Software Developer

Pain itself is very important, it is followed by consequences, but some work and pain are great.

Duties to choose and work, and the relief from pain, are true options. Anyone can achieve everything and follow it. No one can blame the pain that happens during duties. And everything belongs to him. Desire leads to what is said as the greatest duty. But those who are connected are not rejected.

Project Experience

Hybrid English–Spanish Translation System

April, 2025

Developed a hybrid translation engine combining dictionary-based, rule-based, and trigram Markov models with 14k+ lexical entries and 68 grammar rules.
Implemented compressed tries, perfect hashing, and sparse matrix optimizations to ensure fast lookups and efficient memory usage.
Built a seven-stage preprocessing pipeline with normalization, regex handling, contraction expansion, and semantic truncation, optimized with multi-threading for 42.7 words/sec throughput in 128MB.
Evaluated on 5k+ test cases, achieving 87.3% phrase-level accuracy with sub-second response times.

Course Management System – University Enrollment Platform

April, 2025

Designed and deployed a relational database (20+ tables) with robust constraints and relationships, ensuring reliable data management at scale.
Developed backend modules in SQL/PHP to automate GPA calculation, instructor records, TA/Grader assignments, waitlists, and student feedback tracking.
Optimized queries and enforced integrity rules through rigorous testing/debugging, improving system stability and accuracy.Built a functional Android application with real-time connectivity, enabling seamless course registration, grade access, waitlist management, and instructor oversight.
Created clean, intuitive XML-based UI layouts and Java logic, delivering an improved user experience for both students and faculty.Partnered in a 3-member team, contributing across all phases (database, backend, mobile app) and delivering a fully integrated system demo.

N-Body Gravitational Simulation

December, 2024

Developed a physics-based N-Body simulation in C++ to model gravitational interactions of celestial bodies using Newton’s law of gravitation and leapfrog numerical integration.
Implemented object-oriented design with encapsulated CelestialBody and Universe classes, handling force calculations, velocity/position updates, and memory management with smart pointers.
Integrated SFML for real-time visualization and audio, rendering dynamic celestial motion with scalable coordinate transformations and interactive user controls.

Multithreaded Producer-Consumer System with Deadlock Analysis

February, 2025

Implemented a multithreaded producer-consumer system with 30 producer threads and 50 consumer threads, synchronized using POSIX mutexes and condition variables.
Designed four independent circular buffers (one per item type) with head/tail pointers, item counters, and serial number tracking to manage concurrent access.
Conducted deadlock probability analysis by varying buffer sizes (1500–2000 slots) and consumer workloads (1000–3000 units), identifying a 50% deadlock threshold at ~1800 slots.
Developed automated stress testing and process monitoring techniques to detect and resolve deadlocks, ensuring system robustness under heavy loads.
