Chief Consulting Architect - Node, React, AWS, MySQL
Over-all responsible for tech - reporting to the founder CEO for a major Indian eComm portal.
Dec, 2023 - Ongoing
I guide the in-house engineering team through tech implementation of the business requirements. I also identify & prioritize tech-debt. Some examples:
- Improve product reliability via error tracking, request tracing & regression test coverage.
- Scale the APIs by improving synchronized cache invalidation to better leverage caching.
Lead Consultant - Strapi v4, Next.js v13 website
Handling business logic implementation, reliability, performance
Oct, 2023 - Ongoing
As the senior-most individual contributor within the team, I'm responsible for:
- Solving scalability, security, performance, reliability issues.
- Coding the core-business-logic aspects within the backend APIs & cron jobs.
- Interfacing with various teams (business, users, support, devops) to ensure adequate requirements implementation.
Gatsby.js => Next.js 13 (App router) migration
Mentored migrating a frontend from Gatsby v5 to Next.js v13
Oct, 2023 - Nov, 2023
While the in-house frontend team executed the actual migration, I provided Next.js v13 specific guidance:
- Setup data fetching, ISR, cache invalidation and content preview mechanisms in-line with the content team's requirements.
- Provided a path to upgrade the existing pages using Chakra UI to React Server Components (Next.js App router).
Backend Cloud Migration (AWS => Azure)
Migrated a Strapi setup from AWS to Azure services
Aug, 2023 - Sep, 2023
This Strapi setup (in production for 1.5 years) leveraged various AWS services (S3, Cloudfront, SQS, SES). The project involved:
- Modifying code to leverage the equivalent Azure services (while handling Cloud provider specific differences).
- Migrating the existing data & files from AWS to Azure.
- Performing the storage migration (Terrabytes worth of data) with a minimal downtime via feature-flag driven development.
Strapi Upgrade
Undertook v3 => v4 upgrade for a complicated CMS setup
May, 2023 - July, 2023
This Strapi upgrade was more complicated than the ones I executed earlier:
- The setup (in use since 2019) had many data inconsistencies (orphan records, foreign key violations) needing pre & post data-processing.
- The large number of dynamic zones & relationships transated ~60 collection types into ~1k postgres tables being migrated.
- The global all-remote team with members working in many timezones demanded prompt communication for a timely execution.
Angular Frontend Optimizations
Identified optimizations & mentored the in-house team on implementation
Jan, 2023 - Feb, 2023
Having worked with on this eComm org's site speed & scalability earlier, their CTO tasked me to identify & mentor the execution of industry best practices wrt. their Angular frontend:
- Identified the gaps in aspects like PWA push notifications, Angular universal implementation, in-the-wild error tracking among others.
- Mentored the org's in-house frontend team to implement the identified gaps.
Strapi Customizations
Undertook data migration & customization for an Enterprise CMS setup
Nov, 2022 - Aug, 2023
Being the primary go-to backend person on this project, here's a few major items I have implemented so far:
- Undertook data migration to move from an in-house CMS to Strapi.
- Implemented a custom access-control for Strapi Rest APIs to securely serve sensitive data.
- Implemented single sign-on, custom plugins, integration with self-hosted search, etc.
Core web vitals Optimization
Improved site speed for a Wordpress based marketing site
Oct, 2022 - Nov, 2022
Other than improving the site speed, this engagement involved reviewing the hosting infrastructure & educating the team on site speed aspects:
- Introduced the Cloudflare CDN & Wordpress full-page caching to improve the server response speed.
- Configured image optimization + caching for faster image loading.
CMS Framework Selection
Undertook a proof-of-concept to identify suitable CMS framework
Nov, 2022 - Dec, 2022
Having worked on multiple initiatives for this B2C org, I was tasked to provide tech inputs wrt. selecting JS based headless CMS framework:
- Gathered must-have & good-to-have requirements from various stakeholders.
- Initial evaluation led us to Directus & Strapi for a more detailed PoC.
- Undertook a PoC implementation of the must-have requirements & provided the tech feedback.
