Mohanraj builds backends that scale.

Java and Spring Boot engineer building secure banking platforms, ML-powered loan engines, and algo trading systems that help CFAs and CAs manage their clients. B.E. CSE (AI and ML), Class of 2026.

About

Backend first. Finance always.

I'm a Computer Science (AI and ML) graduate from S.A Engineering College, Chennai, but most of what I know was learned by shipping real systems: banking platforms, loan engines, and trading software, where a rounding error is a bug report and a race condition is a lawsuit.

My core stack is core and advanced Java with Spring Boot (Spring Security, Spring Data JPA, Hibernate), built on fundamentals that don't go out of fashion: SOLID design, ACID-safe data modeling, and security-first REST APIs.

The work I love most sits at the intersection of software and capital markets: rule-based trading engines and client-management platforms for CFAs and Chartered Accountants.

Algo and rule-based trading systems

Seamless software for CFAs and CAs to run their clients' portfolios. Strategy in, execution out.

Advisors define the rules once. The system does the rest.

Finance professionals think in rules: allocation caps, entry and exit conditions, risk thresholds. I turn those rules into reliable, automated execution with engines that evaluate conditions, act consistently, and keep a full audit trail for every client.

  • Rule engines that encode investment strategies as testable, versioned logic
  • Transactional integrity with the same ACID discipline as my banking systems
  • Role-based access and audit logs so every action is traceable per client
  • One clean platform for advisors to manage many portfolios at once

Things I've shipped

01

AI-Powered Smart Loan Approval System

Secure online banking platform with an ML microservice. FastAPI and Scikit-learn predict loan eligibility from real transactional behaviour: salary credits, bill payments, balances, and repayment history. Applications clearing 70% model confidence are auto-approved and disbursed; the rest route to managers.

02

College Event Management System

Scalable event platform with RESTful APIs for registration, applicant tracking, and administration. JWT authentication secures every role, and the whole app ships as a Docker container for one-command deployment.

Online Banking Application

Secure monolithic banking app on layered architecture: Spring Security and JWT for auth, Hibernate with Spring Data JPA for transaction management, and ACID-compliant database design, because in banking "mostly consistent" isn't a thing.
