Backend Java Developer

Dev Keshav Hire

"I love Java, clean architecture, and everything that has something to do with logic."

Backend Java Developer passionate about building scalable backend applications with Java, Spring Boot, REST APIs, PostgreSQL, and WebSockets. I enjoy designing clean, maintainable systems and solving complex logical problems through code.

About Me

Backend Architecture & System Design

I am a backend-focused computer science engineer who thrives at the intersection of logical algorithmic thinking and software engineering. I find joy in designing efficient data flows, architecting relational database schemas, and writing thread-safe Concurrent structures in Java.

Instead of simply building basic features, I focus on system reliability, clean architecture principles, and latency constraints. Whether it's processing real-time game events over highly responsive WebSockets or writing custom token parsers with exact operator priority, I prioritize testing, structured patterns, and clean logic.

Core Philosophy

Problem Solving First

Solving challenging logical problems is my primary driver. I look at coding as translating complex real-world logic patterns into robust structures. I prioritize deep analysis before implementation, structural scalability over fast hacks, and building defensive architectures that prevent faults rather than patching them later.

"A week of debugging can save an hour of logical architecture planning. I prefer planning."

Logical Thinking

Deducing optimal paths using sound engineering logic and design layouts.

Analytical Thinking

Examining system logs and performance parameters to isolate scaling bottlenecks.

Backend Architecture

Structuring layers (Controller, Service, Repository) around SOLID design principles.

Debugging

Tracing code stacks systematically to pinpoint and resolve concurrency conditions.

Continuous Learning

Keeping pace with recent Java releases, Spring APIs, and architectural patterns.

Collaboration

Working alongside frontend developers and peers to engineer cohesive systems.

Portfolio

Featured Projects

XO Arcade

REAL-TIME MULTIPLAYER SYSTEM

A highly interactive real-time multiplayer Tic Tac Toe platform. The platform handles parallel game states, real-time message broadcasting, and player presence tracking using low-latency asynchronous WebSockets.

  • Real-time Multiplayer (WebSocket communication)
  • Social system: Friend requests & Live Notifications
  • Persistent PostgreSQL DB for Match history & profiles
  • Supabase JWT Authentication integration
Spring Boot Java PostgreSQL WebSocket JSP Supabase

Equation Evaluator

ALGORITHMIC PARSER

A core Java mathematical expression evaluator. It parses complex algebra equations containing BODMAS precedence rules, arbitrary parentheses nesting levels, and exponent operations, converting them into evaluation trees without relying on script libraries.

  • Custom Lexer & Parser (no script-engine dependencies)
  • BODMAS & Operator Precedence rules
  • Recursive descent parser structure
  • Robust error messaging for invalid operators/braces
Java Algorithms Data Structures Compiler Theory
