Professional Experience

AppUnik — Backend Software Engineer

August 2022 – Present

As a key backend engineer at AppUnik, I work with cross-functional teams to design and implement mission-critical systems for enterprise applications. I focus on building resilient services, observability, and automation.

  • Architect robust backend infrastructures built on microservices and modular architecture.
  • Develop secure, well-documented REST APIs and asynchronous service pipelines.
  • Build automation-driven backend processes integrated with AI and third-party tools.
  • Implement cloud deployment strategies using AWS, DigitalOcean & Nginx; manage CI/CD and containerization (Docker).
  • Manage server operations, database optimization, and large-scale data processing; created database migration scripts using Sequelize.

Key Achievements

Major contributions and recognition during tenure
  • Winner of Developer of the Year (2024) for technical excellence and system-wide contributions.
  • Directed and executed a complete Windows Server → Linux migration, improving uptime and performance.
  • Implemented multi-region caching strategies using Redis for high-speed data access.
  • Built a production-grade microservice ecosystem supporting AI-heavy applications (GPT & Stable Diffusion integrations).
  • Helped improve DB efficiency by optimizing slow queries, adding indexes, and redesigning schemas.
