Senior Full Stack Engineer (TypeScript) - Generative AI SaaS

@augurstech

A Warm Hello! We are readily available to start working on this project! Although your posting mentions a preference for independent freelancers, we wanted to introduce our agency because we can provide the expertise of a senior full-stack engineer backed by an experienced technical team whenever additional architectural guidance, DevOps support, or specialized expertise is needed. This gives you the flexibility of working with a dedicated senior engineer while minimizing delivery risks during your critical launch phase. Answers to Your Required Questions 1. Are you an independent freelancer or part of an agency? We are a software development agency. For this engagement, we would assign a dedicated senior full-stack engineer as your primary point of contact, fully integrated with your existing team and supported by our internal technical specialists when needed. 2. Do you currently have any ongoing projects? Yes, as an agency we manage multiple client engagements. However, the engineer assigned to your project will be dedicated to your platform during the agreed engagement period, ensuring full focus on your delivery milestones. 3. When can you start? We can begin immediately after finalizing project discussions and onboarding. We would welcome the opportunity to discuss how our expertise can help ensure a smooth and successful public launch of your platform. Best Regards, Ana

Hi, this looks like a generative AI SaaS role where the real value is not just shipping TypeScript features, but keeping the product boundary between application logic and AI behavior clean as the system grows. The main engineering risk is usually orchestration drift: once generation flows, user state, and product logic get coupled too tightly, velocity drops and reliability gets harder to control. I've built several production systems like this and I usually structure them so the app layer, AI workflow layer, and persistence concerns can evolve independently. The closest examples in my background are Custom Feature Development & Integration, where I dropped into a live product, reviewed the codebase, and shipped maintainable enhancements, and AI-Driven Marketing Suite Development -- 2, where I built an AI-centered application with approval workflows and optimization loops. I typically design these systems with clear separation between ingestion or input handling, orchestration, and response delivery. That keeps feature work moving without turning every prompt change into an application rewrite. For AI reliability, I recommend explicit evaluation points, confidence thresholds, and fallback behavior rather than treating model output as inherently stable. If useful, I can start by mapping the current architecture and outlining the highest-risk areas in the generation flow. Thanks, Hercules

An 80% complete MVP heading into a launch sprint is a specific situation: the hardest part is usually not the remaining features but the performance and reliability issues that only surface under real traffic. That's where I'd expect to spend the first week or two, getting a clear picture of what's actually launch-blocking before writing new code. The Higgsfield comparison gives me a reasonable sense of the product shape: video generation pipeline, user-facing prompt interface, likely some queuing and async job handling behind the scenes. Happy to go deeper on any of that once I've seen the codebase. To answer your questions directly: independent freelancer, no conflicting commitments, available to start immediately. What does the current architecture look like around the AI generation pipeline, and where is the CTO seeing the most instability heading into launch?

Hello Zeroten Media need reliable generative AI pipeline. Current builds often suffer from latency spikes and context window bloat. I specialize in optimizing LLM workflows, specifically reducing inference overhead for media-heavy applications. Previously scaled similar content-generation infrastructure for high-traffic startups. Ready to audit your current stack and stabilize performance immediately. Can we discuss your specific latency requirements? Giáp Văn Hưng

I understand you're seeking a Senior Full Stack Engineer to finalize your Generative AI SaaS platform, aiming to compete with Higgsfield.ai. My experience building and launching similar AI-powered applications, including a recent project that saw a 30% increase in user engagement within the first month, directly aligns with your critical sprint toward public launch. I will focus on completing the remaining 20% of your MVP, specifically by developing the core AI model integration endpoints using Node.js and TypeScript, and building out the user-facing components with React. This will involve creating robust API routes for model inference and a responsive dashboard for users to interact with the generative capabilities, all deployed on AWS. What specific data validation or error handling requirements are in place for user inputs to the generative models? Ready to start as soon as you confirm scope.
