Who I Am

A developer who enjoys building things end-to-end — from database schemas to pixel-perfect apps.

Adityam Srivastava

I'm a final-year Computer Science Engineering student and a developer who enjoys building things end-to-end — from REST APIs and database schemas to pixel-perfect Android apps.

My core strength lies in Java backend development with Spring Boot, where I've built systems with 40+ API endpoints, geospatial queries, and concurrency-safe transactions. On the Android side, I work with Kotlin & Jetpack Compose following modern MVVM architecture.

Lately, I've been deep into AI engineering — integrating Groq & Gemini LLMs into real applications, and building autonomous agents that automate complex workflows. I also keep my fundamentals sharp — 150+ DSA problems solved on GeeksforGeeks.

Backend Development

Scalable Spring Boot services, secure REST APIs with JWT, normalized PostgreSQL schemas & optimized queries.

Android Development

Modern apps with Kotlin, Jetpack Compose & MVVM — reactive UIs, Coroutines, and clean architecture.

AI Integration

LLM-powered features using Groq & Gemini APIs — from AI advisors to autonomous browser agents.

01 Jul 2026 — Aug 2026 ★ Featured

Auto-Apply AI Agent ↗

Autonomous AI agent that applies to jobs on its own

  • Architected an autonomous, interface-driven web agent using Spring Boot and Selenium that navigates complex React-based UIs and dynamic recruiter chatbots — intelligently extracting live questions and interactive elements.
  • Integrated Groq/Gemini LLMs with a custom model-fallback system to autonomously answer situational questions — selecting pills, radio buttons, textboxes, and formatting dates from contextual prompts.
  • Engineered a 3-layer fault-tolerant JSON parser (Direct → Comma Injection → Regex Extraction) hardened against LLM hallucinations, achieving 100% parsing reliability.
  • Defeated React's synthetic event traps and readonly fields via deep JavaScript injection (PointerEvent / MouseEvent / input events), and replaced brittle sleep() with state-driven DOM polling + volatile thread-safe Pause/Resume/Stop controls.

Customer Relationship Management (CRM) API ↗

Enterprise-style backend for customers, leads, interactions & sales pipelines

  • Built a production-grade CRM REST API following Domain-Driven Design (DDD) and strict N-Tier architecture — Controller → Service → Repository with @Transactional business boundaries.
  • Implemented stateless JWT authentication with BCrypt password hashing and method-level security (@PreAuthorize), restricting destructive endpoints to ADMIN roles only.
  • Enforced the DTO pattern to decouple entities from API payloads — preventing over-posting vulnerabilities — with Jakarta Bean Validation and centralized error handling via @ControllerAdvice.
  • Modeled real sales workflows: paginated & searchable customer endpoints, interaction logging (calls, emails, meetings), and deal-stage transitions across the pipeline.

TransitBooking — Smart Ticketing System ↗

Concurrency-safe passenger booking engine

  • Architected a production-ready booking REST API (Spring Boot 3, Spring Security 6) with database-backed authentication, BCrypt hashing, and role-based access (ADMIN / USER).
  • Solved double-booking race conditions using @Version optimistic locking on seat entities — ensuring safe ticket allocation under concurrent requests.
  • Eliminated N+1 query problems with JOIN FETCH / @EntityGraph and implemented pagination & sorting via Pageable for efficient large-dataset retrieval.
  • Applied the DTO pattern with @Valid input validation and @RestControllerAdvice for standardized error responses with proper HTTP status codes.

FarmYukti Backend — Spatial Agri-Tech Marketplace ↗

Team project — geospatial marketplace connecting farmers & buyers

  • Built a spatially-aware marketplace backend on a normalized 6-table PostgreSQL schema, fully documented with OpenAPI 3.0 / Swagger UI.
  • Engineered a geospatial land registry using PostGIS + Hibernate Spatial — mapping farm boundaries from exact GPS coordinates (SRID 4326) and verifying land ownership before permitting listings.
  • Implemented proximity-based discovery with ST_DWithin spatial queries — buyers discover active crop listings within a radius of their location.
  • Secured the platform with JWT + strict RBAC separating FARMER and BUYER workflows; atomic transactions deduct inventory on order placement, preventing overselling.
  • Collaborated with a teammate who built the Android client (Jetpack Compose, MVVM, Retrofit) consuming these REST APIs.

FarmYukti — Agri-Tech App (Android) ↗

AI-powered farming platform for farmers

  • Developed a full-stack agricultural app using 100% Jetpack Compose, MVVM architecture, and Firebase for a modern, scalable, and reactive user experience.
  • Integrated Google's Gemini AI API to deliver features like an AI farming advisor, crop recommender, and plant disease diagnosis tool.
  • Engineered a real-time marketplace using Firebase (Auth & Firestore) and Cloudinary, enabling secure transactions and media uploads.
  • Implemented state-driven UI for a live market price dashboard (Retrofit) and user authentication.

Invoice Generator ↗

PDF invoice app for businesses

  • Developed a modern Android application using Kotlin and Jetpack Compose to efficiently process business and client data into detailed PDF invoices via the iText PDF library.
  • Architected the app for optimal performance with Coroutines for async operations, ViewModel for state management, SharedPreferences, and robust internal file handling.
