About

As an SDE-2 at Ericsson, I specialize in architecting, developing, and scaling high-throughput, distributed backend systems. I focus deeply on turning complex High-Level Designs (HLD) into reliable, modular, and maintainable services using clean Low-Level Design (LLD) principles, SOLID patterns, and robust algorithmic strategies. Core Architecture & Engineering Expertise: High-Level Design (HLD): Microservices architecture, distributed task orchestration (Celery + Redis), asynchronous background workflows, latency optimization, and secure API gateways. Low-Level Design (LLD): Clean code practices, implementation of Creational and Behavioral design patterns (Factory, Strategy, Singleton), and scalable schema modeling (SQL/NoSQL). Problem Solving: Data Structures & Algorithms (Active practitioner tracking algorithmic optimization and concurrency management). Technical Ecosystem: Languages: Python, Java Frameworks: FastAPI, Flask Databases & Caching: MySQL, MongoDB, MySQLx, Redis Infrastructure & Cloud: Docker, CI/CD Pipelines, Azure IoT Edge Driven by building scalable software infrastructure that directly cuts operational execution time and optimizes multi-tenant system performance.

Promoted

Dec 2024 – Present · 1 yr 6 mos · Remote

Architected and implemented an automated product provisioning and deployment platform from scratch utilizing FastAPI/Flask, eliminating manual installation dependencies across distributed environments.
Engineered a distributed job orchestration engine using Celery and Redis to handle real-time, asynchronous task routing, successfully scaling performance to support 1,000+ concurrent processing nodes while cutting API latency by up to 90%.
Designed a decoupled validation framework applying structural and behavioral design patterns (Factory, Strategy, and Singleton), ensuring absolute compliance with SOLID principles and reducing cross-functional execution overhead by 2–3 days.
Optimized data access layers using MySQL and NoSQL JSON indexing via MySQLx, scaling database throughput and managing memory constraints by implementing smart server-side caching strategies.
Streamlined end-to-end continuous integration and container deployment pipelines utilizing Docker, secure X.509 certificate configurations, and role-based access controls (RBAC) across Azure environments.
