Senior Java Architect (Freelance)

Project: LMS for Indian Army (Intranet-Based System)

Project Overview

We are developing and stabilizing a mission-critical Learning & Leadership Management System (LMS/LLMS) for the Indian Army, deployed entirely within a restricted intranet environment.

The backend architect will own the complete backend system—architecture, database design, business logic, security, deployment readiness, and production stability.
There will be no higher technical authority above this role.

This is not a feature-development role. This role exists to prevent last-moment failures and ensure a stable, auditable, enterprise-grade system.

Role Summary (Non-Negotiable)

The selected freelancer will act as the Backend Architect & Technical Owner, responsible for:

• Taking full accountability for backend correctness and stability

Core ResponsibilitiesArchitecture & Backend Ownership

• Define API contracts, DTOs, entities, mappers, and versioning strategy
• Own system design decisions and technical trade-offs

Business Logic (LMS-Critical)

• Implement and maintain:
• Multi-level approval workflows (send-back, rejection, re-approval)
• Examination logic (auto question paper generation, randomization, difficulty logic)
• Negative marking and score finalization rules
• Result locking, visibility rules, and audit trails
• Ensure all edge cases are handled and validated

Database & Data Integrity

• Design and optimize MySQL schemas for large datasets
• Handle indexing, joins, reporting queries, and MIS aggregations
• Manage schema changes and migrations safely

Bulk Operations & File Handling

• Implement CSV/Excel bulk uploads with:
• Validation pipelines
• Partial failure handling
• Special character and encoding safety
• Ensure bulk operations do not corrupt data

Security & Audit Compliance

• Implement strict Role-Based Access Control (RBAC)
• Maintain full audit logs (who did what, when)
• Ensure backend logic is compliant with secure, restricted environments

Deployment & Stability

• Deploy and stabilize Spring Boot applications on Linux / intranet servers
• Handle Tomcat/JVM issues, logs, performance tuning
• Support UAT, go-live, and post-deployment bug fixes

Mandatory Technical RequirementsBackend
