverse-engineered undocumented carrier behavior — mapping request/response rules through differential testing and observation — and distinguished genuine carrier limitations from mapping defects.
• Independently resolved 230+ production tickets: mapping errors, filtering logic, parsing failures, and business-rule violations.
• Led 20+ new product launches through the full integration cycle — from requirements and mapping design to UAT and production deployment.
• Executed 8+ API migrations from legacy WinFlex to direct carrier APIs, improving platform reliability and maintainability.
• Debugged complex issues across UI, data mapping, calculation engines, and carrier backends — tracing failures by reference ID through logs to locate the true source (never arrived / filtered / failed downstream).
• Implemented conditional business logic, state-based filtering, rider-eligibility rules, dynamic UI configuration, and response parsing; abstracted recurring issues into reusable rules and documented architectural lessons for the team.
• Collaborated with 10+ external vendors and carriers to resolve integration blockers and coordinate releases.
Quality Assurance Engineer · SoftServeMar 2020 – May 2024
• Performed functional, regression, and API testing on enterprise billing and fintech platforms.
• 3+ years on GovTransverse — a large-scale, cloud-based billing platform with complex business rules and multi-year release cycles; validated billing calculations, data consistency, and system behavior after enhancements and fixes.
• Analyzed defects and collaborated with engineers and business analysts to drive resolution.
• Short-term QC engagement on Broadway Technology Platform (financial trading) — functional validation and defect identification within tight timelines.
