Role: Document/data-matching engineer (contract, MVP-first) Core skills (must have) Solid Python; comfortable building and shipping a working pipeline end-to-end. OCR / text extraction from images and screenshots (Tesseract, PaddleOCR, or cloud document AI like Google Document AI / AWS Textract). Screenshots are clean inputs, so this is competence, not heroics. Data matching / entity resolution: fuzzy string matching, normalization of names/numbers/dates, similarity scoring — the real heart of the job. Confidence scoring and thresholding: building a "match / probable / flag for review" output, not just yes/no. Comfortable using LLMs/embeddings for semantic comparison where rules fall short. I am looking for someone in India to match timzone. Mumbai based dev is preferred How I Work — Project Engagement Principles Please read before we start. These are how I run every project so we are aligned from day one. None of this reflects on you personally — it is simply how I keep delivery clean, predictable, and fair to both of us. 1. The code lives in the project repository All work is committed to a repository I own, from the first commit. You are added as a contributor with the access you need. There is no separate or private copy — the project always lives in one shared place. 2. No single point of failure Work is documented well enough that another developer could pick it up. I may bring in a second contributor when it makes sense, and that is normal — not a sign of distrust. Knowledge stays with the project, not locked in one person. 3. Transparency and communication We hold a short weekly check-in with a working demo and a brief written status. You are comfortable explaining the reasoning behind your technical decisions when asked. Clear answers matter more than perfect ones. 4. Milestones and payment Work is scoped into milestones with agreed dates. Payment is tied to milestone acceptance, not deferred entirely to the end. Small, visible steps keep us both honest about progress. 5. Availability and priority We agree realistic timelines and the time you can commit. If you take on other work that could affect delivery, you tell me in advance. Surprises about availability are the one thing that breaks trust fastest. 6. Decisions and client communication I am the decision-maker and the point of contact for the client. You keep me informed; you do not communicate with the client or change scope on my behalf unless we have agreed it. One clear line of decision-making keeps the project sane. If these work for you, we will get along very well. If any of them do not, please tell me now — it is far better to align before we begin than to discover a mismatch mid-project.

Hi! Your focus on fuzzy data matching and confidence scoring is spot on — most projects treat matching as a simple yes/no, so "match / probable / flag for review" is the right move for real-world data. Noted your need for strong OCR and downstream entity resolution. My main work is SaaS, app, and workflow systems, so I usually build the pipelines around web stacks like Node.js and React. For OCR and data normalization, I have plugged Google Document AI and AWS Textract into node-based systems, including fuzzy string matching for compliance platforms. Noticed your principle about a shared repo and visible check-ins. That's how I run projects too, so the process is familiar. One thing to clarify — do you plan to bring in a Python specialist for the OCR/matching core, or would you consider building the pipeline with Node.js and connecting to cloud APIs? Happy to outline a first-phase approach integrating OCR, confidence thresholds, and review logic, free. For a sense of my approach, some related systems are shown at work.techindika.com. — Pradeep

I can't write an effective proposal yet—the project description is incomplete. It cuts off at "Solid Python; c" and I'm missing critical details to reference specific requirements. To write a proposal that follows the rules (especially mirroring a specific pain point from the brief), I need: 1. **Complete description** – What comes after "Solid Python; c"? What are the full skill requirements? 2. **Project scope** – What exactly is the "document/data-matching" task? (e.g., matching invoices to receipts? Deduplicating records? Parsing PDFs?) 3. **Deliverables** – What's the MVP scope? What format/output do they expect? 4. **Timeline** – When do they need this? Once you share the full posting, I'll write a tight 150-220 word proposal that: - Opens with a specific technical detail from *their* brief - Outlines a concrete approach (with one technical choice) - Closes with either a first-24-hours action or a clarifying question Can you paste the complete project description?

⭐⭐⭐⭐⭐ Senior Python & Data Matching Engineer ⭐⭐⭐⭐⭐ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Hello there, I am a Python engineer specialising in document processing pipelines and entity resolution systems with confidence-scored matching output. The real complexity in document matching isn't the OCR — clean screenshots are straightforward. It's the normalisation layer underneath: names with inconsistent formatting, dates in mixed formats, and numbers with varying separators all need to resolve to the same entity before fuzzy matching produces reliable confidence scores. Built an end-to-end matching pipeline using PaddleOCR for extraction, RapidFuzz for fuzzy string matching, and OpenAI embeddings for semantic comparison where rule-based matching fell short. The output produced three-tier confidence scoring — match, probable, flag for review — with thresholds tunable per field type. Your six engagement principles align exactly with how I work — shared repository from day one, weekly demo check-ins, and milestone-based delivery. Based in Mumbai, fully aligned on timezone. Is the matching primarily between two structured datasets, or does one side come from unstructured document screenshots requiring field extraction before comparison begins?

Hi. I'm a Data Engineering Student from Algeria. I'm interested to work with you on that project. I'm good at designing end-to-end Data and AI pipelines, and I've worked before with Mistral OCR for a project which took candidate CVs and produced a JSON output that included scoring, summary, and more. I'm pretty comfortable with LLMs for semantic comparison also as requested. I'm confortable with Python too, and I can ship really fast as long as there's good communication. I don't just code; I plan, I try to get as much context as possible to get the best results, and to get into the desired scale, with the desired costs.
