Most developers will build exactly what you spec. The problem is that what gets specced is rarely what actually solves the business problem. The gap between those two things is where AI projects fail, and closing that gap before writing any code is how I work. I have been building production AI systems and full-stack platforms for several years. Not prototypes. Systems that handle real users, real data and real consequences when something breaks. TaxForce is a 37-agent system running inside a real CPA firm covering document intake, risk scoring, audit defense, deadline tracking and client communication. The Facebook Self-Healing Ads platform is a closed-loop AI system that monitors, diagnoses and fixes campaign performance without human intervention. PAM AI handles thousands of concurrent dealership calls across 8 plus CRM integrations. Dentva is a HIPAA-compliant SaaS handling patient scheduling in production daily. These are not templates strung together, they are properly engineered systems with error handling, logging and recovery paths built in from the start. Before this I spent a year and a half at Turing doing RLHF and model evaluation on the OpenAI and Claude model families. That experience shapes how I evaluate AI output and design systems that behave reliably rather than impressively in demos. On the full-stack side I was CTO on RIZZ, a React Native dating app that grew past 100K users. I have worked on Junia AI, Slides and TopSocialAI across multi-tenant architecture, real-time systems and mobile at scale. These are confirmed production experience not claimed skills. The stack I work in daily is Next.js, React, TypeScript, Python FastAPI, Node.js, Supabase, PostgreSQL, LangChain, LangGraph, OpenAI, Anthropic API, Retell AI, Vapi, Twilio, ElevenLabs, Deepgram, n8n, Make and AWS. If you are building something in agentic systems, AI automation, full-stack SaaS or voice AI and you want someone who will tell you honestly what the right approach is before agreeing to build it, that is the conversation I am interested in having.

I design covers and turn manuscripts into books people actually want to read. Not just formatting. Not just covers. I create KDP and B&N publication-ready books and digital publications that look professional, read beautifully, and meet industry standards from page one to the final export. My work lives where publishing expertise meets great design. While many formatters focus only on technical requirements, and many designers focus only on aesthetics, I combine both to create books that are visually polished, structurally sound, and ready for print or digital distribution. What I do: * Book Cover & Audiobook Cover Design * Ebook & Print Book Formatting * Book Interior Layout & Typesetting * Children's Book Illustration * Magazine & Editorial Design * Reports, Documents & Presentations * Ebook Design & Conversion * Amazon KDP Publishing Support * Typography & Visual Storytelling * Proofreading & Content Refinement According to my clients: * Great Communication * Professional Results * Detail-Oriented Execution * Smooth, Stress-Free Process My publishing style? * Clean enough for major publishers. * Creative enough to stand out. * Professional enough to inspire trust. * Strategic enough to enhance the reader experience. I've worked with authors, publishers, businesses, and creative teams on everything from children's books and magazines to business reports and Amazon bestsellers. What do you get? * Publication-Ready Files * Professional Formatting * Thoughtful Design * Publishing Expertise * Fast Communication * Reliable Delivery My goal isn't just to make your book look good. My goal is to make it look like it belongs on the shelf beside the best in its category.

Hi! 👋 If you’re looking for someone who knows HubSpot beyond the surface, you’re in the right place. For the past 7+ years, I’ve worked directly in Sales and Marketing Operations roles, building real-world systems, automations, and processes inside HubSpot for fast-growing companies. HubSpot has been my daily workspace - not just a tool I “know”, but the one I’ve used to help teams get organized, automate, and grow. 🟣 Here’s what I help clients with: ➤ Process Blueprinting & Workflow Buildouts ➤ Sales, Marketing & Service Hub Setup & Automation ➤ HubSpot Integrations (yes, the tricky ones too) ➤ Data Cleanup & CRM Optimization ➤ Custom Reporting for Sales & Marketing Teams ➤ Automating repetitive tasks so your teams focus on revenue, not admin work On top of that, I’m 33x HubSpot Certified - which simply means I’m obsessed with staying sharp and making sure I know every new feature HubSpot rolls out. 💬 A quick note While I’m new to Upwork, I’m not new to HubSpot or RevOps. I’ve recently started offering my services here after years of working behind the scenes for companies who needed their systems to just work. If you’re a startup, SMB, or founder who wants someone to come in, make sense of the chaos, and set up HubSpot properly - I’d love to help. No bloated proposals, no shiny PowerPoints -- just solid, actionable work. 🔌 Tools I often integrate with HubSpot: ➤ Make.com ➤ Clay ➤ Apollo.io ➤ ZoomInfo ➤ RingCentral ➤ Zapier, Slack, Google Workspace, Typeform, Aircall, Calendly, and others. I’m easy to work with, I’ll speak your language (not just CRM jargon), and I care about getting things done right. 👉 If you think I might be a good fit, I’d love to hear about your project.

Hi, Kaushik here. A lead-generation engine I built generated $400K+ in qualified leads in under 90 days. An ERP automation I built for an export company converts 600 to 800 accounting vouchers from Tally to ERPNext in under 60 seconds each, down from 5 to 7 minutes a voucher by hand, saving 90+ hours of retyping and $45K to $65K in payroll every year, live in 2 weeks. An agentic workflow I built over meeting transcripts recovered 1+ hour a day of combined team time. Before this, across 8 years of hardware product development, I stopped $650K-per-incident losses and cut service downtime 83% at a $300B semiconductor equipment company, then drove $1.5M in annual procurement savings across 40+ components while growing supply capacity 500% in 10 months at a fast-scaling EV manufacturer. I design and build AI systems for manufacturers, labs, and hardware companies: RAG (retrieval-augmented generation) pipelines, multi-agent and agentic workflows, LLM integrations, and the automation that connects them. Python on the backend, real API and data integration, built to run inside live operations instead of a demo. Eight years on manufacturing lines, procurement teams, and testing labs is why the AI architecture I design holds up against real data, accuracy, and security requirements. If you need a partner to design, integrate, and scale AI systems, RAG, multi-agent orchestration, or the automation that ties them together, send me a message with what you are dealing with.
