Senior Backend Engineer (Django, PostgreSQL, AI, AWS) -Individual Developer(No Agency)

@iosifpeterfi

Hi there, your goal to benchmark and visualize design patterns to guide refactors and governance is exactly what I help deliver. This is my speciality - turning messy half-finished code into trusted patterns and visuals that drive decisions. I'm Iosif Peterfi, 15+ years as a Senior Web Developer & CMS Engineer, based in Europe/Berlin. Check my portfolio: https://www.freelancer.com/u/iosifpeterfi My approach is business-focused: I'll clarify the outcomes you want, validate the data you extract from your codebase, review and tighten the graph data flow and queries, and deliver a clean, benchmark-ready dataset with practical recommendations. You'll gain clear risk reduction, a realistic timeline for moving from prototype to reliable insights, and measurable business value. Recently I helped a healthcare software vendor map design patterns in a graph-based tool. We boosted pattern-detection accuracy from 65% to 90% and cut data-cleaning time by almost half. Let's chat - I can walk you through my approach in 15 minutes.

@nicolasalexandro

Hey — saw your post about the Senior Backend Engineer role for your career-focused, mobile-first platform. With 60% of the product already done, the biggest risk now is integrating new features without breaking what’s working, especially around data models and API contracts. Quick question before I suggest an approach: Do you already have a clearly defined API spec and data model for the remaining 40%, or is that still evolving as you build? I’ve led Django/PostgreSQL backends on AWS for similar B2C platforms (with AI components on top of existing data models), so I’m comfortable jumping into an existing codebase and extending it safely. If you can share your repo structure, high-level architecture diagram, or any backend spec, I can review it and tell you how I’d approach the remaining work.

@artemp02

Hi, Is the main backend challenge right now API/completion work in the existing Django system, or the AI layer around RAG and vector search? I worked on production-focused backend systems where the main job was joining an existing codebase, improving API reliability, optimizing database/query behavior, and supporting launch without disrupting what was already built. I also have hands-on experience with generative AI integrations, including a RAG-based chatbot with query understanding, intent classification, entity extraction, hybrid retrieval, Reciprocal Rank Fusion, and source-grounded responses. Just wondering, is your current AI stack already defined, or do you want help refining the Django + PostgreSQL + vector DB architecture as part of the remaining backend work? HOpe to discuss more on chat Best Artem
