Other needs
When delays, growing traffic or complex data processing hold your product back
Capacity and latency, technical planning, trading software and data processing. We discuss your problem, the intended result and the boundaries of the engineering work.
I work on a specific engineering problem: understanding a failure, preparing a system for growth or defining the next phase of development. Start with the business problem.
Message me on TelegramYour service slows down or loses connections
For communication products, live streaming, marketplaces and device management platforms. Get in touch when growing traffic causes delays, dropped connections or lost events.
I assess how to distribute load, recover after a failure and verify that the system can handle the expected volume. The review includes recommendations for measuring latency and planning load tests.
On a live speech translation platform, I built media session isolation that supported more than 10,000 concurrent WebSocket connections. Reusing results in the AI provider integration brought latency below 250 ms and cut provider API costs by 40%. On a device management platform, the message bus I developed reached peak throughput of up to 60,000 requests per second.
You need to know what to change before scaling
For founders, investors and teams assessing a product's technical constraints or deciding which development work should come first.
I assess the system, separate urgent risks from accumulated technical issues, and prepare a plan for the team. Work can include technical due diligence before an investment decision and ongoing participation as a technical leader. Ongoing support usually begins after a review or implementation phase.
On a device management platform, I helped design architecture with capacity headroom for a tenfold increase in the device fleet. I also optimized a PostgreSQL database with more than 60 tables and 8 hierarchy levels. Across engineering and mentoring work, I have conducted more than 100 detailed code reviews.
Your trading software needs explicit, testable rules
For teams working on order execution, historical strategy testing, market data processing and software risk controls.
I build software and infrastructure with explicit execution rules, pre-trade checks and system monitoring. I do not offer management of client funds, investment recommendations or promises of returns.
As the lead engineer of a trading and analytics product, I built a signal scoring mechanism that reduced false signals by 50% and implemented 15 pre-trade risk checks. These results describe specific system mechanisms, not strategy returns.
Catalog and file processing keeps needing manual restarts
For e-commerce, publishers and media businesses that collect data, standardize it and generate finished files. Get in touch when standard tools no longer cover the work and failures force processing to start over.
I design processing systems with tracked stages, recovery from saved progress and predictable storage requirements.
On a publishing project, I was responsible for the complete process from data collection to finished files, handling more than 4,000 catalog items. Parallel processing increased throughput tenfold. Checkpoints and restarts without duplicate work eliminated progress loss during failures. Media optimization reduced storage requirements by 50% while preserving typography quality.
How to begin
Describe what is getting in the way and the result you need. The first conversation establishes whether the task fits my expertise. For a diagnostic review, we select one important process and agree the work, fee, timing and materials.
Prepare a description of the problem and available diagrams, example events and operating metrics with secrets removed. If your developer holds the technical materials, they will need to help prepare them. You do not need a technical specification for the first message.
A diagnostic review establishes the plan for further work. Formal security audits, certification and legal opinions are excluded. Data collection remains subject to site terms, personal data requirements and rules on messaging.
The examples above describe my contribution to individual projects. Client materials remain confidential.
Technical details for your developer
- Real-time systems: connection lifecycle, backpressure, fan-out, recovery, caching, monitoring and load test planning.
- Architecture and technical leadership: Architecture & Scale Audit, Technical Due Diligence, code review and technical specifications.
- Trading infrastructure: execution engine, backtesting, risk guards, market regime classification and order book analytics.
- Data processing: normalization, file generation, checkpoints and idempotent restarts.

Message me on Telegram with what you want to improve. We will start with a 15-minute call. You do not need to choose a technical service name.
Frequently asked questions
Outcomes and fees
What exactly will I receive after a diagnostic review?
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.
Why is the diagnostic review a separate paid service?
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.
How much does it cost?
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.
How long does a review take?
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.
What if you find no critical problems?
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.
What is excluded from a diagnostic review?
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.
Access and confidentiality
Do you need production access?
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.
How do you handle confidential material?
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.
Who owns the product ideas and materials?
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.
Working format
Do you work alone or with a team?
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.
What language do you use for calls?
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.
What time zone do you work in?
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.
How can I pay?
Bank transfer, payment services, stablecoins, and cryptocurrency are available. We agree the currency, method, and payment schedule in writing before work begins.
Fit for your task
We already have developers. How does an external review help?
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.
We built the product with AI tools. Will everything need rewriting?
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.
Our project is small. Is a review worthwhile?
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.
What evidence supports your experience?
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.
After the review
What happens after the diagnostic 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.
Can we arrange ongoing support?
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.
How do we start?
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.
