Tesfaye Kefene Team Lead RSVP Approved

Role: Product & Tech Lead; systems architecture and integrations owner. Contributions: Defined the voice→goals→calendar pipeline and acceptance criteria for each stage (capture, parse, plan, schedule, re-plan). Designed the scheduling engine that turns prioritized tasks into time-boxed events respecting availability, buffers, and working-hour prefs. Implemented calendar write flows and meeting-link creation. Sponsor tools / APIs used: Google Calendar API v3: freeBusy.query, events.insert with conferenceData.createRequest (Google Meet). Microsoft Graph: /me/calendarview, findMeetingTimes, /me/events, onlineMeetings (Teams links). Zoom Meetings API: POST /users/{userId}/meetings (Zoom link attach). Notables: OAuth flow design (token refresh/consent scopes), conflict detection & auto re-planning, data model review. Profile — Lyton Mhlanga (Member) Role: Frontend & Voice UX; real-time capture and review UI. Contributions: Embedded the ElevenLabs Convai widget (via <elevenlabs-convai> in frontend/index.html), wired session lifecycle, and transcript streaming. Built the “Plan Preview” interface: live transcription → goal/task extraction preview → user approve/adjust → schedule. Implemented auth/consent UI for Google/Microsoft; status toasts for conflicts/slippage. Sponsor tools / APIs used: ElevenLabs Convai Web SDK for low-latency streaming ASR + turn-taking. Google Identity Services (OAuth) and MSAL.js (Microsoft sign-in) for calendar permissions. Notables: Accessibility (keyboard/ARIA for voice controls), optimistic UI for event creation, error surfaces for expired tokens. Role: Backend & Calendar Integrations; persistence and webhooks. Contributions: Built Node.js services for intent ingestion → plan proposal → scheduling; exposed REST/JSON endpoints to the frontend. Implemented availability resolver combining Google freeBusy and Graph calendar view; normalized time zones. Created the reminder/updates loop (status webhooks from client, slippage detection, re-plan triggers). Modeled goals/tasks/subtasks/recurrence in PostgreSQL; added migrations and audit tables. tools / APIs used: Google Calendar API v3, Microsoft Graph Calendar, Zoom Meetings API (create meetings & attach join URLs). Notables: Rate-limit/backoff, idempotent events.insert, structured logging + health checks.

I’m a Computer Science and Mathematics student at Vanderbilt with strong experience in software engineering and AI/ML. I’ve worked on projects ranging from full-stack platforms like VUmble and Khanflow to AI research in retrieval-augmented generation and computer vision through fellowships at Cornell Tech and Break Through Tech AI. Recently, I’ve been developing chatbots, healthcare ML models, and real-time sentiment analysis pipelines. I’m particularly excited about roles where I can combine deep technical problem-solving with building impactful systems at scale.
Software Engineering Intern and AI/ML Intern
Building Khanflow. An AI-assisted scheduling and productivity platform that helps students and professionals manage tasks more efficiently by integrating natural language input with automated calendar and workflow generation.

I'm a Computer Science student at Vanderbilt University with a passion for building tools and scalable systems that make lives easier. I enjoy using my technical skills for engineering, creativity, and social good. In the past I've worked as a Software Engineer for Develop for Good making software for nonprofits around the globe. At Vanderbilt, I'm part of a student organization called Change++ that makes web platforms for nonprofits throughout the country
TypeScript, JavaScript, React, React Native, MERN stack (Node.js/Express, MongoDB), Expo, REST APIs / third-party API integration (e.g., Google Gemini), AWS S3, SendGrid, Jest, mobile & web application development, nonprofit / social-good tech
stackedOverFlag : React Native (TypeScript) trivia app built with Expo, integrating Google Gemini for hint generation. microlink : MERN URL shortener (React frontend, Node/Express backend, MongoDB) using AWS S3 for asset storage, SendGrid for email flows and Jest for testing. Ongoing Develop for Good / Change++ work building and deploying web platforms for nonprofits.

Sujal Neupane RSVP Approved

Student at fisk university
Profile — Sujal Neupane (Member) Role: Planning & NLP; summarization, goal extraction, prioritization heuristics. Contributions: Turned transcripts into structured intents (goals, tasks, dates, constraints) with validation and schema fallbacks. Wrote the prioritization and time-boxing logic (deadline proximity, effort estimates, dependency ordering, focus-block sizing). Implemented the re-planning logic for conflicts/slippage and partial completions. Sponsor tools / APIs used: ElevenLabs Convai (final-text + timestamps feed for NLP input). LLM API (function-calling / structured outputs) for summarization and extraction, feeding the backend planner. Notables: Few-shot prompts + guardrails, deterministic parsing, confidence scoring to request user clarification only when needed. TL;DR ownership map Voice capture & UX: Lyton (ElevenLabs Convai, GIS/MSAL UI). Intent → plan → schedule services & DB: Md (Node.js, PostgreSQL, Google Calendar, Microsoft Graph, Zoom). NLP planning & re-planning: Sujal (LLM structured outputs, heuristics). Architecture, integrations, and delivery: Tesfaye (Google/Graph/Zoom writes, conflict handling, product lead).
