• Lead Consultant – Technical Architecture
• IndiGo – Ops Control & Crew Management Systems
• 2023 – Present
• Architecting and evolving real-time operational platforms supporting ~2,500 daily flights and ~60,000 domain events across flight and crew workflows.
• Architectural Evolution
• Led the transition from legacy polling-based updates to a real-time event-driven architecture:
• Replaced scheduled polling with CDC-based change detection
• Optimised IO through Caffeine (in-memory) and Redis caching layers
• Published domain state changes to Kafka
• Aggregated Kafka streams to construct contextual operational views
• Delivered real-time updates to OCC systems via WebSockets
• This transformation reduced operational latency and enabled near real-time flight state visibility across disruptions and IROPS scenarios.
• Distributed Systems & Domain Modelling
• Designed CQRS-aligned service boundaries for flight and crew domains
• Model complex operational constructs including OOOI states, diversions, cancellations, aircraft swaps, and timeline transitions (scheduled → estimated → actual)
• Introduced Camel EIP to standardize integration patterns
• Focused on domain cohesion with architectural flexibility for evolving airline rules
• Strong emphasis on:
• Kafka architecture
• Stream processing
• Event modelling
• Performance tuning
• Distributed state management
• Production Architecture & Observability
• During IROPS-driven production incidents, drove improvements in application-level observability:
• Introduced Prometheus-based contextual metrics
• Strengthened liveness/readiness validation
• Own architectural stability across production environments.
• Architectural Influence
• Collaborate with Principal Architects on system direction
• Provide cross-team architectural guidance to AOCS and Flight Ops platforms
• Define reusable framework foundations and enforce architectural guardrails
• Remain hands-on in core framework design and distributed system challenges.
