Marc Mintel, freelance web developer

Ambitious web projects require proven technical craftsmanship.

01Hello

I am Marc.

I have been engineering for the web for 15 years: first in digital agencies, later as a senior developer in product teams, and now as an independent software engineer.

My primary focus is on what users see and interact with: thoughtful design and intuitive interfaces. Having deep expertise in backend architecture and APIs as well, I deliver complete, production-ready applications from a single source.

You work directly with me – whether you lead an established product team or are launching your first digital initiative.

The path so far

  1. 2011Started in the webApprenticeship
  2. 2014 – 2020AgenciesFrontend developer
  3. 2020 – 2023Product companiesSenior software engineer
  4. TodayIndependentDirect collaboration with clients

First, we clarify your core requirements and architectural goals.

02Services

What are you planning? Tailored engineering for your goals.

Seamless system integration – eliminating manual data entry and routine busywork.

Exporting spreadsheets, retyping entries into CRMs, emailing notifications by hand: I connect your existing software through robust APIs so data flows automatically and your team can focus on high-value work.

What you receive

  • Direct API integrations between your existing business tools
  • Fully automated workflows without manual intervention
  • Targeted AI steps where valuable: document parsing, categorization, summarization
  • Concise system documentation for reliable operation and easy maintenance

The process

Intro call, about 20 minutes1 / 4
YouMeabout 20 minutes

A clear, binding quote before project kickoff.

Send me a brief outline of your project. After a 20-minute intro call, you receive a transparent, written quote. Work only starts once you approve.

Often, the right solution isn't more software – it's connected workflows.

03Process automation

Automate routine workflows. Eliminate errors and manual handoffs.

In many companies, team members spend hours moving data between tools: exporting files, copy-pasting records, emailing updates. Smart automation connects these tools via APIs so data flows in the background. Three typical examples:

running

When an order is placed in the shop, the invoice, CRM record and confirmation email are generated automatically.

Manual

Manual: inspect the order, generate the invoice, update the CRM, and email the customer.

Automated

Automated: the order triggers every downstream step – your team simply monitors the result.

Worth automating when

  • Identical tasks repeat daily or weekly
  • Data is manually moved between different software tools
  • Delays or mistakes occur due to monotonous routine work

What stays with your team

  • Strategic decisions and nuanced exceptions
  • High-touch customer relationships and advisory
  • Final sign-off on ambiguous cases

What I need from you

  • Access to the software tools and their APIs
  • Insights into the current workflow from the people running it
  • Real-world test data for validation

Or a high-stakes presentation that needs to leave a lasting impression.

04Web presentations

A presentation as a link. Not as an attachment.

Most presentations are still static slide decks sent as bulky email attachments. I build presentations as interactive web experiences: accessible in any browser, fully responsive on any device, and capable of live interactions slides could never support.

Flawless on every screen

Whether on a 4K projector, laptop, or smartphone: content reflows naturally for optimal readability.

One live link, always up to date

No more circulating outdated attachment versions: edits are instantly live for anyone opening the URL.

Real interactivity over static screenshots

Embed live metrics, working product demos, or clickable prototypes directly into the narrative.

A lasting asset after the meeting

Instead of being lost in inboxes, your presentation remains a high-impact, shareable landing page.

Typical uses

  • Company and product presentations
  • Pitches and proposals sent as a link
  • Reports with dynamic, changing data
  • Display screens at trade fairs and events

When standard slides are sufficient

For a quick internal status update, a PowerPoint or Keynote deck is faster and more pragmatic. A web presentation shines when presenting high-stakes pitches, recurring keynotes, or public-facing company milestones.

The end result: rock-solid software that performs reliably in production.

Answers to common questions before we begin.

06Questions

Good to know before we talk.

I don't have a technical background. Is that an issue?
Not at all. I communicate technical concepts in plain, accessible language. You never need to read code or decipher jargon to make sound business decisions.
How much does a project cost?
It depends on scope and complexity. After a brief intro call, you receive a transparent, itemized quote. Engineering work only begins once you give your explicit sign-off.
Who owns what you build?
You do. Full copyright and intellectual property rights for code, assets, and documentation belong to you – no strings attached.
Who maintains the website after launch?
I do, if you wish. For 89 EUR per month, hosting on secure German servers, security updates, and minor content adjustments via email are covered. No CMS overhead for you. Existing email inboxes remain with your current host.
How do we get in touch?
Best via email or video call. As I work remotely, we schedule meetings to suit your calendar.
