Ashok K.

Senior Java/Spring Boot engineer with 16+ years of experience designing and modernizing backend systems for fintech, enterprise, and SaaS products. I help teams build scalable microservices, optimize performance, and migrate legacy systems to cloud-native architectures on AWS. Recent work includes a multi-tenant lending platform, a test-management SaaS, and a legal-tech case management system with RAG-based search. I’m comfortable leading architecture reviews, mentoring developers, and delivering production-ready code with CI/CD, Docker, and Kubernetes. I combine deep backend expertise with modern AI tooling to deliver smarter, more efficient applications and faster development cycles. Core strengths Backend & Cloud: Java, Spring Boot, Spring Security, Spring Cloud, Microservices, REST APIs, AWS (ECS Fargate, EC2, S3, RDS, ALB), Docker, CI/CD Databases & Performance: PostgreSQL, MySQL, Oracle, SQL tuning, Redis caching, query optimization AI & LLM workflows: RAG (Retrieval‑Augmented Generation) for domain search (case law, documents, tickets, logs) AI‑assisted development using Claude Desktop, Codex, and similar tools to accelerate design, refactoring, and test generation Selected work Multi-tenant lending platform (fintech SaaS) – Designed Spring Boot microservices on AWS (ECS Fargate, RDS, ALB). Introduced Redis caching and query optimization; reduced average API response time from ~800ms to ~180ms. Test management SaaS – Built a system to manage manual Excel test cases with diagrammatic process views and Selenium automation integration; used by multiple QA teams as a multi-tenant service. Stripe payment integration. Legal-tech case management system – Implemented RAG-based case search, evidence transcription workflows, and automated court hearing events; multi-tenant SaaS used by several law firms.
