Roles

Overview

Backend Java engineer at a Middle level specializing in Spring Boot REST APIs with practical role-based security. The strongest proven skill is building RESTful endpoints and authentication flows, demonstrated by SecurityConfig.java and AuthController.java. There is limited evidence of production-grade concerns such as DB migration history, caching and invalidation, background queueing, advanced observability, or deliberate scalability work.

Associate Software Engineer • Middle

Ikaansh Edutech Private Limited • Full-Time

Aug 2025 to Present 1 Year 1 Month New Delhi In office

Worked on backend development for a crypto trading web application using Java and Spring Boot. Built user profile services by aggregating data from Binance and exposing it to the UI. Implemented buy-side transaction workflows including order creation, validation, payment status updates via Binance integration, and tracking agreement and e-sign status through Setu webhooks.

API Design

4/10

How well APIs are designed

Practical REST API design with consistent controller patterns and a shared response wrapper, but limited advanced API-level concerns like versioning strategy, pagination, idempotency keys, or documented error contracts.

Data Layer & Database

3/10

Working with databases

Standard JPA-based data layer with entity relationships and custom repository queries, but no evidence of explicit transaction management, migration history, or tuned SQL/indexing.

Scalability & Performance

1/10

Handling load and speed

Little to no work shown on scalability or performance engineering - no caching strategy, queueing, connection-pool tuning or rate limiting present in the human-authored code.

System Architecture

4/10

Overall system structure

Clear package separation (controllers/services/repositories) and multiple small domain services built end-to-end; architecture is monolithic per service with reasonable module boundaries but no multi-service contracts or deliberate distributed-design tradeoffs.

Security & Auth

5/10

Protecting data and access

Good practical security basics: Spring Security configuration, role-based access rules, BCrypt password hashing, and a CustomUserDetailsService; missing advanced token lifecycle or refresh/revocation patterns.

Reliability & Observability

3/10

Stability and monitoring

Basic reliability and test practices are present - unit tests with Mockito and a global exception handler; limited observability, structured logging, retries, backoff strategies, or metrics/alerts.

Recommendations

Build and operate Spring Boot microservices focusing on REST APIs with role-based auth and unit tests.
Implement CRUD-backed internal services or small e-commerce features such as coupon management and purchase flows.
Extend existing apps with DB migration tooling (Flyway/Liquibase), caching with invalidation, and basic metrics/logging instrumentation.
Develop secure user-auth and session-management features or admin dashboards using Spring Security and JPA.
