Senior Software Engineer, AI Native, AWS Cloud for SaaS, GIS & Fintech

Reliable, Clear Communication & Committed for the long-term I do the work myself, commit to your project, solve problems, and deliver end-to-end results. Some clients I've worked with have stayed with me for 10 years. I communicate early and have mastered async communication with 12 years of experience. Clear expectations, I tell you early if I've found a blocker or need research. AI-First development I use AI to boost productivity combined with 17 years hands-on software engineering experience to build a proper software architecture that is scalable & maintainable. I automate repetitive tasks, allowing me to focus on more complex and creative aspects of the project. CTO / Product Mindset I understand your business and goals first before code. I know how to expand from a small brief into a workable solution. I suggest the most optimal solution to meet your business needs. Proactively engage with the project, improve it and don't wait for assigned tasks.
