About
Afif AlamgirSoftware engineer

I'm a software engineer building production SaaS platforms and AI automation. Most of my work is integration-heavy product engineering on Next.js, Node.js, Supabase and serverless infrastructure.
The work spans multi-tenant SaaS apps, CRM and marketing-automation pipelines, analytics dashboards, Stripe billing and AI content tools, with integrations across Meta APIs, Google services, OpenAI, Anthropic and Gemini.
I care about performance, reliability and keeping API costs low, which in practice means webhook-driven systems, background jobs and careful multi-tenant database design.
I've published machine-learning research with Springer on binarized neural networks for sign-language recognition, and I'm currently going deeper on distributed systems and cloud-native architecture.
