StockDaddy

Senior Software Engineer / Full-Stack Engineer

Nov 2021 — Present

StockDaddy is a trading education platform operating large-scale backend systems for course delivery, payments, and operational workflows. My role bridges application engineering and infrastructure operations, managing the entire lifecycle of production services.

Backend Systems

Built and maintained modular backend services using:

• Languages/Frameworks: Node.js, NestJS, TypeScript, REST APIs
• Design: Modular service architecture, robust business logic, and security workflows.
• Identity: Implementation of advanced authentication and role-based access control (RBAC).

Payment and Order Systems

Engineered high-reliability payment workflows and order management systems:

• Integrations: Razorpay gateway, webhook processing with idempotent retry logic.
• Reliability: Automation of course enrollments, coupon systems, and transactional consistency.
• Resilience: Solved for webhook failures, duplicate requests, and transaction integrity.

Admin Platforms and Internal Tools

Developed comprehensive internal administration systems to streamline platform operations:

• UI/UX: React, Next.js, TypeScript.
• Features: Role-based dashboards, enrollment reporting, and operational management tools.

Data Systems

Managed data persistence and caching for high-traffic environments:

• Core: PostgreSQL for relational data, Redis for high-speed caching and sessions.
• Focus: Schema design, query optimization, and transactional safety.

Cloud Infrastructure and DevOps

Operated containerized production systems on AWS:

• AWS Stack: EC2, RDS, S3, ECR, CloudFront CDN, VPC Networking.
• Orchestration: Docker, Kubernetes (EKS).

CI/CD Automation

Designed automated deployment pipelines using GitHub Actions:

• Workflows: Automated container builds, deployment isolation (Dev/Staging/Prod).
• Safety: Improving deployment reliability and reducing lead time for changes.

Security

Implemented production-grade security measures:

• Access: JWT, OAuth, IAM policies, VPC security groups.
• Safety: SSL/TLS configuration and end-to-end encryption.

The Transition to Reliability

Building and operating production systems exposed me to the critical nature of deployment reliability, monitoring gaps, and infrastructure efficiency. This experience shifted my focus toward:

• Infrastructure Architecture (Kubernetes, AWS)
• Deployment Safety (CI/CD, GitOps)
• Observability (Monitoring, Incident Response)
