  • Use Amazon S3 for storing and serving assets and data
  • Work with Amazon Bedrock to integrate generative AI services (e.g., document processing, summarization)
  • Apply best practices in version control, testing, and security
  • Participate in code reviews, architectural planning, and agile team ceremonies

  • Awareness of security practices for serverless apps (IAM roles, API authorization, secret management)


    What we offer:
  • Long team focus: we create an environment of transparent communication, and minimal bureaucracy, which leads to long-term relationships.
  • Development of niche expertise: we are working in several niches, such as FinTech, healthcare, and logistics. Therefore, our employees can develop their own expertise in these domains.
  • Continuous learning: we create employee development plans / personal roadmaps /quick promotion processes.
  • Internal career development: 80% of our current executives were promoted to those positions within S-PRO. We encourage initiative. If a person wants to set new challenges and grow, we will definitely support them.
