Digital systems for brands that verify their work.
I'm Sayad Md Bayezid Hosan — I design and build the web platforms, SEO systems, and marketing infrastructure behind SmartGen, SmartLeadGen, and a growing list of client work. Every claim on this site is checkable.
What I build, on retainer or by project.
Web platforms
Full-stack builds on Cloudflare Workers + D1 — dashboards, SaaS tools, and client sites that stay fast under real traffic.
02SEO systems
Technical, on-page, and local SEO built as a repeatable system — not a one-time audit that goes stale in a quarter.
03Marketing infrastructure
Pixel and conversion tracking, lead systems, and the analytics layer that tells you which of it is actually working.
04Product builds
From idea to shipped tool — the same process behind SmartGen's 120+ utilities and SmartLeadGen's lead engine.
Built, shipped, and still running.
SmartGen
120+ free web utilities plus a full digital-marketing curriculum, built and maintained solo.
SmartLeadGen
Finds businesses with a weak online presence via Google Places, scores the opportunity, and hands agencies a ready outreach list.
GenZ Frontier
An early-stage venture in progress — details land here as it comes together.
What it's like to work together.
Anyone can claim a résumé.
Not everyone can link it.
Every platform I work from — PyPI, GitHub, ORCID, Stack Overflow, LinkedIn, Crunchbase — is listed and checkable in one place. No stock photos, no borrowed case studies.
