I build reliable production systems that connect third-party platforms, automate complex web workflows, and transform data into structured, usable outputs. For projects like this, I bring strong end-to-end ownership—from understanding business requirements and designing the architecture to implementing, testing, deploying, and documenting the solution. I’m comfortable working with HubSpot APIs, OAuth authentication, CRM extensions, file uploads, timeline activities, and custom backend services. I have strong experience with Playwright/Puppeteer-based automation and understand the challenges of automating modern JavaScript applications. I focus on robust selectors, explicit wait conditions, isolated browser contexts, pagination handling, error recovery, and deterministic screenshot/PDF generation rather than fragile timing-based scripts. My strengths are following like these: -Full-stack architecture: Design clean communication between HubSpot, backend services, browser automation, and reporting components. -HubSpot integration: Implement OAuth, CRM record interactions, custom actions/extensions, file uploads, and timeline associations. Browser automation: Build reliable Playwright workflows for navigation, form interaction, dynamic content, pagination, data extraction, and visual capture. -Visual accuracy: Use controlled browser environments and screenshot-based workflows to preserve the exact rendered appearance of reports. -Performance: Optimize the workflow to meet strict execution targets such as completing a requested job within two minutes. -Reliability: Implement validation, retries, timeouts, structured logging, and meaningful failure reporting. -Security: Protect OAuth credentials and sensitive data while minimizing persistence and unnecessary logging. -Deployment: Provide Dockerized, documented cloud deployment with configuration and troubleshooting guidance. I work independently, communicate proactively, and deliver maintainable source code with clear documentation and a practical deployment walkthrough. less -
