Product reliability
I help business owners understand failures and launch risks. You receive a diagnostic review and an action plan.
I'm Eldiyar, a systems engineer. I work on AI products, automation and payments where failures delay work or affect money and customer data.
Start by describing what is happening. You do not need to know the technical cause or choose a type of review yourself.
Tasks get stuck, actions happen twice, or AI service bills keep growing. An automation reliability review examines one important process and gives you a plan for addressing its problems.
Payment statuses disagree, transfers need manual checks, or blockchain fees are too high. A payment reliability review examines one payment journey in a crypto payment or wallet system.
You built a product with AI tools and are about to introduce real users, data or payments. A pre-launch review assesses the materials you provide: what was reviewed, which risks were found and what should happen before launch.
These outcomes come from engineering work on individual projects. A diagnostic review produces findings and a plan; the result depends on what those findings reveal. I do not disclose confidential project names or customer data.
Reports took 30–60 minutes to prepare. I designed the analytics system and the coordination between AI modules, allowing independent tasks to run in parallel. Report generation fell to 10–15 seconds.
I was responsible for the payment core and transaction tracking. Automating the resources needed for TRON and EVM transfers reduced blockchain transaction fee costs by 90%. The transaction tracking pipeline brought settlement latency down to 2–3 seconds.
I built media session isolation and the integration with AI providers. Reusing results and removing duplicate requests cut third-party API costs by 40%. The platform supported more than 10,000 concurrent simultaneous connections.
A diagnostic review of an agreed process, based on the materials you provide. I document risks, possible causes of failures and recommended priorities. You receive a written report and a video walkthrough. You can give the report to your developer or another contractor.
After the report, we define the next steps, scope, responsibilities and acceptance criteria.
For capacity, technical leadership, trading software and data processing, see other areas of work.
Diagnostic fees in US dollars:
We agree the fee before work begins. The report is ready within 3–5 business days of receiving the materials.
For the first conversation, describe what should happen, what happens instead and how it affects your business. The first 15-minute call establishes whether the problem fits my expertise and which materials are needed.
For the review, provide a system overview, a process diagram, sample event logs and screenshots of operating metrics. For AI products and automation, include settings with secrets removed. If your developer holds these materials, they will need to help prepare them. You do not need to read the code yourself.
Materials can be anonymized. Passwords, keys and access to the live system are not needed for the review. Your materials remain confidential. If implementation requires access, we agree it separately with the minimum permissions needed and the ability to revoke them.
I carry out the work personally. A materials-based review does not replace a full system assessment, a formal security audit or a legal opinion. Design and substantial interface development are outside its scope.
My working time zone is UTC+3. Payment is available by bank transfer, payment services, stablecoins or cryptocurrency.
Message me on Telegram with your concern about the product or process. We will arrange a 15-minute call first.
You receive a written report and a video walkthrough. The contents depend on the selected review and agreed process: a map of the key stages, identified risks and their trigger conditions, reasoned hypotheses about failures, gaps in observability and cost controls, and a prioritized now / next / later plan. Each conclusion is tied to a specific part of the process under review. The number of risks is not predetermined. If there are no launch blockers, the report states what was reviewed and the boundaries within which the conclusion applies.
The review is a standalone service with a concrete deliverable. You keep the report and can have your team, another contractor, or me implement the recommendations under a separately agreed scope.
The fee depends on the process and the amount of material. An automation reliability review starts at $400, an AI product pre-launch review at $600, and a payment journey review at $1,200. We agree the exact fee in writing before work begins.
The report is normally ready within 3–5 business days after I receive the agreed materials. Implementation timing is estimated separately once the scope, dependencies, and acceptance criteria are clear.
You receive a record of what was reviewed, any limitations found, and a conclusion for the agreed scenario. I do not invent issues to reach a quota or claim that a limited materials-based review proves the whole system safe.
Formal smart contract audits, penetration testing, certification, and legal opinions on AML, MiCA, or other regulation. I also do not manage client funds, give investment recommendations, promise returns, or guarantee a particular level of system availability.
No. A system overview, process diagram, settings with secrets removed, sample event logs, and screenshots of operating metrics are normally enough. A diagnostic review does not require passwords, real keys, or access to the live system. If access is needed for a separate implementation phase, we agree its purpose and duration in advance. Permissions should be limited to the minimum required and remain revocable at any time.
Client materials remain confidential. Public examples use anonymized information without closed-project names or customer data. If an NDA is required, we can agree and sign it before sensitive materials are transferred.
Your product, source materials, and data remain yours. My deliverable is the report and recommendations within the agreed scope. Rights relating to later implementation and use of its outputs are documented before that work begins.
I personally perform the reviews and engineering work described on this site. If a task requires a separate specialty, such as a formal security audit, substantial frontend development, or design, it is not included automatically. We agree the participants and separate scope in advance.
I speak Russian fluently. For English calls, I can use the real-time interpretation system I built. Key agreements about scope, fees, and responsibilities are always confirmed in writing. Documents and correspondence are available in English or Russian.
UTC+3. My working day overlaps well with Europe and the CIS, and with part of the US East Coast day. We agree specific meeting times in advance.
Bank transfer, payment services, stablecoins, and cryptocurrency are available. We agree the currency, method, and payment schedule in writing before work begins.
An external review gives the team a map of risks and priorities for one important process. Your developers keep their system knowledge and can implement the recommendations themselves. I examine failure modes and process boundaries without judging people or replacing the team.
Usually not. The review separates launch blockers from improvements that can wait. I prioritize risks such as duplicate charges, data loss, leaked keys, uncontrolled API costs, and failure to recover after an incident. I recommend a rewrite only when local changes cannot solve the agreed problem.
A separate review makes sense if the system handles money or personal data, or if a real-time process matters. If the risk and consequences are limited and the work would not be proportionate, I will say so during the first 15-minute conversation.
The site describes specific outcomes from my engineering work: more than 100 million requests per day in a payment core, monitoring of more than 3 million wallets, more than 10,000 concurrent WebSocket connections, and a 90% reduction in blockchain transaction fee costs. These metrics belong to individual implemented systems and are not promised outcomes of a review.
You can give the report to your team or another contractor. If you want my help, we separately agree the implementation scope, timing, responsibilities, access, and acceptance criteria. Continuing with me is optional.
Yes. After a review or implementation, we can discuss support for a critical part of the system or fractional engineering and technical leadership. The included work, response times, and exclusions are documented separately. The format does not include 24/7 on-call coverage by default.
Message me on Telegram with what should happen, what happens instead, and how it affects the business. In the first 15-minute conversation, we establish whether the task fits my expertise, what materials are needed, and the boundaries of the work.
