Inluck
Senior software engineer, techlead
Acted as a Tech Lead and Product Engineer for SaaS systems where uptime and latency directly impact revenue. Owned the entire architecture from scratch, made key technical decisions, and managed the full development lifecycle without a dedicated architecture team.
High-Load & Affiliate Network: Architected and maintained a network of 20+ high-load affiliate projects with strict SEO requirements. Handled traffic spikes up to 50TB per evening. To bypass framework overhead, migrated core routing and cloaking logic to Native PHP and NoSQL operations, maximizing RPS.
Security & Anti-Bot: Ensured production stability under constant DDoS and bot attacks. Set up multi-layered defense: custom WAF rules, bot honeypots, L7 filtering, and deep DDoS-Guard integration.
Web3 & Authentication: Engineered a custom NFT-based authentication system (token-gating) for secure access to internal B2B services. Developed and deployed smart contracts for access tokens, providing a decentralized, tamper-proof alternative to traditional login flows.
PostgreSQL & Data Engineering: Tuned databases for heavy reporting and telemetry. Resolved slow queries through profiling (EXPLAIN ANALYZE), table partitioning, and Partial/GIN indexing. Offloaded heavy analytics to ClickHouse.
Python Algo-Trading: Built backend infrastructure for crypto grid trading bots using Python and CCXT. Implemented reliable asynchronous data processing with Kafka. Solved message duplication and balance consistency issues (ensuring idempotency via database UPSERTs).
SEO Automation / Mobile: Developed a B2B product for automated behavioral factor (SEO) manipulation. Managed real mobile devices (Appium/Selenium) via proxy tunnels to emulate human behavior, bypassing active anti-fraud systems and captchas.
AI Tooling: Built and maintained OpenClaw — an internal autonomous AI agent for code generation and routine automation.
Tech stack: PHP (Symfony, Laravel, Yii2, Native), Python (Flask, CCXT), Node.js, Solidity, Web3.js, Ethers.js, PostgreSQL, ClickHouse, Kafka, Redis, NoSQL, Appium/Selenium, WAF, RabbitMQ.

Senior software engineer
Worked on the core backend of a fast-paced B2B financial SaaS. My main focus was making sure data synchronization between third-party systems was fast, completely fault-tolerant, and zero-loss.
API Integrations: Built and maintained high-throughput sync flows connecting e-commerce platforms with accounting software. Dealt heavily with external API rate limits, complex validation rules, and undocumented edge cases.
Data Reliability: Designed robust background processing pipelines. Focused on strict idempotency and safe retry mechanisms to guarantee that financial transactions were never duplicated or lost during network failures.
Performance Tuning: Profiled and fixed slow data processing paths. Tuned heavy MySQL queries, optimized indexes, and added caching layers to significantly reduce sync latency.
Production Support: Upgraded production observability by setting up better logging and alerts to catch desync anomalies early. Frequently jumped in to debug and resolve live production incidents.
Delivery & Quality: Guided the team's delivery process by leading code reviews, coordinating complex releases, and translating strict product requirements into stable technical features.
Tech stack: PHP 8, Node.js (TypeScript), Python, MySQL (Query Optimization), RESTful APIs, GraphQL, WebSockets, Webhooks, Redis (Queues & Background Jobs), OAuth2, E-commerce APIs.
