Message

At Wedfluencer, I build and maintain REST APIs supporting 2,000+ users, and developed real-time vendor-client messaging with WebSockets and Socket.io.

I’ve optimized MongoDB schemas, implemented JWT authentication with role-based access control, and integrated Stripe payments and SendGrid emails. I also managed AWS Lambda, S3, and CloudFront, cutting infrastructure costs by 25%.

Previously, I led backend development at SGI and delivered systems for client projects at Higlax Solutions. I also built backend features for Taskimation, an AI-driven WhatsApp sales automation platform, and designed the backend for Astro Lab Meeting Maker, an AI-powered LinkedIn outreach SaaS.
