Intern – Software Engineer

  • Implemented inventory management, accounting, and CRM modules using Python and Flask within the ERP system to help the business manage inventory levels and track financial transactions more efficiently, along with custom reports, dashboards, and analytics to provide business insights, reducing manual work by 50% and improving inventory management accuracy by 85%.
  • Formed ERP system requirements and specifications document based on meetings with key business stakeholders to understand their needs and planned development of new capabilities aligned with business growth.
  • Designed a relational database schema in MySQL to organize business data for reports and analysis with stored procedures and database triggers to enforce business logic and data integrity.
  • Created user guides and admin manuals to support onboarding new users and documentation for users covering system navigation and module functions and conducted training to help employees adopt the new ERP tools.

Projects

  • TransactViaMe is a cloud-native, event-driven payment backend platform designed to simulate real-world payment processing workflows, emphasizing scalability, reliability, and observability. The system orchestrates asynchronous payment workflows across authorization, settlement, and ledger services using Java and Python, connected via Kafka with PostgreSQL and Redis to ensure durable and cached state.
  • The platform features high-throughput Kafka pipelines capable of processing 50K+ payment events per minute, with idempotent consumers, retries, and failure recovery, maintaining data integrity during service restarts and load spikes. Automatic horizontal scaling is enabled on AWS EKS using Kubernetes with Horizontal Pod Autoscaler, sustaining API response times under 200 ms under synthetic stress testing with k6 and Locust.
  • Supporting services and tooling are developed in TypeScript, with stress and failure testing conducted across pods and Kafka consumers. Observability is ensured through Prometheus, Grafana, and centralized logging, providing full visibility into system performance, throughput, and resilience.
  • TransactViaMe demonstrates the design and operation of distributed, event-driven backend systems that are scalable, fault-tolerant, and production-ready, which can be easily integrated to any frontend interface.
June 2025 - July 2025
  • Built a C++20 tool for Windows and Linux that performs incremental backups from multiple source directories by detecting file changes using file size and modification time, with a binary metadata cache to prevent redundant copying across runs.
  • Parallelized scanning, hashing, and copying phases using a custom thread pool to efficiently manage concurrent tasks, maximizing resource usage and reducing synchronization time through overlapping operations. Tested with over a million files, maintaining a low memory footprint of just a few megabytes.
  • Designed a disk-aware per-source copy mechanism using thread-safe queues with serialized and parallel modes for peak throughput. Ensured data integrity by updating metadata only after verified copies and enabling automatic retries on failure.
  • Implemented structured logging, UTF-8 support for multilingual file and folder names and configured the system to be fully driven by a user-editable file supporting flexible sync modes, source exclusions, and stale file cleanup.
July 2023 - May 2024
  • Launched a website that integrates a CNN model to classify cyclone intensity with 94.5% accuracy using IR(Infrared) images from the MOSDAC website, categorizing cyclones into levels 1 to 5, and providing real-time insights into cyclone severity.
  • Trained a T5 transformer model to generate multilingual safety guidelines and precautionary measures tailored to each cyclone level, enhancing accessibility and improving response strategies for diverse audiences.
  • Integrated OpenWeatherMap API providing additional weather-related information enhancing website’s functionality.
  • Setup Twilio API sending SMS alerts with cyclone intensity and precautionary guidelines, providing timely information to users.
July 2022 - May 2023
  • Developed an Android Application to help people with hearing impairments improve their speaking skills using lip-synced animations and dynamic sound represented in line graphs.
  • Employed GMM – HMM (Hidden Markov Model with Gaussian Mixture Model) to perform Speech Recognition and Waveform Similarity Analysis to identify the accuracy of the words spoken by the user.
December 2022 - December 2022
  • Installed and configured Snort on Kali Linux, modifying its configuration to meet network security needs, and setting up log storage to capture traffic data and monitor real-time network activity.
  • Customized Snort rule configurations to drop malicious ICMP and TCP packets, mitigating unwanted traffic and reinforcing network defenses against reconnaissance and DoS attacks.
  • Executed Nmap scanning from an external machine on the IDS configuration to assess Snort’s performance in identifying and logging irregular traffic, confirming its detection capabilities.

December 2022 - December 2022
  • Simulated UE Nodes equipped with 5G mmWave Antennas and IPv6 interacting with gNB Nodes using MiMo with Beam Forming and TDMA to access internet at 1Gbps Speeds and Low Latency.
  • Operated NS – 3 along with NetAnim and 5G – LENA Modules with NR to visually simulate how the gNB Nodes interact with the UE Nodes to send and receive packets.
  • Visualized and analyzed the antenna design using MATLAB, specifically studying and understanding the modifications made to optimize it for 5G frequency bands and beamforming techniques.
  • Received an Internship Certificate for completing the training and project on 5G.
July 2022 - July 2022
  • Connected a MySQL Database server to an EC2 instance on AWS to run a node.js application.
  • Launched another EC2 instance for NGINX and configured the application to run on this proxy NGINX server.
  • Acquired an Internship Certificate for completing the training and project on AWS.
July 2021 - May 2022
  • Devised an Android Application to provide user-friendly visual password solutions that prioritized optimal security and ease of password entry for individuals with dyslexia, combining visual cues, multi-touch gestures, and customizable features.
  • Built the touch pattern capture and comparison module to record multi-touch gestures accurately on images, enabling intuitive and interactive password creation leveraging gestures such as tapping, swiping, and holding.
  • Innovated a grid overlay on images, serving as a visual guideline for password entry, ensuring accuracy and ease of use.
  • Applied a comparison mechanism to validate entered passwords against stored ones, assuring authentication accuracy.
