My Achievements in This Project:

• Developed and maintained core backend services for a complex enterprise insurance / healthcare CRM using PHP 8+, Symfony, and Yii.

• Designed and enhanced business logic across member/client management, workflows, contracts, and configurable care processes.

• Refactored legacy Yii components and introduced cleaner Symfony-based solutions following SOLID and maintainable architecture.

• Improved reliability with unit tests, production troubleshooting (New Relic / Linux), and AWS-backed services.

My Role in This Project:

• Senior Backend Engineer — responsible for backend services, business rules, tests, and production stability on a large US SaaS CRM.

Problems I Solved:

• Worked across a mixed Symfony / Yii codebase, modernizing legacy modules without breaking critical healthcare workflows.

• Implemented and clarified contracts / interfaces so complex business rules stayed testable and decoupled.

• Investigated search and data issues on large datasets (including Elasticsearch) and production incidents affecting live CRM operations.

• Used AWS infrastructure and Linux tooling to keep backend services scalable, observable, and maintainable.

Technologies Used: PHP 8+, Symfony, Yii, PHPUnit, Elasticsearch, AWS, MySQL, Linux, New Relic.

Methodology: Agile methodology with Scrum meetings and 2-week sprints.

Duration of the Project: 1-year fixed-term contract (USA, remote), 2025 – 2026.

About Project

Elligint Health is a US healthcare / insurance SaaS company. Its Helios platform is an enterprise CRM and medical-management system for health plans — care management, utilization management, prior authorization, member and provider workflows, quality reporting, and analytics — supporting millions of covered lives. I worked as a Senior Backend Engineer on the core CRM backend that powers these insurance and care-management processes.

My Role & Contributions

I owned backend work on a large-scale insurance CRM: implementing and extending Symfony/Yii services, encoding healthcare and insurance business rules, writing unit tests, applying SOLID and contract-based design, and debugging production issues. I also worked with AWS-hosted services, search/data pipelines, and gradual modernization of legacy code so new features could ship without destabilizing existing workflows.

Key Features and Problem-Solving

01. Healthcare CRM Backend: Built and maintained backend services for member/client records, configurable workflows, assessments, care planning, and insurance-related business processes used by US health plans.

02. Symfony / Yii Architecture: Worked across a dual-framework stack — extending Symfony services while refactoring Yii legacy modules toward cleaner, SOLID-compliant, contract-driven code.

03. Contracts, SOLID & Unit Tests: Introduced and applied interfaces/contracts and PHPUnit coverage around complex rules so changes could be verified safely in a large enterprise codebase.

04. Search, Data & Production Reliability: Optimized Elasticsearch queries, investigated bottlenecks, and used New Relic and Linux tooling to find root causes of production incidents.

05. AWS & Scalable Services: Worked with AWS-backed infrastructure for storage, compute, and high-availability backend services supporting a national-scale insurance SaaS CRM.
