Hi, I’m Elias from Miami. I reviewed your role carefully — you need a steady, senior generalist who can ship features in a Python + React stack while actively improving code health: reviews, security hardening, tests, and CI/CD hygiene. The goal is sustained velocity without accumulating risk. I’d ramp up by mapping the codebase, deployment flow, and current risk areas, then own a predictable weekly loop: feature delivery + PR reviews, plus a security/test “maintenance budget” each sprint. Security work would focus on OWASP Top 10 with practical checks: authz boundaries, CSRF/XSS protections, input validation, dependency scanning, and safe secrets handling. I’m comfortable working in VS Code, reviewing React Flow code, and using AI tools to speed up implementation without reducing quality. I’ve worked in lean product teams where I was responsible for both delivery and technical quality—tight PR discipline, clear documentation, and early risk surfacing. I have a few questions for clarification: Q1. What’s the current backend stack (Django/FastAPI/Flask) and hosting environment? Q2. How do you run releases today (CI/CD, environments, test gates), and what’s the biggest pain point? Q3. Is the 20+ hrs/week expected within a specific timezone overlap window?

@temoberishvili

Hi, This reads like the kind of role I do best in — a small product team where one developer owns the full technical picture, not just feature tickets. Python backend and React frontend is my primary stack. I'm also comfortable with React Flow, database work, CI/CD pipelines, and the code review process that keeps a codebase healthy over time. On the security side, I actively look for OWASP Top 10 issues as I work — SQL injection, XSS, CSRF, broken auth flows — rather than treating security as a separate audit pass. It becomes part of every PR review and every feature I build. I use AI tools daily (Claude, Copilot) to move faster without cutting corners on quality. The ownership aspect matters to me — I'd rather flag a problem proactively than wait for it to become a ticket. Twenty-plus hours a week with 1–2 weekly syncs and async communication in between is a working rhythm I'm used to. Best regards,
