Along the way, you are welcome to flag any other inconsistencies you spot, but de-duplication is the priority. You will receive the raw spreadsheet and a short set of matching rules I currently follow. After you run your process, I’ll need the cleaned file back plus a brief log of what was removed, merged, or amended so I can audit the changes quickly.

    I need to retire my old Microsoft Access commission-tracking database and move everything to a cloud-based interface that staff can reach from any browser. You will start with the full Access file (forms, queries, VBA, and data) and rebuild the same business logic online. Two elements must make the jump intact: • Customizable commission calculations that let me change rates, tiers, and effective dates without touching code. • Built-in reporting and analytics so managers can slice results by salesperson, product line, and period, then export to Excel or PDF. Beyond those, I’m happy to discuss best practices—user authentication, audit trails, or dashboards—if they fit naturally into the new architecture. I have no fixed preference for the front-end s...

    ...agent must accept a plain-language instruction from the chat UI, break it into a basic sequence of sub-tasks, and then execute each step without additional prompts. Typical actions include: opening pages through Playwright or Selenium, reading or writing local files, running terminal commands, and calling external REST APIs. Throughout the run it should store and retrieve context via a vector database (Chroma, Pinecone, or FAISS) so conversations remain coherent and previously gathered knowledge is reusable. Architecture guidelines • Language: Python • Framework: FastAPI or Flask (whichever you’re faster with) • Orchestration: LangChain or LangGraph for tool routing and memory • Containerisation: Docker, with an easy “docker compose up&r...
