Daniel Miara

There’s a person behind the code.

I’m Daniel Miara. I run 3D Studio Production, established in 2001. My work covers OpenCart shops, payment integrations and apps.

We start with the problem, agree scope and cost, then implement and test the solution.

From 3D design to ecommerce

3D Studio Production was founded in 2001. Its origins in 3D design gave the business its name, before it developed into a studio working on websites, shops and payment integrations.

Today we combine OpenCart expertise with our own products. Shop structure, UX, content, logistics and automation are scoped around how each business works.

Work directly with Daniel

The studio is led by Daniel Miara, founder, developer and ecommerce solution architect. We start by discussing the problem and availability, then agree scope and responsibility for each part of the work.

A project also covers what happens behind the screen: orders, data and the team’s everyday work.

Data and security

Access controls, customer data privacy and payment process requirements.

Hosting and backups

Hosting selection, backup configuration and recovery after an incident.

Shop communications

Mailboxes, contact forms and automated transactional notifications.

Domain and brand

Domain strategy, language versions and preparation for new markets.

After launch

Administration, feature development and an agreed support model, including SLAs.

Ownership and handover

Clear responsibilities, licences, documentation and training within the agreed scope.

My focus: OpenCart and integrations

I have worked with OpenCart since 2010: shop administration, extensions, performance and connecting sales with payments and back-office systems. My integration experience includes PayU, Tpay, Worldpay, First Data, Bambora, Barclaycard and Global Payments.

I do not take on rebuilds based on the Journal theme. I focus on solutions that can be maintained and developed. Availability, administration terms and SLAs are agreed individually after reviewing the task.

We also build our own products

JustPayFor

Payment links, baskets and QR codes. A product developed by 3D Studio Production.

DEFINITELY RECOMMEND! Incredibly fast in action! In a very short time, Daniel fixed the errors in my store, advised on many issues, and performed a number of actions that were messed up by the previous BIG company. Full professionalism, courtesy, and patience with the client. I will turn to him for help without hesitation because I know I will get it!

AgataOgaFacebook review

I recommend Daniel's company to everyone. My store platform was efficiently updated to the latest OC version with many useful add-ons. Thanks also for the updates and fantastic technical support. Whenever there is any problem with OC, I know I can count on professional and quick reaction from Daniel. I recommend!

Sklep Polskiego PrepersaFacebook review

I recommend 3D Studio Production Daniel Miara for professionalism, individual approach to the client, and expert help. Daniel not only analyzed our store for errors but also proposed long-term solutions. He informed us what we can do better and what to pay attention to. The speed of action is really impressive compared to other companies I have dealt with.

Hanna TFacebook review

I wholeheartedly recommend Daniel! We modernized the store together and fixed errors from the previous "company". Excellent contact, all arrangements consulted on an ongoing basis. In two days, we managed to do more than in a month with the previous company!

Tymek GFacebook review

Great service, lightning-fast responses, a product that 100% meets expectations, which is a plugin for Opencart3 that supports Inpost shipping with an interactive map! I recommend.
