Felix Rojas
I am a Senior Software Engineer with 7+ years of experience delivering scalable web, mobile, and AI solutions through technical consultancy and staff augmentation. I have a proven track record of architecting and shipping applications for diverse industries including FinTech, HealthTech, and enterprise SaaS. My expertise spans modern JavaScript ecosystems (Node.js, Next.js, React Native), Python (AI/LLMs, RAG pipelines), and robust backend infrastructure (Supabase, Firebase, AWS, SQL/C#). I thrive in high-velocity, autonomous environments where I can take full ownership of the tech stack, whether that means rescuing a legacy system or building a zero-to-one MVP, I want to mentor because Ive realized my biggest impact comes from helping other engineers stop just writing code and start thinking like system architects who can solve real-world problems.
