I fine-tuned the LLaMA 2 7B Chat model using a memory-efficient method called QLoRA, so it can run on limited hardware. The model was trained on a conversational dataset to improve its ability to understand and respond like a chatbot. I used 4-bit quantization to reduce memory usage and speed up training. Overall, the model achieved stable performance with improved response quality.

I developed a fully automated, end-to-end lead management workflow that captures inbound leads via webhook, validates and enriches their data, analyzes buying intent, and uses AI to score and classify them into HOT, WARM, or COLD tiers. Based on this classification, the system triggers real-time actions such as Slack alerts for high-value leads, personalized email outreach for warm prospects, and CRM tagging for nurturing cold leads. It seamlessly syncs with platforms like Salesforce and HubSpot, while maintaining robust observability through audit logs, metrics tracking, and structured error handling to ensure reliability and scalability.

The integration has been done to create an automated workflow system between Notion and Google Calendar. The existing Notion databases were reviewed and organized by improving their structure, naming, relationships, formulas, and templates. Automation was set so that when a show is confirmed, all related tasks are automatically created and linked to the show and artist with due dates. Release schedules also generate timelines and marketing checklists. Dashboards were created for artists and managers, and confirmed shows automatically create events in the artist’s Google Calendar with details

Experienced finance professional selling high-quality Excel business models

I cannot overstate how amazing Apurva has been in helping me set up an ad campaign for my product. She put together my website, integrated a payment checkout system with Stripe, set up a website management account with WordPress, set up an ad placement account with Facebook, helped me create a sales video for my ads, updated my website with new features and products. She was patient, checked in with me every day, and advised me whenever I needed to take action (change a password, update my email address, etc.). I was looking for a freelancer to complete my project from start to finish. I met with 3 different people before meeting Apurva, each of whom tried to sell me additional work or otherwise charge me more than than advertised. Apurva did none of these things- we agreed on a price and not once did she attempt to renegotiate our agreement. I was lucky to have found her.
