FELLER.

Landing pages that sell — and AI that does the busywork.

I design conversion-focused landing pages for small businesses, and build the AI chatbots and automations that answer customers, follow up, and save you hours every week.

Selected work

Five sample projects, built end-to-end the same way I build for clients — same process, same quality bar. Each one is labeled honestly: they are concept pieces for fictional businesses, made to show you exactly what you would receive.

PureNest Cleaning Co. landing page: headline 'Come home to a house that's actually clean', booking button and price estimator

PureNest Cleaning Co.

Concept project

Landing page · Home services

A booking-first page for a home-cleaning company. The whole layout pushes one action — get a price and book — with trust signals (bonded & insured, re-clean guarantee, verified reviews) placed exactly where a hesitant visitor looks for them.

  • Instant price estimator — quote before booking, no phone call needed
  • Flat-pricing and guarantee sections that remove booking hesitation
  • Mobile-first layout with a sticky “Book a clean” action

Ember and Oak coffee house landing page: headline 'Slow mornings, serious coffee', order-ahead button and café photography

Ember & Oak Coffee House

Concept project

Landing page · Café / hospitality

A warm, editorial page for a specialty coffee house. Atmosphere does the selling — story, craft and today’s pour up front — while practical details (open hours, order-ahead, work-friendly seating) answer the questions that decide a visit.

  • “Order Ahead” path for regulars, menu and story for first-timers
  • Daily-pour feature card that gives regulars a reason to return
  • Visit essentials — hours, beans, Wi-Fi — without a separate FAQ hunt

Serene Dental Studio website with an AI chat assistant in the corner that answers pricing and booking questions

Serene Dental Studio

Concept demo

AI chatbot · Dental clinic

A clinic website with an AI assistant that books patients while the front desk is busy — or closed. It answers price and treatment questions in a calm, plain tone, then books the appointment in under a minute, right in the chat.

  • Trained on the clinic’s services, prices and booking rules
  • Answers after-hours questions instead of losing the patient
  • Hands off to a human whenever a question needs one

Northwind Goods automation console: one order triggers an AI thank-you email, inventory update and owner notification

Northwind Goods

Concept demo

Workflow automation · Online store

An order workflow for an online store: one order comes in, everything else happens by itself. A working demo console walks through each automated step — roughly six minutes of manual busywork removed from every single order.

  • AI-written, personalised thank-you email per order — not a canned template
  • Inventory updated automatically the moment payment clears
  • Instant owner notification, with a full activity log for peace of mind

Audit cover page: AI Opportunity Audit for Peakform Fitness Studio, prepared by FELLER
Audit page: prioritised AI use cases for the fitness studio
Audit page: ready-to-use example prompts written for the business

AI Opportunity Audit — Peakform Fitness Studio

Sample report

AI audit · Written report · Fitness studio (fictional client)

A six-page written audit that finds where AI actually pays off in a small business. For Peakform, the verdict: not a marketing problem — a response-time problem. The report maps each leak (unanswered night-time questions, no-shows never followed up, trainers retyping the same answers) to a specific, buildable fix, rated by impact and effort.

  • Four focused AI systems, each tied to a real cost in hours or lost bookings
  • Two complete, ready-to-use prompts so you can judge quality before buying more
  • A plain-language roadmap — no new software the team must learn from scratch

How we’ll work together

Simple, written, and asynchronous — you always know what’s happening and what comes next.

1

Brief

You tell me about your business and the one result the project must produce. I reply with scope, price and delivery date — in writing, before anything starts.

2

Build

I design and build the full deliverable, then send you a preview link or file you can open and click through — not a screenshot and a promise.

3

Revisions

You comment, I revise. Every package includes revision rounds, and I’ll tell you honestly if a request would hurt the result more than help it.

4

Delivery

You receive the final files plus a short handover note: what was built, how to use it, and how to reach me if something needs adjusting.

AI-assisted, human-directed. I use AI tools (Claude, Gemini) to work faster, but every page, prompt and workflow is directed, checked and finished by me. You’re hiring a person who is accountable for the result — the tools are just how I deliver it quickly.

About

I’m Darmawan, a designer and builder based in Bekasi, Indonesia, working under the studio name FELLER. My focus is narrow on purpose: pages that turn visitors into customers, and small AI systems that give owners their evenings back.

My background is hands-on technology — years of Android work and running my own self-hosted automation — which is why my chatbots and workflows are built to survive real customers, not just demos. The samples above are concept pieces; my process, standards and communication are exactly what you see here.

Questions, answered straight

Are these real client projects?

Not yet — and I won’t pretend otherwise. Each piece is a concept project I designed and built for a fictional business, using the same process and deliverables a paying client receives. Judge the work itself: open the samples, read the audit, and decide if that quality is what you want for your business.

What do you need from me to start?

Your business name, what you sell, who it’s for, and the one action you want visitors or the automation to produce. Text and photos you already have are plenty — if something’s missing, I’ll say so in the brief and suggest the simplest fix.

How do we communicate across time zones?

In writing, asynchronously — messages on Contra or Fiverr, with a reply within one business day. I’m on GMT+7 (Indonesia) and keep ±2 hours of flexibility for anything that truly needs a live exchange. Written communication also means you get a clear record of every decision.

How does payment work?

Through the platform — Contra or Fiverr — at the fixed package price we agree in the brief. The platform holds your payment until you’ve reviewed and approved the delivery, so there’s no risk in trying a first, small project.

Tell me what you’re building.

A page that needs to sell, an inbox that never sleeps, a task you’re tired of doing by hand — send a short message about any of them. You’ll get a written reply with scope, price and a delivery date, usually within one business day.
