Cut AWS infrastructure costs by 50% by moving background database tasks to a more efficient system (SQS + Lambda), eliminating crashes during peak traffic. Played a key role in preparing the MVP for launch, ensuring stability and addressing all blocking issues.

Reduced prompt size by 80% by replacing raw data injection with RAG-style tool calls, enabling consistent multi-turn interaction without hitting model limits. Improved result relevance with a custom geolocation-based scoring algorithm, prioritizing schools and jobs by proximity to the user's location.

Made the application portable by redesigning existing workflows to use an external Python package for integrating multiple data warehouses. Solidified codebase by applying best practices and increasing code coverage from 43% to 70%.

Designed and implemented the full architecture from scratch for a niche fishing platform. Led and mentored a junior developer through all development phases: planning, coding, testing, and deployment.

Helped 50% of attendees make a career change by using a highly-intuitive framework to guide them from programming basics to designing Python web applications. Successfully mentored and helped up to 40 students from Romanian technical universities gain an overview of Python applications and achieve a Google program diploma.

Ensured 100% platform stability and novelty for 3M+ students and 200k+ teachers by decreasing reported bugs and designing new features implemented quarterly. Successfully delivered a fully functional solution in 30 days, enabling teachers to provide recorded courses during the pandemic lockdown.

Increased revenue and clients' capital by up to 20% by designing custom-oriented applications served through a web interface. Achieved this by in-depth researching client requirements and transferring them into database, API, and user interface implementations.

Completed a trainer accreditation program, focusing on developing skills to effectively deliver training and educational content. This program enhanced my abilities to guide and mentor individuals in various technical subjects.
