Solution Delivery: Lead the full software development lifecycle, including requirement analysis, technical design, implementation, testing, deployment, production support, and continuous improvement.
Database Management: Develop and optimize database solutions involving large data volumes, complex queries, transactions, database partitioning, and data archiving.
Reusable Components: Design and build reusable Golang libraries, frameworks, and shared components for use across multiple backend services.
File Processing: Develop secure and efficient file-processing solutions, including file streaming, compression, decompression, encryption, and decryption using ZIP and AES.
API Development: Design, develop, and maintain RESTful APIs following OpenAPI standards and secure API design principles.
System Integration: Integrate backend services with Kafka, Redis, PostgreSQL, job-scheduling platforms, and external systems.
Production Support: Investigate and resolve application defects, performance issues, failed batch jobs, and production incidents within strict resolution timelines.
Team Collaboration: Work closely with developers, DevOps engineers, QA teams, business analysts, and other stakeholders to ensure alignment with technical and delivery objectives.
Code Quality & Best Practices: Promote clean code, effective code reviews, automated testing, secure development practices, coding standards, and engineering best practices.
