what you’re building isn’t a reminder tool, it’s a real-time, multi-channel state machine driven by ai, and that’s exactly the kind of system where architecture matters more than features. i work at the intersection of spring boot state orchestration, react-based workflow builders, and real-time ai integrations, and i’m comfortable solving latency, interruption handling, and conversational edge cases rather than just wiring apis together. relevant experience i’ve built systems using websockets, streaming apis, and llm-based intent classification, including real-time interruption handling, workflow transitions, and async event processing across voice, messaging, and email channels. stack alignment • react 18 + typescript, react flow, complex client-side validation • postgresql workflow graphs, state history, auditability • elevenlabs, openai, twilio, resend • oauth or jwt-based secure apis with openapi docs i’m fluent in english and comfortable tuning conversational nuance, pacing, and interruption behavior for native-quality voice bots. if you want someone who can design the engine, not just assemble the parts, i’m ready to step in. best regards jenifer

I HAVE READ AND UNDERSTOOD YOUR REQUIREMENTS IN DETAIL AND CAN OWN THIS PROJECT END-TO-END AS A SENIOR FULL-STACK DEVELOPER. I WILL PROVIDE 2 YEAR FREE ONGOING SUPPORT AND COMPLETE SOURCE CODE. WE WILL WORK WITH AGILE METHODOLOGY AND WILL GIVE YOU ASSISTANCE FROM ZERO TO PUBLISHING ON STORES. I HAVE 10+ YEARS OF EXPERIENCE WITH JAVA (SPRING BOOT), REACT + TYPESCRIPT, POSTGRESQL, REAL-TIME SYSTEMS, AND AI INTEGRATIONS. I HAVE BUILT PRODUCTION WORKFLOWS USING WEBSOCKETS, VOICE/STREAMING APIS, AND LLM-BASED INTENT ANALYSIS, INCLUDING STATEFUL ORCHESTRATION AND LOW-LATENCY EVENT HANDLING. BACKEND ARCHITECTURE APPROACH: I WOULD USE A STATE MACHINE PER WORKFLOW WITH EVENT-DRIVEN PROCESSING. WHEN A USER INTERRUPTS THE AI MID-SENTENCE, THE CLIENT SENDS AN INTERRUPT EVENT OVER WEBSOCKET, THE BACKEND IMMEDIATELY EMITS A STOP SIGNAL TO ELEVENLABS STREAM, UPDATES THE CURRENT STATE, AND RE-ROUTES THE NEW INPUT THROUGH THE INTENT ANALYZER TO CONTINUE THE FLOW WITHOUT RACE CONDITIONS. I AM COMFORTABLE BUILDING THE NO-CODE WORKFLOW EDITOR, REAL-TIME VOICE BOT LOGIC, INTELLIGENT INBOX, AND SECURE REST APIS AS DESCRIBED. AVAILABLE TO START IMMEDIATELY AND WORK LONG-TERM. I EAGERLY AWAIT YOUR POSITIVE RESPONSE. THANKS

Hello There!!! ⚜️⭐⭐⭐⭐⚜️(( Architecting Real Time AI Driven AR Automation with Voice and Multi Channel Workflows ))⚜️⭐⭐⭐⭐⚜️ What you are building goes far beyond reminders. This is a real time orchestration engine where AI voice, messaging, and workflow state must stay perfectly synchronized, especially in sensitive financial conversations. That combination of Voice AI, intent detection, and workflow control is where most systems break if not designed carefully. You are looking for a senior full stack developer who can architect a Spring Boot core capable of handling complex state machines, while delivering a fast, intuitive React interface for visual workflow design and operator visibility. I bring hands on experience designing Java based backends with real time event handling, WebSocket driven integrations, and React applications that manage deeply nested state without sacrificing performance. I focus on building systems that stay predictable under interruption, latency, and edge cases. Three critical pillars for this platform would be: 1. A resilient workflow engine that can pause, resume, and reroute actions in real time. 2. Low latency Voice AI orchestration that reacts instantly to human interruptions. 3. A visual editor that validates logic before execution to prevent costly mistakes. If this aligns with your technical vision, I would welcome a focused discussion on architecture, milestones, and delivery strategy. Warm Regards, Farhin B.
