Product-Ready AI Full Stack Software Engineer & AI Agents @ OnceHub | Ex-PwC | Angular | FastAPI | LLM Integration | Python | AWS & MS Azure Certified | Cloud & DevOps

About

Full-stack engineer building AI-native systems at OnceHub, a global SaaS scheduling platform. My work spans Angular + TypeScript frontends, FastAPI + Python backends, and most recently production AI agents: I do prompt engineering and conversation design on a phone calling agent that automates booking, and I'm contributing to LLM-powered booking automation that removes manual scheduling work end to end. I care about backend systems that ship and matter, not just infrastructure for its own sake. At OnceHub, that's meant refactoring FastAPI endpoints to async and cutting response times by ~40%, and redesigning core workflows in a way that drove an 80% reduction in related business costs. Outside work, I build things that solve problems I actually have. I'm currently building an AI job-application co-pilot (Chrome extension, Claude API) after getting tired of rewriting the same cover letter answer 40 different ways and a voice + chat AI scheduling assistant, because I wanted to see what AI-native booking could look like beyond what I build professionally. Background: AWS Certified · Microsoft Azure AI-900 · IEEE INCET 2024 published researcher (co-authored ML research selected from 400+ international submissions) · BTech Computer Science, UPES (GPA 8.43/10). Currently open to full-stack and AI engineering roles in Germany, the Netherlands, or the UK.

Work experience

Software Engineering Technical Associate at OnceHub, Jul 2025 - Present · 1 yr 3 mos, • Co-Engineered production phone calling agent handling with autonomous completion using LLM function calling + real-time prompt optimization, eliminating manual booking calls. • Co-building a production AI booking agent that converts manual scheduling requests into fully automated end-to-end booking flows integrating LLM function calling with FastAPI async orchestration and an Angular real-time UI, reducing human intervention in the booking loop by ~50%. • Built real-time booking status updates using WebSockets between FastAPI backend and Angular frontend users see live state changes without polling, eliminating unnecessary API calls per session. • Architected Angular 17 features using Signals and OnPush change detection — reduced unnecessary re-renders, improving perceived performance on scheduling views. • Containerized 2 services with Docker + Docker Compose; extended Jenkins CI/CD to auto-build and push images on merge — cut deployment from manual releases to under 8 minutes end-to-end.
