01
Backend and e-commerce
You are a backend engineer with a strong e-commerce background, mainly PHP / 1C-Bitrix / MySQL / nginx / integrations / scaling.
Personal experiment
ChatGPT, the usual suspect.
Me Through ChatGPT’s Eyes
What does ChatGPT really know about you?
After asking ChatGPT a few more questions, I got some pretty strange answers and decided to find out what profile it had built about me from the history of our conversations.
01 / Context
What turned out to matter
Here is how ChatGPT reduced my profile to the points most useful for future conversations.
02
Moving toward product
You are moving toward a Technical Product Manager / Product Engineer role, where the full cycle matters: understand the business problem, design the solution, build an MVP quickly, and test the hypothesis.
03
AI as a working tool
AI development tools are a working instrument for you, not a toy. You regularly compare JetBrains AI Assistant, GitHub Copilot, Codex, and DeepSeek, focusing on agent mode, project understanding, price, and practical effectiveness.
04
PhpStorm and its ecosystem
PhpStorm is your main IDE, and integrating AI into the JetBrains ecosystem matters to you in particular.
05
Automation
You like automation. Common tasks include APIs, GitHub/GitLab/Bitbucket, RSS, content publishing, video, Whisper, integrations between services, cron/systemd/Docker.
06
Your own news hub
You have your own news-bot/news-hub, where content is automatically collected, translated/processed, deduplicated, and published.
07
Infrastructure
You understand the server side and infrastructure well: Linux, nginx/Apache, VPN, Docker, Kubernetes, caching, reverse proxy, TLS, and operating web projects.
08
A practical style
You prefer practical answers. It is usually more useful to give you a working option, commands, a config, or an architecture straight away than to explain theory at length.
09
Economics of decisions
When comparing solutions, economics matters to you: not only what is better, but how much it costs, how many credits/API calls it consumes, and whether the switch is worth it.
10
Japan
Japan is one of your main personal interests. You travel there regularly and know your way around transport, tickets, hotels, and everyday details.
11
AKB48 and music
You are actively interested in AKB48 and the Japanese music scene. Miyazawa Sae, Muto Orin, AKB48 Theater, concerts, and fan events come up often in your conversations.
12
Complex travel plans
You often plan fairly complex trips yourself, sometimes across several countries and cities. For travel questions, specific routes, logistics, and a reality check are useful to you.
13
Natural English
You regularly write in English for Reddit and LinkedIn, and usually need natural, not overly “AI-ish” English without excessive formality.
14
Specifics over hype
In professional writing, you prefer specifics over grand claims. Real numbers and results are better than words like “high-load” without enough evidence.
15
Large e-commerce projects
You have experience with large e-commerce projects, including payments, delivery, 1C, loyalty/CRM, integrations, and infrastructure scaling. This context matters when discussing resumes, jobs, or architecture.
16
Cheap MVP first
You tend to test an idea with a cheap MVP first and only then make the architecture more complex. This shows in your own projects and in how you evaluate new services.
17
GitHub and automation
You use GitHub actively, including for your own projects and development automation.
18
Fewer unnecessary questions
You do not like unnecessary clarifying questions, especially when the existing context already supports a reasonable assumption and a solution.
19
You want the verdict
When choosing a tool, you usually want a final answer — “take X,” “stay with Y,” “the upgrade is not worth it” — rather than only a table of pros and cons.
20
Long-term context
It is useful for me to remember previous technical details because many of your questions continue old tasks: servers, GitHub, Neko/VPN, Bitrix, AI tools, news-bot, and so on.
i
This is roughly the set of context that can actually change my answers. There are many smaller details, but I would not consider them part of the “core profile.”
02 / Technical assessment
Strong backend, but broader than code
Based on what I know about your experience, I would rate you 8/10 as a backend engineer.
Today, your value is higher as a Product/Backend Engineer than as simply a Backend Developer.
8/10
Backend engineer
Product Engineer
8.5–9/10
Integration backend
8.5–9/10
Why not lower
You have more than “wrote CRUD in PHP”: your production experience is broad — e-commerce, payments, delivery, 1C, caching, search systems, infrastructure, migrations from one server to several applications and then to Kubernetes. You can also work through legacy, which is often more valuable for a backend engineer than knowing the latest fashionable framework. And you can take a task from a business requirement to a working solution on your own.
Strongest side
I would especially call out your integration backend. In that area, you are probably closer to 8.5–9/10: payment systems, logistics, CRM/marketing, 1C, external APIs, queues, and real operational constraints. This is experience that is difficult to get from pet projects alone.
Engineering mindset
Another strength is your engineering mindset around operations: nginx/Apache, Linux, TLS, Memcached, Docker, Kubernetes, HA, monitoring. For you, backend does not end at git push.
Why not 9–10
I have not seen enough of your current production code to give that score honestly. I cannot properly assess API design, testing, DDD, concurrency, profiling, security practices, code review quality, deep PostgreSQL work, or how cleanly you design new code without Bitrix/legacy constraints.
Assessment limit
A significant part of your experience is tied to 1C-Bitrix and the PHP ecosystem. That is absolutely real backend work, but compared with a hypothetical Staff Backend Engineer at a company like Stripe or Uber, the role usually also expects very deep distributed systems, databases, concurrency, observability, and system design experience.
03 / Level
Where you are on the ladder
Middle is long behind you. The most natural place to apply your strengths is where backend, product, and integrations meet.
01above level
Middle
You left this level behind a long time ago. There is no real question here.
029/10
Senior Backend Engineer
Confident yes: production, integrations, infrastructure, legacy, payments, external services, operations, and architecture decisions.
038–8.5/10
Lead / Tech Lead
A natural technical level where you need to understand business requirements, make decisions, and own the whole system.
046.5–7/10
Staff Backend Engineer
This requires evidence of scale: influence across teams, technical strategy, RFCs/ADRs, mentoring, and platform ownership.
05not positioned
Principal Engineer
This level usually requires even stronger organizational impact and deep technical specialization.
04 / Next step

02main focus

The most natural technical level for the breadth of your work.
03growth direction
Technical Product

Possibly the best overall match for your profile.
The main conclusion
I would not advise you to market yourself too heavily as a “pure PHP developer.” That artificially undervalues your experience.
Technical Product / Backend Lead
or Senior Product Engineer
Your potential problem in a Senior interview is actually the opposite: the interviewer may think you are overqualified or have already moved too far toward product and leadership.
The Lead test
You are given a legacy Bitrix system, growing load, many external integrations, and a business that needs new features every week. How will you develop it over the next two years? This is where your practical experience should show.
What to strengthen for Staff
Not another language or framework, but modern backend system design at a deeper level: consistency models, partitioning, event-driven architecture, idempotency, transactional outbox, distributed locks, failure modes, observability/SLO, capacity planning, Kafka/RabbitMQ internals, PostgreSQL performance, and architectural trade-offs.

Hiring manager recommendation
I would be more likely to invite you for a Lead Backend / Technical Product Engineer role than for a conventional Senior PHP Developer position.
