What I'm looking for

I want a collaborative engineering role where I can build full-stack and mobile products, work with AI tooling, and grow technically while contributing to impactful projects.

I am a full-stack software engineer with one year of professional experience building modern web and mobile applications using React, Next.js, Nest.js and React Native. I have delivered production projects that include a legal SaaS platform, an AI-powered mobile expense manager, and an HR & Payroll platform, and I contributed to increased client acquisition and practical product outcomes.

I am a fast learner expanding into Agentic AI and related tools (OpenAI Agents SDK, LangChain, CrewAI) and I enjoy collaborating with product engineers and clients to translate requirements into working solutions. I seek opportunities to apply my technical skills across the full software development lifecycle and to grow by tackling new software development challenges.
