  • Lead Kubernetes Release Engineering initiatives: design, maintain, and optimize containerized workloads using Docker, Helm charts, and K8s manifests.
  • Manage advanced cluster orchestration strategies, ensuring flawless Canary, Blue-Green, or Rolling updates inside Kubernetes with zero downtime.
  • Enforce strict Code Management and Version Control best practices (Git), establishing branching protocols, mandatory PR reviews, and complex merge conflict resolutions.
  • 2. System Optimization & Performance Tuning
  • Conduct deep-dive performance tuning of PostgreSQL (v18/17) databases, optimizing highly complex queries, execution plans, indexes, and views to sustain millions of transactions.
  • Audit and optimize backend .NET (v10/9) microservices and frontend React.js (v19/18) applications to eliminate memory leaks, minimize latency, and reduce compute footprints.
  • Identify structural bottlenecks in high-pressure environments and implement code-level refactoring for maximum throughput.
  • 3. Advanced Bug Fixing, Support & Maintenance
  • Act as the primary technical anchor for tier-3 application support, rapidly isolating, debugging, and resolving complex production issues across multiple modules.
  • Manage, write, and execute robust scripts to ensure exact data synchronization across distributed modules built on a microservices architecture.

  • Kubernetes & DevOps: Deep hands-on experience with Kubernetes (pod lifecycle, services, configmaps, ingress, Helm) and AWS Cloud services (EKS, EC2, RDS, Lambda, S3).
  • Debugging & Code Tracing: Elite ability to reverse-engineer issues, trace errors across distributed microservices, and manage cross-module data synchronization scripts.
  • Version Control: Expert-level knowledge of Git (Gitflow, rebasing, cherry-picking).
  • Soft Skills & Behavioral Traits
  • Resilience Under Pressure: Calm, structural approach when handling production incidents or high-traffic transaction loads.
  • Problem Solver: A natural investigator who enjoys finding the "needle in the haystack" within massive datasets and complex codebases.
  • Operational Ownership: A mindset focused on system reliability, continuous automation, and long-term application health.
