I offer back-end, Linux, iOS and macOS app development for your project.

I know what makes a project successful

I have been working in the areas of mobile, IoT, space systems, networking and data. A common theme for all these fields is that quality is critical.

I have been leading multi-national technology projects and I have always done hands-on development to keep my skills fresh.

I can help you with the following topics.

Develop a back-end solution.
Help you to get most out of using AWS cloud.
Develop a high-performance and native iOS app.
Develop a high-performance and native macOS app.
Help you to get most out of the App Store.

Tommi Kivimäki

These are the technologies that I use almost every day.

Server side Swift

High performance and small memory footpring equals less money on servers.
Safe & statistically typed language improves quality.
Close to C-like performance.

Node.js

The most popular back-end solution.
Great fit for AWS Lambda.
Plenty of available libraries.

Swift on iOS and macOS

The best performance using native development tools for the platforms.
Gives the best end user experience.
Easy and affordable to maintain apps.

AWS cloud

Services that I use most frequently include IAM, S3, CloudFront, EC2, ECS, ECR, Lambda, RDS, DynamoDB, CodeCommit, Route53, Elastic Load Balancing and CloudWatch.

Docker

I develop and deploy all larger back-end apps inside a Docker container. It's a great way to encapsulate the environment where apps run.

Apps I have built

Camping Finland

The camping holiday guide in Finland. For iPhone.

The app features camping sites, national parks, overnight stays and highlights the most important service at the sites. It calculates travel time and distance estimates and provides turn-by-turn navigation.

Camping Finland includes all the motorhome and caravan shops and most of the service shops.

Development and marketing time 240 hours. Total cost of development and distribution 24 100 EUR.
Latest series backends

Latest messaging backend for web and mobile apps.

Build using server side Swift and Vapor framework. Runs on Ubuntu inside a Docker container. Deployed to various cloud platforms depending on the client requirements.

Development and maintenance time 384 hours. Total cost of development and distribution 38 400 EUR.
Lambdas as a serverless solution

Lambdas provide a lightweight and easy to manage solution for many back-end tasks. I have made a collection of lambdas that handle API calls, data manipulation, messaging, and monitoring.

I use Node.js to implement lambdas. It provides a quick way to develop and deploy the needed functions for every day use.
Bedrock mobile app backend

Battle tested back-end powering mobile and web apps. Implemented with Swift using Vapor framework and running in AWS.

Under active development.
Available

Easy way to watch available disk space. Available shows free disk space in the menubar. You can select a hard disk and set an alarm limit.

If the free disk space decreases below the set limit the app displays a notification and the menubar icon turns red.

Supports light and dark modes.

Development time 11 hours. Total cost of development 1100 EUR.
Libi - Library Inspector for Final Cut Pro X

Quick and easy way to look inside Final Cut Pro X libraries. Libi shows you all the events inside a library with some detailed information like when the library was last modified or when an event was last edited.

Size on disk shows which libraries and events eat most of your disk space and a visual Render Files Ratio display tells how much of the event size is allocated by generated render files.

Development time 116 hours. Total cost of development 11 600 EUR.
Faded - Safari App Extension
Bright colors can be distracting, especially when consuming web content in the dark. Faded brings 5 filters to tone down a web page.

Filters:
- Faded - decreases saturation and reduces brightness.
- Dark - cuts down brightness to 55% and desaturates colors.
- Grayscale - wash out almost all the colors.
- Noir - high contrast black and white filter.
- Sepia - warm brown colors with slightly reduced brightness
Development time 29 hours. Total cost of development 2 900 EUR.
