• Work closely with DevOps teams to support CI/CD pipelines, incorporate intelligent automation, and ensure stable, secure deployment environments. 
• Integrate AI-assisted development practices into coding, testing, documentation, code reviews, and defect prevention workflows. 

Banking & Payment Domain 

• Design backend systems supporting banking products and financial transaction processing. 
• Build and maintain services related to payments, card processing, financial operations, and core banking functions. 
• Ensure backend implementations comply with financial industry standards and security requirements. 
• Collaborate with business and product teams to translate banking and financial requirements into technical solutions. 
• Client Collaboration & Delivery 
• Work directly with client stakeholders, architects, and product owners to understand business processes, requirements and define technical solutions. 
• Challenge and clarify requirements with curiosity dig deep into the "why" behind business needs. 
• Participate in architecture discussions and technical workshops with client teams. 
• Communicate technical designs, trade-offs, and solutions clearly to both engineering teams and non-technical stakeholders. 
• Support project delivery by ensuring technical risks are identified and mitigated early.
