Best Full Stack Developer in New York for custom websites and web apps.
Looking for the best full stack developer in New York? I cover what a small agency would: competitor research, UI/UX, frontend, backend and a dashboard.
How I work with New York businesses from Dhaka
New York is 10 hours behind Dhaka in summer and 11 in winter. My 8 pm is your 10 am, so we can meet inside your normal workday and I reply in writing before you start the next one.
What New York businesses ask me to build
Fintech and payments
I wrote the payment gateway plugin and merchant onboarding flow for Moneybag, a licensed payment gateway, with OTP sign-in and CRM integration. Money flows need exact rules, which is why the logic belongs in code written for them.
Agencies and studios
Your design, built under your name, or an extra developer for a client project. White-label work is a service I offer separately.
Professional services
A credible, fast website for a firm, with enquiry forms, a client area when you need one, and pages written so they can rank.
Projects I've built, with live sites
Pick a project to see the result and the live site.
Moneybag
A custom WordPress plugin and website for Moneybag, a licensed payment gateway, built for security and speed.
60%less time to onboard a merchant
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.
90+Core Web Vitals at launch
Mayabee
A custom ecommerce website for Mayabee, a handbag and jewellery shop in Dhaka: English and Bangla storefront, an admin dashboard for orders, cash on delivery, stock and reports.

What to check before you pick a full stack developer in New York
- 01
Live projects to click through
Ask for sites you can use, not screenshots. Mine are Moneybag, Tabby, Mayabee, 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
Custom website development
Websites and online stores built from scratch: UI/UX, frontend, backend and admin dashboard.
Web application development
Customer portals, internal tools and SaaS: sign-in, roles, dashboards and APIs.
WordPress development
Themes, plugins, stores and payments, built as one job.
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.
