## Manufacturing & Garment ERP (deepest domain expertise)

8+ years of hands-on experience across the complete manufacturing lifecycle, built and operated in live factories — not researched.

- [Manufacturing ERP](https://sakinfotech.com/industries/manufacturing/): End-to-end factory systems covering order receiving, merchandising, cost sheet and post-costing, material requirement (MRL/BOM), purchase orders, warehouse control with goods inward notes (GIN), goods received notes (GRN) and goods dispatch notes (GDN), cutting, issue to batch, stitching, in-line QC, finishing, final QC, inspection audit, packing, dispatch and shipment. Includes live TNA (time and action) tracking per task, delivery challan, invoice and packing list generation, one-click e-way bill generation via direct API integration (no portal login or re-keying), live dashboards, and support for multiple factories, warehouses, branches and locations.
- [Garment & Apparel ERP](https://sakinfotech.com/industries/garment-apparel/): Specialist ERP for leather garments, woven garments and leather accessories. Area-based (square foot / square decimetre) leather purchase, costing, issue and consumption with grade-wise rates; shade, lot, roll and hide traceability from inward through bundle to finished garment; size-ratio-aware cutting, output and packing so shortfalls surface at cutting rather than at carton close; job-work and subcontracting tracked as issue and receipt so outsourced WIP stays visible; export documentation generated from one dispatch record.

## Infrastructure & Platform Engineering

- Monolith-to-microservices migration using the strangler pattern behind a Kong API gateway, moving one endpoint at a time with percentage traffic shifting and instant rollback.
- Zero-downtime deployment: Docker containerisation, Kubernetes rolling updates gated by readiness probes, backward-compatible migrations, rollback in seconds.
- Asynchronous architecture with RabbitMQ and Celery so slow third-party APIs (e-way bill, GST, payment gateways) never block a user request; retries with backoff and monitored dead-letter queues.
- API gateway (Kong): centralised authentication, per-consumer rate limiting and quotas, routing, response caching and request logging.
- Quality gates: SonarQube static analysis, dependency scanning and automated end-to-end testing in CI/CD pipelines.
- SaaS and multi-tenant platform engineering, including row-level security for tenant isolation.
- AI-assisted delivery: current AI tooling (Claude, ChatGPT, Gemini) used for scaffolding, test generation, refactoring and documentation to reduce cost on mechanical work. Architecture, security decisions and anything touching money or personal data are engineered and reviewed by a person, and all code passes the same review, static analysis and test gates regardless of origin.
