01 / EXPERTISE
Depth where it matters.
Perspective across the stack.
Architecture, implementation and delivery—connected by a practical understanding of how systems behave in production.
Cloud & delivery
Repeatable environments and delivery pipelines that support reliable releases.
Data & events
Event-driven integrations, effective caching and dependable data services.
ACROSS THE EXPERIENCE
React & Angular · System design · SOLID & clean architecture · API testing · Performance optimization
02 / SELECTED PROJECT AREAS
Complexity, made useful.
Professional engineering experience and hands-on project work.
NETWORK INTELLIGENCE
SIGNALS → CONTEXT → INSIGHT
PROFESSIONAL EXPERIENCE / TELECOM
Network analytics & context services
Metadata APIs, KQI calibration and asynchronous context workflows for the REA engineering domain.
Explore the architecture ↗
API → validation → context orchestration → metadata and calibration repositories. Redis supports caching, while asynchronous tasks support longer workflows.
Key concerns: clear DTO mappings, predictable API errors, cache lifetime and failure-aware task completion.
SMALL API. SOLID FOUNDATIONS.

PRACTICE PROJECT / BACKEND
People Manager API
A focused CRUD application demonstrating separation of concerns, persistence and service/controller testing.
Explore the architecture ↗
PersonController → PersonService → PersonRepository → PostgreSQL. Request and response DTOs isolate the API from persistence details.
Validation, consistent exception handling and focused tests keep the application understandable and extensible.
No projects in this category.
03 / HOW I BUILD
Clear thinking.
Strong foundations.
Start with the problem. Make the trade-offs explicit. Build only the complexity the product needs.
- 01
Understand the outcome
Users, workflows, constraints and non-functional requirements.
- 02
Design the boundaries
Domain models, API contracts, data ownership and failure paths.
- 03
Deliver with confidence
Incremental implementation, meaningful tests and performance optimization.

THE ENGINEER BEHIND DEEPRAVIX TECHNOLOGIES
Hi, I’m Deepak.
My work spans Java backend development, microservices, telecom analytics and cloud delivery. I enjoy turning complicated requirements into systems that other engineers can understand, operate and evolve.
I also use AI-assisted tools like GitHub Copilot to move faster while keeping code quality high.
