Built and maintained web crawlers, background workers, and job queues using Go routines and channels for concurrent data processing. Wrote robust unit and integration tests using Go's testing framework, achieving 90% code coverage and improving deployment confidence. Worked on CI/CD pipelines (Bitbucket Pipelines, GitHub Actions) to automate testing, linting, and deployment of Go services.

Developed and maintained internal tools using Retool, enabling business teams to interact efficiently with backend systems like PostgreSQL, REST APIs, Firebase, and GraphQL. Integrated third-party APIs (e.g., Stripe, Airtable, Salesforce) into Retool apps to streamline data visibility and control. Wrote JavaScript logic and transformers to extend Retool functionality, improving app performance and business logic handling. Designed user-friendly interfaces and forms with role-based access controls, ensuring secure and intuitive user experiences. Collaborated closely with product managers and backend engineers to prototype, iterate, and deploy tools rapidly with a low-code approach. Used version control (Git) and Retool environments to manage staging and production deployments effectively. Conducted internal demos and onboarding sessions for non-technical stakeholders, increasing adoption of internal tools across departments.

Implemented two features resulting in the adoption of enterprise licensing. View my closed pull requests on GitHub.

Led the development of a custom web scraper Chrome extension, resulting in a 30% reduction in data retrieval time and enhancing overall efficiency. Built custom dashboards, CRUD interfaces, and admin panels that significantly reduced manual workflows for operations, support, and finance teams. Led migration from legacy tools to Retool-based solutions, resulting in a 40-60% reduction in time spent on internal tasks.

Implemented a monitoring system using Terraform and AWS CloudWatch to track RDS DB load, contributing to improved system reliability. Ensured secure handling of project secrets by retrieving them from AWS Parameter Store. Engineered Django APIs with Elasticsearch DSL queries, enhancing search functionality and data retrieval efficiency. Managed Docker for all applications, streamlining deployment processes and ensuring consistent development environments. Led the migration of intensive frontend tasks to Django microservices, improving overall system performance. Orchestrated the migration of Firebase cloud functions to a NestJS backend, resulting in a more scalable and responsive architecture. Implemented TypeScript across all projects, ensuring type safety and code consistency. Managed the CI/CD pipeline, establishing automated workflows in CircleCI for efficient testing and deployment processes.
