What I'm looking for

I seek a quality-focused role with support for attention to detail. I want to work on impactful projects that add value to users' lives. Learning and growth opportunities are important, as is collaboration. I value a space that encourages ideation and considers everyone's suggestions.

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.
