Pashyaa Technologies is a senior-led Java/Spring engineering company helping software and product teams modernize existing Spring Boot systems, deliver APIs and integrations, improve reliability and security, and add practical AI and RAG capabilities. Start with a defined assessment or engineering workstream and expand into ongoing managed engineering when it makes sense.
Planning to upgrade or build on an existing Java/Spring system?
We review the architecture, framework and dependency versions, APIs, data access, tests, security and delivery pipeline, then give you prioritized findings and a modernization roadmap.
Scope and delivery time depend on application size and assessment depth; broader assessments are scoped before work begins. An engineering review — not a penetration test or a compliance certification. Implementation quoted separately.
What we do
Four capabilities around one focus: existing Java/Spring applications. Fixed-scope offers carry an indicative price on the services page; larger workstreams are scoped before they are priced.
Java and Spring Boot upgrades, dependency and framework modernization, refactoring, SQL and performance work, and stabilization of existing production systems.
Senior-led, drawing on more than a decade of hands-on Java/Spring engineering in regulated software — banking, healthcare and cross-border compliance.
REST APIs, microservices, and third-party and event-driven integrations, built into or alongside existing Java/Spring systems.
Spring Boot APIs and microservices with Kafka-driven asynchronous workflows on a US pharmacy benefits platform, and REST APIs with NestJS middleware behind a global partner and retailer portal.
Secure code review, security-audit remediation, and security design review for Java and LLM systems.
Vulnerability remediation and security-audit remediation across banking and healthcare platforms, static-analysis remediation on an enterprise portal, and the secrets, auth and retrieval boundaries in InfoYog.
Building RAG and LLM features into existing Java/Spring Boot systems.
InfoYog, our own production AI assistant: Java 21, Spring Boot 3.x, pgvector-backed retrieval and RAG answer routing.
Who we work with
How engagements start
A bounded review of an existing Java/Spring application. You receive prioritized findings, an actionable modernization roadmap and a recommended next workstream.
We own one scoped outcome: an upgrade, API or integration, stabilization work, security remediation or a practical AI/RAG feature. Scope, responsibilities and acceptance criteria are agreed before implementation begins.
Where it makes sense, the work continues as managed Java/Spring engineering, with senior accountability for architecture, implementation review and client communication. Quoted per engagement.

FAQ
Quick answers. If your situation is different, tell us about the application.
Usually with a bounded assessment of an existing Java/Spring application. From there we deliver a defined sprint or workstream with agreed scope and acceptance criteria and, where it makes sense, continue as managed Java/Spring engineering. Work is delivered remotely from India with flexible EU/US overlap, under a B2B contract with Pashyaa Technologies Pvt. Ltd.
Yes. We routinely work under NDA and follow IP protection best practices including access controls, least-privilege permissions, and secure development workflows.
Java 17 and 21, Spring Boot and Spring Security are the core, with JPA/Hibernate, PostgreSQL and Kafka on the data side, and React with TypeScript where full-stack delivery is needed. AWS or GCP, Docker and CI/CD for delivery.
Tests with JUnit, Mockito and Testcontainers, code review on every change, and CI/CD that runs them. We work inside your existing SDLC, conventions and security baselines rather than imposing our own.
The Java & Spring Boot Modernization Assessment is the smallest: a focused assessment of a single service starts from $900, and broader assessments are scoped before work begins. It is a common starting point before a defined workstream.
