Best Full Stack Developer in California for startups and growing brands.
Looking for the best full stack developer in California? I build first versions of web products: sign-in, dashboard and API, plus the marketing site.
How I work with California businesses from Dhaka
California is 13 hours behind Dhaka in summer and 14 in winter. My evening lines up with your 7 am to noon, so you get replies before the workday gets busy and a live call is easy early in the morning.
What California businesses ask me to build
Startups and SaaS
An MVP with sign-in, a dashboard and an API, plus the marketing site that sells it. Wrkbase, my own SaaS, went from idea to launch this way, including an AI agent that acts only after approval.
Direct-to-consumer brands
A custom storefront and order dashboard when a hosted store builder or a plugin stack has stopped fitting how the brand sells.
Creator and media businesses
Membership sites, course platforms and fast content sites. I built the WordPress LMS for Open Alliance Learning, with a dashboard for learners, teachers and assessors.
Projects I've built, with live sites

Tabby
A website relaunch for Tabby: front end, back end, custom plugins and payments, then the full 2.0 rebuild with its SEO kept in place.

Wrkbase
SaaS development from scratch for my own product: I designed and built the software, the AI agent and the website it is sold from.

What to check before you pick a full stack developer in California
- 01
Live projects to click through
Ask for sites you can use, not screenshots. Mine are Tabby, Wrkbase, Open Alliance Learning, each with a case study.
- 02
The admin side, not only the website
Orders, users, stock and reports are where a business spends its day. Ask who builds those screens and who keeps them working.
- 03
One person from design to launch
Fewer hand-offs means fewer misunderstandings. I research competitors, design the UI and UX, then build the frontend and backend myself.
- 04
A reply you can plan around
You get an answer within 24 hours, prices in US dollars, and a written quote before work starts. Websites from $600, web applications from $999, WordPress builds from $300.
Services

Websites and online stores built from scratch: UI/UX, frontend, backend and admin dashboard.

How your project runs, step by step
- Step 01
Study your competitors
I look at what competitors do well and where they leave gaps, before a single screen is drawn.
- Step 02
Design the UI and UX
I design the screens myself, so what you approve is what gets built.
- Step 03
Build frontend to backend
Pages, accounts, orders, payments and the admin dashboard, built as one job.
- Step 04
Launch and look after it
Speed checked on a phone, then backups, monitoring and changes through website care.

Your questions about hiring a full stack developer in California
Ask something else on WhatsAppCan you build an MVP quickly?
Yes, by cutting scope to the one thing users must do. I build that first, properly, so real users can start on it, then add the rest in order. You see working screens every week.
Have you worked with California companies?
Yes. Tabby, an AI bookkeeping company in the US, hired me to build its v2.0 website ahead of an event in San Francisco, and I have worked with them for two years since.
How do I reach you across a 13-hour difference?
I work an evening shift in Dhaka that covers your 7 am to noon Pacific. Messages sent in your afternoon are answered by the next morning, and live calls are best before 11 am your time.
Do you use AI in the products you build?
Where it helps. Wrkbase includes an AI agent that executes approved actions and keeps an activity log, and I have built AI demo plugins for Tabby. I will only add AI where it solves a problem your users have.
