- Micro-Frontend Architecture: Architected Webpack 5 Module Federation platform spliting ERP, HRMS, and CRM into
independently deployable frontends — zero cross-product deployment dependency.
- Microservice Backend: Designed three independent backend services (ERP, HRMS, CRM) with structured internal
communication, replacing a monolithic architecture.
- Custom SSO Auth Service: Built unified cross-application authentication providing single sign-on across all three products,
eliminating duplicate session handling.
- Multi-Layer RBAC System: Designed permission structure at projectID:module:sub_module:feature:action granularity,
supporting multiple roles per user and user-level permission overrides.
- Ingene — Genomics Backend: Owned full backend for a biotech platform processing DNA extraction, PCR, and gel
electrophoresis data to generate personalised drug class reports. Integrated and debugged ML inference pipeline end-to-end.
- Performance: Reduced API response times to under 1 second via PostgreSQL query tuning and Django ORM optimisation.
- Team Leadership: Led 4 engineers — code reviews, mentoring, and delivery management across concurrent workstreams.
Tech Stack: Python, Django REST Framework, Angular, 5 Module Federation, GCP (App SQL), Docker, Git

- 6+ years of freelance ERP development specialising in end-to-end systems for SMEs across construction and operations
