Hi, I'm Brijesh :)
I build scalable backend systems and APIs that run reliably in production. Over the past 3+ years, I’ve worked across Fintech, MarTech, and SaaS, delivering up to 80% automation improvements and optimizing system performance at scale. My core stack includes Java, Spring Boot, REST APIs, and AWS, and I’m currently building AI-powered applications using LLMs and RAG pipelines.
Tech Stack Behind My Work
Backend Engineering
Developed scalable backend applications using Java with strong OOP principles.
Built production-grade APIs and microservices with focus on scalability and reliability.
Used Hibernate ORM for efficient database interaction and relational data handling.
Designed distributed microservices for scalable and fault-tolerant systems.
Developed and optimized REST APIs with focus on performance and clean design.
Databases
Managed complex queries and optimized database performance using PostgreSQL.
Built and maintained relational databases using MySQL for web applications.
Used MongoDB for flexible NoSQL data storage in modern applications.
DevOps / Deployment
Containerized applications using Docker for smooth deployment and portability.
Managed container orchestration and scaling using Kubernetes clusters.
Deployed applications on AWS cloud with scalable and secure infrastructure.
CI/CD & Automation
Built CI/CD pipelines for automated build, testing, and deployment workflows.
Automated build and deployment pipelines using Jenkins CI/CD tools.
AI / Machine Learning
Implemented AI/ML-based solutions for automation, prediction, and smart decision-making.
Built RAG pipelines to enhance AI responses using document search and vector databases.
Used LangChain to build AI agents, workflows, and LLM-based automation solutions.
Developed Agentic AI systems capable of reasoning, planning, and executing tasks.
Used Pydantic for strong data validation, schema modeling, and API request handling.
