A platform that provides safe, smart bus services for commuting and school runs.

Some of the platform's functionalities are the ability to purchase tickets on any bus route, email and SMS trip reminders, the generation of PDF tickets, an admin panel with different permission levels for general management, route creation, and customer support. It can also create private rides and invite other people to join. There is a driver web app used for tracking and checking passengers' tickets and is integrated with a third-party CRM.

I was present from the beginning of this start-up. I designed the Zeelo system from scratch, created a development plan, and then built the MVP, which they brought to market.

As the platform grew, I continued to maintain and improve it, adding new features.

During my time here, I witnessed Zeelo blossom into a successful company with a large user base. I worked with the growing developer team to improve its scalability using Hexagonal Architecture, Event Sourcing, and CQRS with Symfony.

A presentation and eCommerce website.

Bryant Dental was one of our clients at Kappa London. We were hired to build a new website for their business, improve their web presence, and add eCommerce functionality.

I designed the system and infrastructure, managed the development team, and worked on the back-end side, most notably delivering the required eCommerce functionality through a REST API and developing custom features for the store's administration panel.

The rest of the team worked on design and branding. Their effort was stellar and the website managed to get an honorable mention from Awwwards.

A digital community that facilitates the intergenerational exchange of knowledge, experience, and companionship in a fun and safe way.

The platform matches users based on certain factors, who are then able to schedule an appointment and engage in conversation, either through text, audio, or video.

I was the back-end developer. I designed the system, infrastructure, and the REST API. Together with one other front-end developer and one designer, we built the MVP, which was then launched. We kept maintaining it and adding new features over time.

A platform where any customer can find rated tradespeople and tradespeople can receive live job leads.

Users could register either as customers or as tradespeople on the platform. Customers could post different types of projects they needed doing (e.g., construction projects), and tradespeople would receive notifications on new projects based on their skills, location, and other factors. Tradespeople could then bid on the projects they received and the customer would accept one or more of them. To bid, tradespeople had to buy credits, out of which a certain amount was spent on each bid. The platform also had an administration panel.

I was hired to take over the development of the platform, which was not in great shape and had multiple issues, especially with the notification and bidding system. I was the only developer. I refactored parts of the system and released a safe and stable version.

I continued to maintain the platform and add features.

A platform for providing premium, on-demand bicycle repair services in London.

It allowed users to create an account, save their bikes, and purchase one-off repair services or subscriptions that offered them regular monthly/yearly checks and repairs. The system also had an admin panel and was integrated with the Lightspeed POS system, which they used in their repair shop. The platform also had an administration platform.

I was the lead and back-end developer. I designed the system and together with another front-end developer, built the platform and delivered it to the client.

A resume builder app.

The app allowed users to choose from multiple resume templates and easily add in their own information. Users could then download a PDF version of their resume. They could also manage multiple versions of their resumes.

I was the only developer. I designed the system and infrastructure and built the app. I continued to maintain it and add features.

An online store where we sold our own custom Expression Engine modules.

Having worked with Expression Engine a lot, one of my friends and I decided to build custom modules for the CMS, polish others we had already built, and sell them online. Thus, we created MK Labs. We sold some copies of the modules and provided support and fixes for some time. Expression Engine evolved into newer versions. We lacked the time to upgrade our modules, and eventually, we closed the store.

I worked on developing the modules and conducted another friend that provided a helping hand. I also worked on building the MK Labs store.
