CONTROL PLANE / SYSTEM IDENTITY

Built under constraint.
Designed to survive.

Backend and distributed systems where correctness, failure modes, and runtime behavior matter more than aesthetics.

SYSTEMS / SCOPE
Authentication & Identity
Event-driven pipelines
Distributed workflows
Service orchestration
Failure handling & retries
Data integrity under load
SYSTEM CAPABILITIES
Backend Systems
Java / Spring Boot / Python / FastAPI
Service design, APIs, business workflows, auth.
Distributed Messaging
Kafka / Async Events / Idempotency
Event-driven pipelines, retries, failure isolation.
Frontend Interfaces
TypeScript / Next.js / React
System surfaces, dashboards, controlled UI.
Infrastructure
Docker / Kubernetes / CI/CD
Provisioning, orchestration, deployment safety.
Data & State
PostgreSQL / Supabase / Migrations
Data integrity, lifecycle, access control.
FAILURE MODES
Partial Service Failure
→ Graceful degradation, circuit breakers, retries with backoff.
Event Duplication
→ Idempotent consumers, deduplication keys, replay safety.
Out-of-order Events
→ Versioned payloads, state reconciliation, ordering guarantees.
Database Contention
→ Transaction boundaries, indexing, isolation tuning.
Deployment Regression
→ Rollback paths, health checks, progressive rollout.
External Dependency Failure
→ Timeouts, fallbacks, defensive client design.
EXPERIENCE
Backend Engineer — NiteShift Systems
Feb 2023 – Present
Owned backend modules for distributed products with real production usage.
  • → Authentication and identity services
  • → Event-driven notifications and workflows
  • → Admin and operational dashboards
  • → Schema design and migrations
Backend Engineer — ETTA Solutions
Jun 2023 – Sep 2024
Built and maintained backend systems supporting financial and enterprise workflows.
  • → Payment and wallet system design
  • → Tender management workflows
  • → SaaS server deployment and operations
Fullstack Developer (Part-time) — Ahaz Software Solutions
Feb 2021 – Dec 2022
Early-stage engineering work across frontend, backend, and integrations.
  • → Modernized legacy React codebases
  • → HRMS backend development
  • → Biometric device integrations (Python)
PROJECT
SPECTRUM
A distributed instance orchestration platform for provisioning, managing, and operating SaaS environments safely.
ARCHITECTURE SURFACE
  • → Spring Boot control plane (API, auth, job state)
  • → Kafka for event-driven orchestration
  • → Python worker for infrastructure execution
  • → PostgreSQL as system-of-record
  • → Secure callbacks and idempotent job handling
OWNERSHIP
  • → Designed end-to-end job lifecycle
  • → Defined event contracts and failure paths
  • → Implemented callback verification and retries
  • → Built state transitions and safety checks
WHY THIS IS HARD
The system must remain correct under partial failures, duplicate events, retries, and infrastructure uncertainty without human intervention.
