Designed and maintained modular microservices, ensuring high throughput and low latency for real-time investment transactions. Implemented horizontal scaling strategies on GKE to handle spikes in user activity.

Integrated secure payment gateways and e-wallet solutions to facilitate cross-border transactions. Ensured compliance with financial regulations (KYC/AML), including seamless identity verification.

Developed APIs to manage user portfolios (US Stocks, Real Estate, and Fixed Income) with real-time valuation updates. Implemented advanced caching using Redis to optimize data retrieval and maintain system responsiveness.

Employed message brokers (e.g., RabbitMQ or Kafka) for asynchronous event processing and reliable transaction logging. Built robust failover mechanisms and fault tolerance to minimize downtime.

Implemented JWT-based role management (admin, investor, partner) and two-factor authentication for secure access. Established rigorous access control policies to protect sensitive user data and transactions.

Set up GitHub Actions pipelines for automated testing, building, and deployment to GKE. Monitored system health with tools like New Relic or Datadog, enabling proactive issue resolution.

Optimized MySQL queries and indexing strategies to handle large volumes of financial data. Conducted load testing and performance tuning to ensure the platform remains stable under high user traffic.

Collaborated with cross-functional teams—product, design, mobile—to align backend services with user requirements. Mentored junior engineers, providing code reviews, design feedback, and guidance on best practices.
