I specialized in third-party API integrations and building web applications. What I offer: - API Integration with any 3rd Party systems - Building custom web applications from scratch - Solving any Golang related task - Consulting clients with anything about the technology and helping them find the best solution for their problems My API integration expertise and some projects I worked on: I wrote software solutions for syncing orders, products, customers, categories, and other resources between e-commerce platform APIs and different ERP APIs. Also, I integrated many financial schemes through their APIs, like RT1, SEPA, Faster Payments, SWIFT, etc., to allow banks to safely exchange money in real-time on the Internet. Besides that, I used many other systems with well-known public APIs like Stripe API, authorize.net API, DHL API, Slack API, etc. Besides API Integration, I have expertise in building web applications using Golang. I've built many web applications from scratch based on Golang. Some of them: Custom CRM software, Veterinary management software, Rest API testing services, Warehouse management software, and many more. Consulting clients about the technology and finding the best solutions for them is also what I am doing. If you are a business owner with little experience in IT, I can advise you on how to digitalize and automate your business processes. In general, I have experience with 14+ years of building complex systems and microservices in various technologies, such as Golang, Java, PHP, Ruby, Javascript, Vue.js, Docker, Kubernetes, AWS, etc. I've worked for years in agile cross-functional teams. I had different roles and responsibilities, such as developing, deploying, monitoring software, modeling databases, and leading engineers. I pay a lot of attention to testing and firmly believe that automated tests are essential for every software.

Welcome to my profile. my motto is, customer satisfaction can only be guaranteed if development is carried out strictly according to defined development processes. For this reason and for your protection, I will only process orders where the customer can provide me with clearly formulated requirements. Of course, this is an accompanying process in which I am happy to provide assistance. Whether privately or professional, I work strictly according to the development model that I think fits best to your project (e.g. V-model). My typical software development approach (Lifecycle) looks like this: MS0: Determine framework conditions of the project MS1: Requirements specification MS2: Architectural design MS3: Implementation MS4: Testing and Verification MS5: Release MS5: Documentation MSX: Maintenance Due to years of work as an embedded software designer, I can now offer a wide repertoire of know how: Bootloader designs RTOS based designs Low Power designs Working with Git Designing Drivers Hardware Platforms: STM32 Cypress TI Silicon Labs Nordic Connectivity: BLE WiFi LoRa USB 2.0 Fieldbus If my repertoire appeals to you I would be pleased to hear from you.

12 years of software development experience of working in product based and consulting companies including banks, IT consulting agencies and startups. Eager to build transparent communication with customers. The project starts from defining the requirements. Effort spent on clarification of a task always pays off. For that I am always happy to make text or video chats. I know how important it is for customers to be aware of the current status of the project. I always create a Trello board (except for the most simple ones) where you can see the current status of all tickets. I am pretty confident about my hard skills too. I am focused on the following tech stack: PHP (with Laravel or Symfony frameworks), Node.js, React (that also means that I know JavaScript and TypeScript). For sure I use the tools which are required for development in 2023: Git, Docker and Amazon Web Services (EC2, ECS, S3, CloudFormation, CodePipeline, Lambda, CloudWatch, CodeCommit, SQS, SNS, EventBridge, Secrets Manager, etc.). I can establish and manage CI/CD processes. I use unit testing and end-to-end testing tools. I have worked with AWS RDS, AWS DynamoDB, Oracle, MySQL, PostgreSQL, SQLite, MongoDB, Redis databases. If you have any questions you are warmly invited to send me a message. Kind regards, Doszhan
