**The Role** You inherit a system someone else built, work out how it behaves, extend it, and leave it working. Most of the work here is not greenfield. In your first months you would own features inside one of our production systems: a video ad assembler, a static ad generator, a pre-lander builder, or the media buying engine. You read code you did not write, extend it without breaking the parts already shipping every day, and keep the cost per generated asset visible. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ **Essential** - Strong TypeScript. You have shipped and maintained a [login to view URL] application in production. - Comfortable with a Postgres schema and an ORM (Prisma in most of our systems), and with the request path of a real web app. - Practical experience calling AI APIs from production code (Anthropic, OpenAI or similar), including error handling, retries, and cost per call. - You read the code before trusting the documentation, and you extend rather than rebuild. - You write your own tests, and you prove a change did not break what already shipped. - Working written English. The team spans several countries, and most communication is written. - Self-directed. You unblock yourself, and you flag a blocker early. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Valued, not required - Python and FastAPI. One of our systems is a Python research backend. - Vercel, Supabase, Clerk, database migrations. - Media generation APIs (image, video, voice), and reasoning about credits and spend. - Ecommerce or performance marketing background, Meta Ads, Shopify. - Experience owning a system end-to-end rather than working a ticket queue.

Hi, I'm Elias, a Miami-based senior software engineer with 20 years of experience in AI automation and backend systems. I've carefully reviewed your project, and I understand that your main goal is to inherit, analyze, and enhance an existing AI automation system to meet your needs effectively. I've built similar systems focusing on secure architecture, scalability, and maintainability. My approach would involve a few simple phases: 1) Analyze the current system to understand its behavior and workflow. 2) Identify areas for extension and improvement based on your objectives. 3) Implement the necessary enhancements and ensure smooth integrations. 4) Conduct thorough testing to validate performance. 5) Provide ongoing support to help the system evolve with your needs. Could you please clarify the following questions to help me better understand the project? 1) What specific functionalities do you want to extend or enhance? 2) Are there particular integrations with other systems that should be prioritized? 3) What edge cases or specific business rules should I consider to ensure proper system behavior? I've successfully completed similar projects before. Most of my work was done under NDA, so I can't share links, but I'm happy to discuss the architecture and features in detail. Additionally, I can provide a maintainable codebase that will facilitate future updates.

AI Automation Expert Hi, I have experience integrating AI APIs such as OpenAI and Claude, including handling failures, retries, API costs and production reliability. I’m also comfortable working with Python/FastAPI when required. I’ve worked on AI platforms, automation systems, SaaS applications and media-related workflows where performance, reliability and cost control are important. I regularly use Claude, Codex and Cursor for AI-assisted development while keeping proper engineering practices, testing and code review in place. I’m comfortable with Vercel, Supabase, database migrations, REST APIs and third-party integrations, and I can quickly understand an unfamiliar codebase before making changes. I also write tests around new functionality and regression cases so existing production features remain stable. I’d be happy to review your current system, understand which product area I would own first, and discuss how I can contribute long-term. Thanks! Purnima

Hi there, You’re inheriting a production system and need someone who can read the code, extend it safely, and keep shipping without breaking what’s already live. I have strong expertise in Python and AI Automation, and I’d approach this by tracing the existing request flow, mapping the AI call paths, adding resilient retries and cost tracking, then writing tests around the touched paths before any rollout. Best regards, Ian

Hello!, This is James from Hollywood... I read the role carefully, and the real challenge here is not just building automation, but inheriting someone else’s system, understanding how it behaves, and extending it without breaking what already works. That’s exactly the kind of work I like. My approach would be: 1. Audit the current Python/AI workflow, dependencies, and edge cases 2. Map the system behavior clearly so nothing is guessed 3. Improve or extend the automation in small, safe phases 4. Test thoroughly, document the changes, and leave it maintainable I’m a senior Full-Stack and AI Engineer, so I can handle both the logic and the surrounding architecture. I care about clean handoff, stable execution, and making sure the project doesn’t become a black box for the next person. Relevant work I’ve done: - AI workflow engine for a small logistics ops team - Python-based lead enrichment automation for a B2B SaaS tool - Internal dashboard with LLM-assisted task routing - Data sync automation between custom APIs and CRMs A few quick questions: 1. Is the current system documented, or should I reverse-engineer it first? 2. For phase one, is the priority reliability, new automation, or both? 3. Are there any critical tools, APIs, or services that must stay supported? If you want someone who will trace the system properly and improve it without shortcuts, I’d be glad to jump in.

Helo, What happens to a queued render job when the AI API call succeeds but the process dies before the Postgres row gets updated, and does the media buying engine currently have any way to tell a stalled asset from one still legitimately in progress? This role is really about inheriting other people's decisions and not breaking what already ships, which is a different skill than building from scratch. Given the four systems mentioned, video ad assembler, static ad generator, pre-lander builder, and media buying engine, I'd start by mapping how each one calls its AI provider and where cost per generated asset is actually tracked, before writing a single line of new code. I can start on a small owned feature this week if that's useful. Thanks.

Hi, This is a maintenance-and-extension role, so the priority is improving features without changing production behavior. I’ve worked in codebases where the first step was understanding how requests, Postgres/Prisma data, and external AI calls flow through the app before making changes. My approach would be to trace one feature end to end, from request entry to database write to AI API call and response handling. Then I’d implement the update with tests around the existing flow, so current video/ad generation or pre-lander paths continue to ship safely. For this kind of system, clean TypeScript, careful schema updates, measurable error handling, and reliable retry logic are key. I’d also review deployment safety, logs, and edge cases around failed generations and spend tracking. My first question would be: which production flow should be extended first, and where is cost-per-call or asset spend tracked today? I can review this on Freelancer chat/video call from 11 AM–8 PM IST. Regards, Ghanu & Samir KESHAV INFOTECH

You need someone to inherit existing production systems, extend them carefully, and keep generation cost visible—not rebuild from scratch. I’ll read the current codepaths first, ship features inside the live stack, add tests around the change, and handle AI API calls with retries and clear failure behavior. I’m comfortable with production debugging, written English updates, and self-directed delivery while flagging blockers early. Quick questions: is the posted budget a trial or full-time monthly amount, and which system would I take first? Share hours/week and stack access expectations, and I’ll send a practical 30-day plan—want that next?

The key requirement is keeping the entire booking journey on-site while synchronizing live availability, rates, reservations, and Paystack payment status reliably. I would structure the platform around a lightweight CMS with a dedicated booking layer rather than forcing hotel logic into standard e-commerce products. Rooms, future villas/suites, rate plans, packages, promotions, and availability would use a flexible inventory model so new accommodation types can be added without rebuilding the system. The booking flow would cover date search, live availability, room selection, guest details, payment, confirmation, and booking management. Paystack would be integrated with verified callbacks/webhooks so reservations are confirmed only after validated payment, with clear handling for failed, pending, or duplicate transactions. The admin dashboard would let staff manage inventory, rates, bookings, promotions, articles, menus, galleries, and media without developer assistance. I would also include responsive testing, SEO structure, performance optimization, GDPR-conscious data handling, documentation, and deployment. Do you already have a hotel booking engine/PMS API selected, or should I recommend the booking engine and define the integration architecture as part of the project?

If the date picker lets users pick a past date, the booking flow could break when the payment gateway validates the schedule. I'll lock the calendar to future dates on server and sync it with front‑end using React state so UI never shows invalid options. The admin panel will store each tour’s calendar in a MySQL table, making it easy to export bookings to CSV. A common pitfall is relying on client‑side price calculations, which can be tampered before Stripe or PayPal processes the charge. I'll compute totals in PHP, verify them again in the payment webhook, and only then confirm the booking. Ready to start immediately and get the site live on your host with SSL.
