I live and breathe building things! When I'm not immersed in the world of IoT or crafting elegant code (my natural habitat, really), you can bet I'm already architecting my next creative solution. I'm driven by a passion for innovation, a healthy dose of grit to see things through, and a customer-first approach to ensure what I build truly resonates. In my free time? It's a safe bet I'm either devouring a new tech stack or vibing with like-minded creators β that's where the best sparks fly!
Developing AI voice agents and automation solutions for dental practices using modern stacks (reactjs, python, and low-code systems like vapi, make.com, and n8n). Specializing in prompt engineering for human-like conversational flows and creating innovative solutions to automate administrative tasks.
Processed and annotated ML training data for Alexa's natural language understanding systems. Implemented rigorous prompt engineering to fine-tune LLMs for accurate human query handling while minimizing hallucinations. Developed automation scripts and solutions that improved data accuracy within Alexa AI systems. Data engineered and trained models using AWS Sagemaker for predictions with high accuaracy.
Built custom automation tools using Node.js, Python, and RPA tools like UIPath. Notable projects include a KLM lost property communication system, a Content Generator for creating content automatically with AI APIs, a TikTok growth automation suite, a BOL.com inventory tracking solution, and a Goudengids data scraping script.
Developed web applications using React frontends and Flask backends for small businesses. Created complete solutions encompassing HTML, CSS, JavaScript, and Python frameworks, focusing on responsive design and functional APIs.
I'm the versatile tech partner you've been searching for! My sweet spot? Weaving cutting-edge AI-driven automations with robust full-stack development. But my repertoire extends further β I bring an artist's eye for compelling visuals and a sorcerer's touch with low-code platforms, transforming complex challenges into elegant solutions at lightning speed. My passion is to engineer experiences that are not just whip-smart and ultra-efficient, but also creatively dazzling and an absolute joy to use.
Built production-grade solutions using LLMs, RAG, and Stable Diffusion. Amazon-certified in Responsible AI and prompt engineering. Developed automations for actual KLM and BOL.com real-life use cases using UIPath and custom Python scripts that reduced manual work by 40%.
Shipped applications using React/Flask stacks with Azure deployment. Hackathon-winning developer (Developer Week 2024) with expertise in real-time APIs and payment integrations.
Engineered and processed 2M+ training samples for Alexa AI systems at Amazon for LLM training. Developed Python scripts to clean and process extensive data, leveraging advanced Python skills.
I bridge technical expertise with business outcomes, having delivered:
Combining 5+ years of full-stack development with frontline business experience smart automations and creativity. This dual perspective helps me create tools that actually solve user pain points while meeting technical requirements.
From optimizing Alexa's AI at Amazon to building client-facing chatbots, my work focuses on creating user-friendly tech that drives measurable results. Certified in both machine learning (Amazon MLU) and cloud platforms.
Listed below are some of the projects I've worked on. They range from basic web sites, scripts, web scrapers and AI applications.
