Suryansh Saxena

Software Engineer with 4+ years of experience building and operating production systems across payroll, EdTech, education, and transaction-intensive platforms. Core strengths include Python, Django, FastAPI, PostgreSQL, Redis, and Celery, with hands-on experience in REST API design, asynchronous workflows, database optimization, third-party integrations, and AWS-based deployments. Experienced in production troubleshooting, root-cause analysis, automated testing, and backend-heavy full-stack collaboration with ReactJS, NextJS, and Angular.

Software Engineer at RevolutionES (2025-08 – Present)

• Built and maintained production payroll and workforce-management services using Python, Django, Django REST Framework, PostgreSQL, Redis, and Celery, supporting transactional validation, approvals, and accounting exports.
• Developed asynchronous Celery/Redis workflows to synchronize payroll data with third-party systems, including retry, validation, and recovery handling for failed integrations.
• Redesigned approval-workflow APIs and administrative modules, reducing manual operational effort by approximately 25% for payroll and workforce operations.
• Investigated production incidents involving inconsistent payroll data, failed synchronizations, slow queries, and workflow failures through root-cause analysis and durable fixes.
• Contributed to backend design decisions involving service boundaries, workflow orchestration, data consistency, error handling, and integration-failure recovery.

Software Engineer Lead at Green Rider Technology (2024-01 – 2025-06)

• Earlier supported client AI model-training and prompt-evaluation operations before transitioning into backend product engineering.
• Built and maintained backend infrastructure for a student-training platform used by 10,000+ students and serving 100,000+ daily API requests using Python, FastAPI, SQLAlchemy, SQLModel, and PostgreSQL.
• Designed 50+ FastAPI endpoints with reusable schemas and validation; PostgreSQL query tuning and Redis caching reduced API response times by approximately 30%.
• Implemented OAuth 2.0 and JWT authentication and contributed to system-design decisions around secure API access, service integration, and backend scalability.
• Tuned PostgreSQL on AWS RDS through query-plan analysis, indexing, partitioning-related improvements, and Redis caching to maintain responsive performance as load increased.
• Collaborated with frontend engineers on React-based interfaces, defining API contracts and integrating backend workflows into user-facing product experiences.

Associate Software Engineer at Pure Software (2022-01 – 2023-12)

• Developed scalable Python/Django APIs for an education platform serving 50,000+ students, with backend and database optimizations reducing application response time by approximately 25%.
• Built Flask backend modules for an iGaming platform processing millions of transactions, using server-side caching, database optimization, and data-validation safeguards.
• Expanded Pytest-based automated test coverage and integrated test suites into CI/CD pipelines, increasing coverage by approximately 40%.
• Authored API documentation, validated high-traffic workflows using Postman, participated in code reviews, and supported release-quality improvements across client projects.
• Investigated production and data-integrity issues across client projects, performing root-cause analysis and supporting time-sensitive fixes.
• Contributed to ReactJS and AngularJS interfaces and API integration for enterprise applications, providing full-stack support while remaining primarily focused on backend delivery.
