Backend engineer at Voushify building verified-recommendation SaaS billing, authentication, and production services.

Bangladesh

Message

At Voushify, I lead backend development for a verified-recommendation SaaS platform, owning Authentication, Profile, and Billing services from design through production. I built Stripe billing with idempotent webhook processing, atomic credit transactions, and entitlements that gate paid features.

At GraphLogic Inc, I built the backend of a graph-based modeling platform with Java 21 and Spring Boot 3. I integrated Spring AI embeddings with a Neo4j vector index for RAG over users' graph data, alongside an asynchronous AI-enrichment pipeline.

At Codemen, I developed Go/gRPC microservices for seven products on Brankas' open-finance platform. The work covered payment and banking integrations, OAuth2/OIDC identity services, and infrastructure deployed with Kubernetes and Terraform.

At Mercor Intelligence, I authored 16 merged SWE-bench-style tasks for AI coding agents, with Dockerized environments, test patches, and grading rubrics. Earlier, I built Laravel applications and .NET property, mortgage, and digital wallet products.
