PROFESSIONAL EXPERIENCE

RSOFT Systems & Services Pvt. Ltd

Full-Stack Python Engineer (Cloud & AI Exposure) Hyderabad, India · Jan 2023 - Dec 2023

•Built and maintained Python-based microservices for product catalog, search, and recommendations using FastAPI/Django and PostgreSQL, adding indexing, pagination, and caching that kept key APIs responsive and stable even during peak traffic periods.

•Containerized services with Docker on Linux servers and deployed them to AWS EKS, automating deployments with bash scripting and configuring deployments, services, and ingress with an Application Load Balancer; implemented CI/CD pipelines with GitHub Actions, reducing manual deployment effort and improving release reliability

•Experimented with LLM-based text embeddings and vector similarity search to add semantic product search and "similar items" recommendations as a proof-of-concept, improving relevance compared to the existing keyword-only approach and laying the groundwork for future RAG-style retrieval features.

•Designed event-driven pipelines with Kafka and AWS Lambda to ingest clickstream and order events, enabling downstream person- alization and analytics without impacting user-facing API performance.

•Collaborated with frontend engineers on a React + Next.js storefront, designing and integrating REST APIs for real-time product filtering and checkout flows, which improved checkout reliability and simplified frontend-backend integration.

•Worked in an Agile/Scrum environment, contributing to sprint planning, code reviews, and production issue triage with root-cause analysis, helping the team deliver features iteratively while keeping the platform stable.

•Contributed to the development of a scalable and reliable e-commerce platform by using SQL and Lambda-based event processing, which improved peak traffic handling and reduced deployment issues.

Full-Stack & DevOps Engineer Hyderabad, India · Sep 2021 - Dec 2022

•Developed and maintained secure Python-based APIs for account management, transactions, and audit trails using Django REST Framework/FastAPI and PostgreSQL, automating operational tasks with python and bash scripts, enforcing strong validation and idempotency so invalid or duplicate transactions were prevented before they reached the database.

•Implemented CI/CD pipelines using GitLab CI, Jenkins, and Ansible alongside Docker to build, test, and deploy services to AWS, reducing manual steps in the release process and making deployments more predictable and less error-prone.

•Deployed services on AWS EC2 and EKS within a VPC on Linux servers, configuring security groups, IAM roles, and Application Load Balancers to strengthen security and improve reliability of internal service-to-service communication.

•Used Kafka and Amazon SQS for event-driven processing of transaction and audit events, allowing new reporting and notification consumers to be added without changing core transaction services.

•Built and integrated internal dashboards using React and Tailwind CSS to display transaction summaries, risk flags, and system health, which helped operations teams quickly spot anomalies and investigate issues, improving incident response time.

•Collaborated with product and operations teams to refine requirements, manage rollout risks, and support production, improving alignment with technical implementation and regulatory/business needs.

•Helped increase the reliability and observability of the fintech platform by integrating monitoring with AWS CloudWatch and implementing logging best practices, making it easier to support secure, compliant transaction flows and operational monitoring.

Software Engineer

Hyderabad, India · Jan 2020 - Aug 2021

•Built and enhanced web applications for patient records, appointments, and billing using Django/Flask and MySQL, supporting daily clinical and administrative workflows and reducing manual paperwork for staff.

•Developed responsive UI components and dashboards with React, HTML, and CSS so staff could search patient data, manage schedules, and review reports more quickly, improving usability compared to earlier interfaces.

•Containerized applications with Docker and deployed them behind Nginx on Linux servers, using Ansible for configuration manage- ment, which simplified environment setup and improved stability across different deployments.

•Wrote unit tests with pytest for key backend modules and added Swagger/OpenAPI documentation for APIs, increasing confidence in changes and making it easier for other teams and clients to integrate with the system.

•Worked with cross-functional stakeholders to clarify requirements, solve production issues, and roll out incremental improvements, helping the system evolve without disrupting day-to-day clinical operations.

•Contributed to smoother clinic operations by making internal tools more reliable and user-friendly for non-technical staff.

PROJECTS

AI-Powered Resume Matching & Job Insights Platform

•Developed a Python-based service that converts resumes and job descriptions into text embeddings and uses vector similarity search to match candidates to roles more intelligently than keyword search, as a learning project in applied AI.

•Integrated OpenAI-style LLM APIs and LangChain to generate job insights and explanations, exposed via FastAPI endpoints, and deployed the service as a Docker container on AWS, following the same CI/CD practices as other services.

Scalable E-Commerce Platform with ML-Driven Semantic Search

•Designed backend services for product catalog and search using FastAPI and PostgreSQL, including filters, sort options, and pagination suitable for large catalogs.

•Implemented ML-driven semantic search using embeddings to rank similar products and containerized the microservices, deploying them on AWS EKS behind an Application Load Balancer, with CloudWatch monitoring for API performance, as an exploratory project in semantic search.

Cloud-Native DevOps Infrastructure & CI/CD Automation

•Built infrastructure-as-code templates with Terraform to provision AWS resources such as VPC, EC2/EKS, security groups, and RDS for application environments.

•Set up CI/CD pipelines (GitHub Actions / GitLab CI) to run tests, build Docker images, push to ECR, and update Kubernetes deployments with health checks and basic rollback strategies, improving deployment reliability and developer productivity.
