Alok Maddheshiya

I am a Software Development Engineer with strong expertise in backend development, distributed systems, and problem-solving. I hold a B.Tech in Electronics and Communication Engineering from Madan Mohan Malaviya University of Technology (CGPA 7.93).

Currently, I am working as an SDE-I at Physics Wallah, where I have built scalable Kafka-based pipelines for high-throughput data ingestion, implemented Redis caching to reduce read times by 90%, and developed robust producer-consumer workflows for real-time data streaming. Previously, I worked as a Software Developer at Paiteq Private Limited, developing backend systems with NestJS, Node.js, PostgreSQL, MongoDB, and Drizzle ORM, where I engineered secure APIs, OTP verification with Redis-based rate limiting, and real-time features like group chat message forwarding, reactions, and mentions.

Alongside my industry work, I also have 1+ year of teaching experience as a Data Structures & Algorithms Instructor/TA at Getsdeready, where I delivered 500+ hours of teaching, mentored 1000+ students, and guided them in mastering C++ and DSA for coding interviews and competitive programming.

Technical Skills:
Proficient in Java, Python, Golang, C++, TypeScript, JavaScript, SQL, PostgreSQL, MongoDB, Redis, Kafka, Docker, Kubernetes, AWS, and more.
Experienced with backend frameworks (NestJS, Spring Boot, Express, Django), frontend frameworks (React, Next.js), and DevOps tools (Grafana, Jenkins, CI/CD).

Competitive Programming Achievements:
Knight Badge on LeetCode (1885 rating)
4★ on CodeChef (1828 rating, Global Rank 87 in Div-3 among 21k+ participants)
Specialist on Codeforces (1438 rating)

Qualified GATE CSE – 2023

Notable Projects:
Ecommerce App (MERN stack) – Developed a full-stack platform with category-wise product listings, dynamic filters, and real-time cart updates using AJAX.
Real-time Systems – Built scalable solutions with Kafka, Redis, and WebSockets for notifications, chat systems, and bulk user onboarding.
With a strong mix of industry experience, teaching expertise, and competitive programming achievements, I bring the ability to simplify complex concepts, build scalable software, and mentor others in problem-solving and system design.
