A project template for deploying your Python application via FastAPI and NGINX in a Docker container

As software developers, we develop tools as stand-alone applications or as part of a larger product. Often, these tools can be useful in other applications too, whether they are small, such as automatic styling of company documents, or large — in fact, the template is based on our work for the Science Based Target Initiative temperature scoring tool. Eventually, odds are that you would like to integrate your application into a product, a process, or another application.

At the same time, we do not always know in advance how or where our application will be used, and the target application…

The Black–Litterman method is widely used in the investment management industry to incorporate views in investment portfolios. The method applies when views are expressed as expected returns over the horizon for which allocation decisions are made, i.e., the investment horizon.

In practice, the investor’s views are typically formulated for the near future while the investor’s investment horizon is much longer. To incorporate such views, we developed the time-dependent Black–Litterman method and show that, in a time-dependent setting, a distinction should be made between unconditional and conditional views.

Furthermore, we have demonstrate its use for buy and hold investors. Also, we show that the investor’s views have a plausible impact on resulting allocation decisions.

Enabling asset managers of housing associations to create their own machine learning models to assist them with their decision making

Artificial Intelligence (AI) is increasingly used in many domains nowadays. We see data used as input for such models becoming a precious commodity for our clients. With the right tools data can be transformed in valuable insights supporting decision making processes. At Tech Labs we put significant effort into enhancing traditional econometric models on its accuracy while retaining the economic interpretability and exploring innovative ways the make use of proprietary and public data available. In this article we show by example how Dutch housing associations can monetize their data with valuable insights on strategic level. We build a prototype called…

This year’s Ethereum Community Conference took place in Paris, in the beautiful building of Conservatoire National des Arts et Métiers. There were 120+ speakers, 800+ attendees, 4 days, 5 conference halls streaming live in parallel and it was only the 2nd edition! The focus of the conference was on 8 tracks: Data, Privacy, Security, EVM, Identity, Compliance, Dapps and a General path. A ninth track brought lighting presentations on innovative projects under development and various workshops, such as deploying an application with Iexec, introduction to scuttlebutt, next generation EVM, Remixbrowser IDE, consensus testing, game theory introduction, Web3.py …

Nudging autonomous investment decision making for smart contract powered asset management

Dr. Nudge — Created at the Blockchaingers Hackathon 2018

Just like last year, an Ortec Finance Tech Labs team participated at the Blockchaingers Hackathon 2018. Again a very well-organized mind blowing event where 700 pioneers across 63 teams competed with each other within 7 tracks of global challenges. In our track, the future of pensions, nine teams were present. A nice mix between cooperate, student and start-up teams.

As of April 1 Joris Cramwinckel will start his PhD research at the Finance Group at the University of Amsterdam. The PhD project will focus on blockchain applications for pensions. The research will be interdisciplinary, mainly Finance and Computer Science, contributing to the feasibility of disintermediated pension plans. Prof. dr. Marc Francke (UvA) will be promotor, Dr. Andreas Peter (UTwente) copromotor and Dr. Maarten Everts (UTwente) co-supervisor. In addition, Prof. dr. Jaco van de Pol (UTwente) will fulfill an advisory role.

Technical innovations are currently fueling financial disintermediation. Where artificial intelligence has already gained ground in several finance domains like…

Michelle is writing her thesis at Tech Labs about chatbots that are embedded inside a web application. She will even create her own chatbot to support financial planners.

Background information — chatbots

Over the last few years there has been a significant rise in the use of conversational chatbots [1]. Today, we find chatbots everywhere: in the messenger app of Facebook, in Slack, HipChat, WhatsApp, at company websites etc. The main purpose of most of these chatbots is to take over some of the work activities of a support professional. In general the chatbot will answer standard questions that are normally answered by a support professional. …

With conversational interfaces we have finally found a way to improve upon the old point & click paradigm, but how can such an interface be developed?

At Tech Labs we are looking into and working on several possibilities, one of them is Alexa, by Amazon. What started as a Hackathon project is becoming a much more important focus for our research. After creating several skills we started looking at ways to share the knowledge about creating skills for Alexa, the most easily accessible way is through a workshop we created and open-sourced on Github that you can sign up for here.


Looking for new innovative methods to improve UX is, among Blockchain, AI and Software Technologies one of the main pillars of Tech Labs. Mainly because…

The role of property valuations

Property valuations play an important role in many applications. The Valuation of Immovable Property Act (Wet Waardering Onroerende Zaken, WOZ), requires annual valuation of properties, in order to use this value as input for local property taxes and national income and wealth taxes. Property valuation is also important for mortgage applications and for measuring the performance of a real estate portfolio.

Before a property is sold, we cannot know its price. And since the real estate market is not liquid, we cannot simply use past transaction prices. Hence automated valuation models using statistical methods to estimate the market value are…
