I'm a Senior Software Engineer at Contentstack with 6+ years building developer platforms, SDKs, micro-frontends and marketplace integrations at scale.

• 🏗️ Founding member of the Developer Hub & Marketplace micro-frontend rebuild — a platform serving 100,000+ daily active users
• ⚡ Cut application startup from 13s → 150ms through shared dependency resolution and host initialization, not code splitting alone
• 🧰 Owned the App SDK — the integration contract every third-party app on the platform is built against
• 🌐 Maintained 14 reference starter websites across React, Next.js, Angular, Vue, Nuxt, Astro, SvelteKit and Gatsby — one accepted into a major framework vendor's official examples collection
• 🔐 Designed a secure API proxy so marketplace apps reach third-party APIs without credentials ever touching the browser
• 🧪 Built end-to-end testing for sandboxed iframe apps from scratch — no existing pattern for it
• 🛰️ Led the ecosystem rollout across 5 regions and 3 cloud providers
• 👨‍🏫 Mentor and code reviewer — 891 pull requests reviewed
• 🔗 Portfolio: amitkanswal.github.io

• 🏗️ Founding member of the Developer Hub & Marketplace MFE initiative — carried it from early architecture through general availability, with independent deployments per surface and a separate release track so the migration never blocked delivery
• 🧰 Owned the App SDK end to end — design, implementation, documentation, releases and developer support, adding capability across four escalating phases without breaking a single existing integration
• 🔌 Built a general-purpose API method letting sandboxed apps reach the platform's full management API, replacing a narrow fixed allow-list
• 📋 Turned an app requirement into a platform capability — an editorial workflow board needed advanced content search that didn't exist, so I added it to the SDK and other teams adopted it
• 🛡️ Secure API proxy handling 10,000+ calls per day with validation and transformation
• 🌍 5 regions across 3 cloud providers, converting 35+ components from hardcoded endpoints to regional resolution
• 📦 ~25 formal production releases, one bundling 12 interdependent components at distinct versions
• 🐞 563 bugs owned and fixed, many surfaced by testing infrastructure I built
• 🥇 Runner-up, Contentstack Hackathon — prototype later shipped as a product feature
• ⭐ Above & Beyond Award ×4 for consistent platform impact

Happy to talk about developer platforms, SDK design and micro-frontend architecture:

• 🧱 SDK & Platform Architecture — stable contracts other teams build on
• ⚛️ Micro-Frontends — Module Federation, independent deployment, migration strategy
• 🧪 Test Automation — Playwright, sandboxed environments, release gating
• 🧩 Developer Experience — internal tooling, documentation, self-service setup
• 🌐 Multi-region Platforms — data residency, regional rollout, release coordination
