Software engineer mainly interested in backend-focused work, but open to doing some frontend too in full-stack roles
What I'm looking for
Software Engineer. Proficient with Haskell, TypeScript, SQL, AI, and more. I like to build things.
My foray into software development began with a fortuitous encounter at a career fair during my ninth-grade year. This chance discovery of software has since evolved into a deliberate pursuit, fueled by a fervent commitment to the craft.
I derive immense satisfaction from engaging with every facet of a product, from constructing intuitive user interfaces to developing robust and efficient backend systems. I have a particular affinity for automation and am unwaveringly committed to continuously refining my skills. Guided by a focus on quality and impact, I utilize programming to breathe life into ideas and relentlessly strive to refine products to their utmost potential.
