Projects
Alongside my professional experience, I build software systems, backend platforms,
and engineering projects to explore software architecture, backend development, distributed systems,
and AI-enabled applications.

CURRENT WORK
Modular Backend Platform
I'm currently expanding a modular backend platform built with
Java and Spring Boot. My current focus is on service decomposition,
API Gateway integration, secure service-to-service communication,
and documenting the architectural decisions behind each component.
- Architecture Documentation
- Service-to-Service Communication
- API Gateway
AI-Enabled Systems
Software systems that integrate machine learning capabilities
to support intelligent decision-making and data-driven business
processes.
Leads - A CRM Module
This project explores the architecture of a web application
that includes a CRM module designed to enhance lead
management through data-driven insights. The system
incorporates a lead scoring capability that predicts
conversion probability using a machine learning model
exposed through a decoupled ML service.

Modular Backend Platform
A reference implementation of a modular backend platform built
with Java and Spring Boot. Each service owns a specific business
capability, exposes REST APIs, and is designed to operate
independently while collaborating as part of a larger backend
system.
Authentication Service
This project documents the architecture and implementation
of a reusable authentication service built with Java,
Spring Boot, and Spring Security. It demonstrates modern
authentication practices using JWT, role-based authorization,
secure API design, and a modular architecture intended for
distributed systems.

Lead Service
This project documents the architecture and implementation
of a lead management service built with Java and Spring Boot.
It centralizes the lead lifecycle while supporting configurable
assignment workflows, business rules, and RESTful APIs.

Inventory Service
This project documents the architecture and implementation
of an inventory management service built with Java and
Spring Boot. The system provides centralized inventory
tracking, stock movement management, and scalable REST APIs.
