About
I’m a Senior Software Engineer (Fullstack, Frontend) with 10+ years of experience building production systems across enterprise SaaS, developer tools, complex editors, design systems, and AI-assisted products. My foundation is frontend architecture, complemented by hands-on ownership of Python/FastAPI and Node.js services, APIs, asynchronous workflows, data stores, cloud infrastructure, testing, and CI/CD. At ServiceNow, I built React and TypeScript editor controls and a high-performance TinyMCE @mention/autocomplete platform for enterprise workflows. I created reusable integration patterns, accessible keyboard interactions, undo/redo and focus management, and CI/CD workflows that helped distributed teams ship predictable releases. At BrowserStack, I paired a legacy jQuery-to-React/Next.js modernization with Python/FastAPI and Node.js/Express microservices for debugging, reporting, and operational automation. I designed API-backed workflows using PostgreSQL, Redis, and RabbitMQ for persisted state, caching, and queued diagnostic jobs, with AWS services and CloudWatch-style logging supporting traceability and reliability. More recently, I built Screenplay AI as a full-stack product using Vue 3, TipTap, Python, FastAPI, PostgreSQL, and Gemini API, with versioned documents, prompt context, recoverable AI output, and human-review workflows. I also led LottieFiles Creator engineering across React/TypeScript editor architecture, structured animation state, API and AI-service integration, timeline tooling, and reliable preview/apply/recovery flows. I stay hands-on while shaping architecture, making cross-stack tradeoffs, improving engineering quality, mentoring engineers, and aligning product, design, frontend, backend, and platform decisions. Core areas: React, TypeScript, JavaScript, Python, FastAPI, Node.js, REST APIs, microservices, PostgreSQL, Redis, RabbitMQ, AWS, CI/CD, frontend architecture, web performance, accessibility, and AI product UX. Open to relocating across India, including Bengaluru, Pune, and Hyderabad, and available for remote opportunities globally. Portfolio: https://hakimudd.in GitHub: https://github.com/onehanddev
