Backend Architecture & Planning

• Lead backend system design and architecture.
• Produce ADRs, ER/dataflow diagrams, and integration contracts.
• Define non-functional requirements (performance, scalability, security, compliance).
• Establish caching strategies, service decomposition, and API gateway standards.

Backend Development (Laravel & .NET Core)

• Build enterprise-grade APIs and services with Laravel and .NET Core.
• Implement ORM frameworks (Eloquent, EF Core), queues, jobs, events, and background services.
• Optimize performance with profiling, async/await, and caching (Redis).
• Integrate systems such as payments, identity, Survey & Geology System, and reporting.

Data & Database Engineering

• Design and optimize schemas in PostgreSQL, SQL Server, and MySQL.
• Implement replication, backup/restore, and HA/DR strategies.
• Apply query tuning, indexing, and partitioning for high-volume datasets.
• Ensure compliance with MoMP’s data governance policies.

Frontend Collaboration

• Support React-based frontend systems by delivering secure and well-documented APIs.
• Optimize backend responses for multilingual/RTL (Dari, Pashto, English).
• Collaborate with UI/UX teams in API-first workflows.

DevOps & Operations

• Develop backend-focused CI/CD pipelines and deployment automation.
• Containerize services and configure runtime environments.
• Implement observability: logging, metrics, tracing, and runbooks.

Security & Compliance

• Apply OWASP Top 10 principles for backend services.
• Implement RBAC/ABAC, encryption (AES-256, TLS), MFA/SSO.
• Conduct backend-focused audits (SAST/DAST, dependency scanning).

Leadership & Collaboration

• Mentor backend and database engineers.
• Collaborate with frontend engineers to ensure integration quality.
• Provide technical advice for backend-related procurement and vendor evaluation.

Key Deliverables

• Backend Architecture Pack (ADRs, ER diagrams, integration specs).
• Enterprise API Suite (REST/GraphQL, Swagger/OpenAPI, Postman collections).
• Database Artifacts (schemas, migrations, benchmarks, scripts).
• Stable Frontend Integration (API-first, usability tested).
• Security & QA Reports (penetration testing, SCA/SAST).
• Knowledge Transfer Workshops for MIS engineers.

Performance Indicators (KPIs)

• ≥ 90% backend sprint deliverables completed on time.
• API latency (p95) ≤ 400 ms; uptime ≥ 99.5%.
• Database query performance improved ≥ 30% over baseline.
• Zero unresolved high/critical vulnerabilities beyond SLA.
• ≥ 90% automated test coverage for critical backend services.
