Hello, I'm Tamim Hasan · tamimlabs
Self-taught engineer by obsession. I build custom websites, web applications, and automation for real businesses — from scratch, in the open, and owned entirely by you. No templates, no page-builders, no locked doors.
I don't do templates — on principle You talk to the person who writes the code If you don't need custom work, I'll say so
Working with me means
Since you're hiring a person: the working software is public — judge me before you trust me.

the work is public, so you can check it yourself
Unlike most developers, my working software is public — the code, the real-time demos, and the case study are all linkable from this page. Nothing here is invented: no fake clients, no made-up results, no stock testimonials.
What I build
Every service below is delivered as original software — designed around your requirements, documented, and built to last. Not a plugin. Not a theme.
Business websites and landing pages built from scratch to turn visitors into enquiries and sales — not assembled from a template.
Your current site, rebuilt from the ground up: faster, mobile-first, easier for customers to find you on Google, and a look that matches the business you are today.
Storefronts built as real software — product catalog, checkout, payments, and order management that don't fight your customers.
The behind-the-scenes work that helps the right customers find you — structure, speed, and data the search engines actually read.
A site that loads before your visitors give up. I target real Core Web Vitals, and you get the before-and-after numbers — not guesses.
Bookings, leads, follow-ups, and notifications handled automatically — the repetitive work gets removed, not just moved around.
Dashboards, customer portals, booking systems — an application built around how your business actually runs, not how a template thinks it does.
Not sure what your business needs?
Describe your problem in plain words — I'll tell you honestly what's worth building, and what isn't.
Describe your problemA note on honesty: custom development isn't always the right answer. If a simple brochure site on a standard platform genuinely fits your need, I'll tell you so instead of over-engineering for the sale. Custom is the right choice when you need it to work differently, faster, or better than what a template can do.

This page itself is the same idea, built for real — this section is a width-based approximation; production builds are tested on actual phones and tablets.
A slow page costs you visitors and your Google ranking — a fast one keeps both. Two routes to build a website, and what each one costs your customers:
Things your visitor's phone must download before the page can appear
a handful18 files
Total weight your visitor carries before seeing anything
light~180 KB
Slider, plugin & tracker baggage that ships regardless of need
skippedonly what the page needs
A custom build ships only what your page actually needs — semantic structure first, JavaScript only where it earns its place.
Illustrative comparison of the two approaches — not a promise about any specific site. On a real project, your actual numbers get measured and shared, before and after.
Hand-coded · running right here
18 tailor-made layouts rolling past — a different site for every business you can imagine, each hand-built and styled to fit that trade. Whatever you run, there's a version of it here.
This is what I build for clients. One of these design-languages is yours — tailored to your business.
Let's build yoursBusiness problem → custom solution
Open a problem that sounds familiar. Every one of these is something custom software was built to fix — not by installing a plugin, but by engineering the right system.
A rebuild from the ground up — modern custom-coded architecture, a design that works on today's phones, and your content migrated properly.
A performance-focused optimization or rebuild — lean code, optimized assets, and measurements against real Core Web Vitals instead of guesses.
A custom quote-request system — a form that captures exactly the details you need and routes straight into your inbox or CRM.
A booking interface built around your availability and services, wired to confirmations, reminders, and your calendar.
An automated workflow — requests get captured, answered, routed, and followed up without a person doing every step by hand.
A custom web application — accounts, orders, documents, or bookings, tailored to how your customers actually use it.
Custom development exists for exactly this — if no off-the-shelf tool fits your workflow, that's the workflow worth building.

Not mockups or case-study PDFs: live things you can open, plus public code you can inspect — including two full systems built for Google hackathons.

Curious how a project like this actually gets built — and what that means for yours?
See how I workA real project, shown end to end
Instead of describing my process, here's a completed project: an autonomous work system built solo for Google's All Things Agentic hackathon. Every claim below is public and verifiable — and this is the standard any project of yours would be held to.
The problem it solves
A business has repetitive, low-judgment work that still takes real human hours — triaging inboxes, watching channels, chasing updates. Most software helps one step at a time and stalls the moment anything fails, so a person has to babysit it.
The system I built
Given one sentence of intent, it plans the work, executes it step by step, checks its own results, corrects course, and asks a human before anything risky — all of it visible on a live dashboard while it runs. I designed, built, tested, and documented it alone, the way I'd run your project.
Built with
The full stack is documented in the public repo — the point here is the standard, not the acronyms.
The standard behind it — and what it means for your project
Planned before it acts
Given one goal, the system maps out a plan, then works through it one step at a time — reading real results before choosing the next step. No blind guessing.
Fails openly, then corrects
When a step goes wrong, it says so and adjusts rather than stalling — the same honest, fix-it mentality you'd want from a team you hire.
You can watch it work
Every step streams to a live dashboard. Nothing runs invisibly — on your own project, you'd see the progress, the decisions, and the trade-offs.
A human approves the risky parts
Actions that carry risk pause and ask for a person's sign-off — from a phone if needed. Safety gates, not sleepwalking.
It learns as it works
Finished jobs become proven, reusable procedures that get better over time — so it doesn't repeat past mistakes.
Costs nothing when idle
Built on cloud infrastructure that scales to zero — no wasted spend between jobs. That's how I think about your budget too.
Rigor, in numbers you can check
automated checks in the shipped code — bugs caught before they reach anyone

platforms it can watch and act on — GitHub, Slack, Jira, email, and more

Live dashboard traces every decision — nothing runs invisibly
Risky actions pause for human approval, one tap from a phone
Design, code, tests, and docs all produced by one accountable person
How a finished project is handed over
You own it
Clean, documented code and no platform lock-in — move hosts, extend it, or hand it to any developer later.
It's tested
Automated checks protect it and performance is measured — not promised.
No handoffs
One accountable developer from the first call to long after launch.
Explained in plain English
You get a walkthrough of what you own and how to use it — not a file dump.
Verify it yourself
The complete project is public: the repository, the demo video, and the hackathon entry. I won't invent revenue lift or user counts — the engineering, the tests, and the docs are the evidence, and they're all yours to check.
The kind of software your business runs on deserves this standard too.
Tell me the workflow that's eating your team's time, and we'll design the system that removes it.
Start this conversationWhy custom code wins
Everything on this page was built this way: no templates, no page builders, no rented website software. That's not a style preference — it's the reason the results are dependable and the site stays yours.
An honest caveat
Sometimes a lean template, WordPress, or even no website is genuinely the right call — a small static page on a one-pager subscription can be perfect. When that's true for you, I'll say so. What I won't do is sell you complexity you don't need.
A template drags along a framework, sliders, and plugins for features you'll never open. Custom code ships only what your site actually needs.
Semantic HTML, schema.org markup, metadata, sitemaps, robots rules, and fast first loads aren't bolted on afterward — they're the foundation.
Speed and ranking claims get verified: Core Web Vitals run against the actual build, before and after — and the numbers are shared honestly.
The design system is tied to your business — content, calls to action, and customer flows — instead of reskinned around a template's assumptions.
Clean, documented code you can move to any host, extend, or hand to any other developer. You're not renting a brew that's been brewed weird.
Automation, booking, dashboards, integrations — when your first custom build is done, adding systems is one more layer, not a migration.
A website built this way is a business asset — not a subscription you hope keeps working.

I'm Tamim Hasan. My second brain has always been engineering. I taught myself to code, then taught myself to build like a professional: quiet Sunday mornings in the library writing a 50-level JavaScript game, weekends plumbing event streams through Cloud Run for a hackathon build, and long nights turning a download-manager idea into Rust that actually feels fast.
I think in systems and trade-offs. Measure first, change second. If I wouldn't trust the number, I don't print it on a website.
I work directly with owners — no account managers, no ticket queues. You get the person who wrote the code.

In a word, the people I've worked with would probably describe me as blunt — in the sense that you always know where you stand. Ask for an opinion and you'll get one.

02
Design, architecture, and code together — you see working pages early and often, not one big reveal.
03
Real device testing, accessibility, Core Web Vitals measured and shared.
