Sai Pranav Moluguri

Python backend developer with around 5 years of experience across the full software development lifecycle, building REST APIs, services, and data-driven backend systems using Python, Node.js/Express.js, and relational/NoSQL databases. Recent hands-on experience extending backend systems with AI capabilities — LLM integration, RAG pipelines, and LangChain-based workflows — using the Anthropic Claude API. Comfortable working with AI-assisted development tools (Claude Code, Cursor) to accelerate backend delivery, with supporting experience in React.js for front-end integration.

Strong foundation in API design, database schema modeling, authentication/security, and Agile delivery. Also writes technical content on Python and full-stack development, published on Medium.

AI/ML Engineer at Boca Helping Hands (2025-07 – Present)

• Developing and maintaining Python-based backend services and REST APIs to streamline nonprofit appointment operations, supporting scheduling and record-management workflows for multiple service centers.
• Integrating LLM-powered features into backend workflows using the Anthropic Claude API, LangChain, and RAG pipelines to support intelligent document lookups and automated response generation.
• Using AI-assisted development tools (Claude Code, Cursor) to accelerate backend feature development, debugging, and code refactoring, shortening iteration cycles.
• Designing and implementing RESTful API endpoints with structured request validation, JWT-based authentication, and MySQL-backed data models to support concurrent operations across service centers.
• Building supporting React.js components for internal admin dashboards, giving non-technical staff visibility into appointment and automation data.
• Collaborating with nonprofit stakeholders to gather requirements and translate service workflows into backend features, prioritizing reliability and data integrity across environments.
• Building and maintaining embedding pipelines and a lightweight vector store to support semantic search over internal documents, improving retrieval accuracy for RAG-based responses.
• Writing prompt templates and structured output parsing logic for Claude API calls to ensure consistent, validated responses across backend services.
• Optimizing MySQL queries and API response times for high-traffic scheduling endpoints, reducing average response latency during peak service hours.
• Setting up structured logging, error handling, and monitoring for backend services to speed up debugging and reduce production incidents.
• Participating in code reviews and sprint planning, and documenting API contracts and internal tooling to support onboarding and cross-team collaboration.

Software Development Engineer at Cognizant (2021-01 – 2024-08)

• Developed and maintained backend services and REST APIs using Python and Node.js/Express.js across multiple full-stack client projects, including a production matrimonial platform with tiered subscription billing (Stripe) and a large-scale internal web application.
• Designed and implemented JWT-based authentication, MySQL/PostgreSQL relational schemas, and Socket.IO-based real-time messaging for backend services supporting thousands of daily transactions.
• Built and optimized RESTful API endpoints with structured validation, error handling middleware, and AWS S3 integration for secure file storage, using Postman for endpoint testing and regression validation.
• Contributed React.js components and state management (Redux, Hooks) for client-facing interfaces, collaborating with UI/UX designers to implement responsive, accessible front-end features.
• Led backend migration and refactoring efforts, improving API performance and maintainability, and participated in Agile sprint ceremonies, code reviews, and CI/CD pipeline configuration.
• Designed normalized MySQL/PostgreSQL database schemas for users, transactions, and messaging data, adding indexing and foreign key constraints to improve query performance at scale.
• Integrated Nodemailer-based transactional email workflows for account verification, OTP delivery, and subscription confirmations across client projects.
• Automated routine backend tasks and data validation using Python scripting, reducing manual QA effort and catching data issues before production releases.
• Partnered with QA and business teams to triage production incidents, root-causing backend failures and driving fixes to closure within SLA windows.
• Mentored junior developers on backend coding standards, API design conventions, and Git branching workflows, improving overall code quality across the team.
