Career
Experience
Feb 2022 – Now
AEM Developer / Senior Backend Engineer
Abbott
Joined in Feb 2022 on an AEM 6.3 product platform and led the migration path through AEM 6.5 to AEM as a Cloud Service.
- Led the AEM 6.3 → 6.5 migration in 2023 and the AEM 6.5 → Cloud Service migration in 2024.
- Refactored components and templates, authored Sling Models and HTL, and built shared component libraries for AEM teams.
- Improved developer workflows with CI integration, performance tuning, observability, and migration runbooks.
- Served as technical lead in 2025 on a headless AEM + Next.js commerce delivery, coordinating frontend and backend teams.
Jun 2019 – Feb 2022
AEM Developer
SLP Technologies Private Limited
Delivered AEM 6.3 component and template development with a strong focus on reusable patterns and authoring experience.
- Built AEM 6.3 components, templates, Sling Models, HTL (Sightly), and content.xml authoring.
- Designed authoring dialogs and multifield experiences for rich editor interactions.
- Implemented template structures, policies, and client libraries for consistent rendering across author and publish environments.
- Integrated AEM authoring workflows with backend/frontend release handoff and performance validation.
2024 – 2025
Engineering Projects & Hackathons
Internal / Side projects
Delivered tools and processes that reduced deployment time and standardized AEM component development.
- Built a frontend-only deployment pipeline during a hackathon, reducing AEM full-stack deployment time from ~3–4 hours to ~20 minutes by deploying only changed frontend assets.
- Won two internal hackathon prizes for deployment automation and developer productivity improvements.
- Created a component generator tool that scaffolds content.xml, Sling Models, HTL, and JUnit boilerplate from a single form.
- Standardized component creation and reduced manual development overhead across projects.
