Most people know me as ABP. I joined RentPrompts as a GenAI intern in mid-2025. Within a year I was leading its agentic AI work and building HiringAnt as CTO. I designed HiringAnt from the first commit, wrote most of it, and took it to paying users. More than 3,600 job seekers and 160 employers have signed up, and it has read over 11 lakh job listings to find them matches. Alongside the products, I build software for businesses that need it to simply work: a website and CMS for a staffing company, a payroll portal that turns a spreadsheet into 173 salary slips a month. I like the whole job, not one layer of it: talking to the people who will use the thing, deciding what to build, shipping the frontend, the backend and the agents, then watching the numbers and fixing what they show. ## How I work - **Agents have to survive production.** A demo that works once is easy. I spend most of my time on what makes it work the thousandth time: structured outputs, retries, evals, cost tracking and human-approval gates before anything irreversible. - **Ship the product, not the model.** Users pay for an outcome. I start from the job they need done and pick the simplest system that does it, which is often less AI than expected. - **Own it end to end.** Frontend, API, queues, database, deploys, SEO, payments. One person who understands every layer moves faster than a relay of handoffs. - **Measure, then decide.** Every feature gets an event and every agent gets an eval set. Opinions lose to the dashboard. ## I also bring the users Most engineers stop at the deploy. I keep going, because a product nobody finds is not finished. - I market HiringAnt myself: positioning, landing pages, SEO and the paid campaigns on Meta that bring job seekers and employers in. - I make the ad creatives and reels myself, some generated with AI and some shot for real, from the script to the final cut. The top five HiringAnt reels have over 450,000 views. - I run Error by Night, my YouTube channel with 11.9K subscribers, where I script, shoot and edit coding tutorials. The most watched have over 160,000 views each. - So when I build something for you, I am already thinking about how it will be found, explained and sold. ## Experience ### CTO, [HiringAnt](https://hiringant.ai) Feb 2026 to now · Indore - Own the product and the whole stack: architecture, agents, backend, frontend and infrastructure. - Took the platform from an empty repository to paying users, with 3,600+ job seekers and 160+ employers signed up. - Run the engineering process: PR gates, hermetic tests, contract checks, nightly performance and load runs. ### Agentic AI Lead, [RentPrompts](https://rentprompts.com) Jan 2026 to now · Indore - Lead the design of multi-agent systems and autonomous agents with memory, tools and reasoning. - Work with product and design to turn agent capabilities into shipped features. ### GenAI Developer, RentPrompts Aug 2025 to Jan 2026 · Indore - Built multi-tool agents with structured reasoning and RAG, and the FastAPI services behind them. - Shipped Payload CMS + Next.js dashboards and a Dockerised stack with Nginx, SSL and Celery workers. ### GenAI Intern, RentPrompts Jun 2025 to Aug 2025 · Indore - Built AI agents and RAG pipelines with LangChain, and applied-AI prototypes that became product features. ## What I work with - **AI and agents:** OpenAI Agents SDK, Multi-agent pipelines, Function tools, Structured outputs, RAG, Evals and LLM-as-judge, Prompt versioning, LangGraph, LangChain, CrewAI, n8n - **Voice and real-time:** LiveKit Agents, OpenAI Realtime, Gemini Live, Silero VAD, WebRTC, WebSockets, Server-sent events - **Frontend:** TypeScript, Next.js 16, React 19, TanStack Query, Tailwind CSS, shadcn/ui and Radix, Framer Motion, Nuxt and Vue - **Backend:** Python, FastAPI, Pydantic v2, Celery, Redis, Node.js, Payload CMS - **Data and storage:** MongoDB, PostgreSQL, pgvector, Pinecone, ChromaDB, Cloudflare R2 - **DevOps and reliability:** Docker and Compose, Nginx, GitHub Actions CI gates, Vercel, Cloudflare, Sentry, Uptime probes, Load testing, Lighthouse budgets - **Product and growth:** Razorpay payments, Transactional email, GA4 and PostHog, Technical SEO, Meta Ads, Video editing ## Questions and answers **Who is Avanish Patidar?** That is me.

It runs a real first-round interview by voice, live, and I built it end to end. - A two-way conversation, not a one-way video: it asks, listens, and follows up on what the candidate actually said. - Structured rounds with the employer's own questions and hands-on tasks, done while the candidate shares their screen. - Every interview is recorded, with a timestamped transcript, a score for each question and a summary sent to the employer. - Integrity signals with timestamps: tab switches, lost window focus, a stopped screen share, answers that sound read out. - Candidates can practise on the same system with mock interviews before the real one. - The AI never decides who gets hired. It hands a ranked shortlist and the evidence to a person.

To start, email avanish.patidar07@gmail.com. ## Scalable AI products, zero to launch You have an idea or a rough prototype. I design it, build it and put it in front of real users, including the unglamorous parts that decide whether people pay. - Scoping what to build first - Full-stack build: web app, API, database - Auth, payments, email, analytics - Queues, caching and infrastructure that hold up as usage grows - Launch, SEO and the first iterations ## AI solutions and automation A workflow in your business that people repeat every day. I turn it into an agent pipeline that does the work and asks a human only when it should. - Multi-agent pipelines and tool design - Internal tools, portals and CMS builds - RAG over your own data - Human-approval gates and audit trails - Eval sets so quality is measured, not guessed ## Voice and interview AI Real-time voice agents that hold a structured conversation: interviewers, screeners, intake and support. - Low-latency speech in and out - Structured question plans and scoring - Recording, transcripts and review tools ## Launch, content and growth Getting the first users is part of the build. I set up the marketing that brings people in and make the content myself. - Positioning, landing pages and SEO - AI-made ad creatives and short videos - Meta ad campaigns, tracked to sign-ups and revenue - Video editing for product and social content ## Production hardening and tech leadership Your AI feature works in the demo and misbehaves in production. I find out why, fix it and leave your team with the process to keep it fixed. - Cost, latency and reliability audits - Retries, queues and structured outputs - CI gates, tests and monitoring - Part-time technical lead for a small team ## How it works 1. **Write to me.** Email what you are trying to do and what is in the way. A paragraph is enough. 2. **A scoped plan.** You get a short written plan: what I would build first, what I would leave out, and what it needs from you. 3. **Ship in the open.** Working software every week on a link you can open, not a status report. 4. **Hand over.** Code, docs and a running system your team can own. --- # Shop Kits I sell for people building AI products, made from what I learned shipping HiringAnt.
