I am a Senior Backend and AI Infrastructure Engineer specializing in designing, implementing, and hardening stateful multi-agent orchestration systems, robust tool-calling workflows, and secure RAG pipelines using Golang. By combining Go’s high-concurrency power with cloud-native AI frameworks, I bridge the gap between experimental AI concepts and blazing-fast, enterprise-scale software. My expertise directly solves the core challenges of building scalable, observable, and cost-effective agentic systems: 🐹 Core Golang & Platform Engineering • High-Concurrency Go: Architecture of ultra-low latency backend systems utilizing goroutines, channels, and robust worker pools. • Solid API Engineering: High-performance microservices, secure auth flows, complex third-party integrations, and rigid error handling. • Stateful Distributed Systems: Deep experience managing data, state, and caching layers via PostgreSQL, Redis, and DynamoDB. • Asynchronous Processing: Building event-driven architectures with queues (SQS/SNS), background background jobs, and multi-step transaction retries. 🤖 AI Agentic Workflows & Orchestration • Stateful Multi-Agent Design: Expert in building reliable routing, fallbacks, and human-in-the-loop validation using custom Go orchestration layers, LangChainGo, or state machines. • Deterministic Tool Use: Implementing rock-solid function calling and structured JSON outputs to tightly connect LLMs to your core APIs. • Production Optimization: Extreme fine-tuning of systems for latency, token efficiency, hallucination mitigation, and model selection trade-offs. ☁️ AWS & Bedrock Infrastructure • Native AWS Bedrock Integration: Highly efficient model invocation, Guardrails, Knowledge Bases, and Agent orchestration utilizing the AWS SDK for Go. • Cloud-Native Deployments: Designing secure, scalable infrastructure utilizing Lambda, ECS/EKS, S3, API Gateway, and strict IAM policies. • Production Observability: Implementing deep tracing and logging via CloudWatch to audit agent execution steps, runtimes, and api costs. 🔍 Advanced Retrieval (RAG) & Context Engineering • Designing context-building pipelines with optimized chunking and semantic embeddings. • Implementation of hybrid vector search and metadata filtering to ground responses safely in enterprise data. Whether you need to architect a new multi-step AI workflow from scratch, optimize a slow python/node pipeline for massive speed and lower compute costs, or integrate complex data into a secure AWS Bedrock environment, I deliver clean, tested, and highly maintainable Go code. Let’s connect to discuss your agentic workflow goals and how we can bring them to production reliably.

I scrape the “unscrapable.” I automate the repetitive. I build systems that run themselves. Before I touch the code, I dig into the problem. Most scraping and automation jobs fail because someone skipped the research phase. I don’t. Web Scraping & Data Extraction • Handling complex anti-bot protections (Cloudflare, DataDome, PerimeterX) • Browser fingerprinting and stealth automation • Large-scale extraction across millions of records • E-commerce price monitoring • Proxy rotation and CAPTCHA solving Browser Automation • Selenium, Playwright, nodriver • Daily scheduled tasks (logins, form submissions, data collection, reporting) • Headless and headful workflows depending on what the site demands • Long-running automations that survive site changes Automation & Scripting • Business process automation • Scheduled tasks and cron jobs • Data pipelines and ETL • Custom scripts that fit your actual workflow WordPress & WooCommerce • Custom plugin development, including plugins published on WordPress for clients • Recent client work: ShopWriter, an AI content generator plugin for WooCommerce • Data import/export scripts • Product feed automation • WooCommerce ↔ Shopify migrations Chrome Extensions • End-to-end extension development (Manifest V3) • Backend integration with FastAPI and REST APIs • Live example: Bazenda for Chrome, my own extension on the Chrome Web Store Backend Development • Python, FastAPI, PHP • PostgreSQL, MySQL • REST API design I also build complete systems from scratch. Bazenda is the clearest example: a US fashion discovery app I built solo, with visual search, AI recommendations, and price tracking across dozens of brands. Live on iOS, Android, and Chrome. One thing I won’t do is tell you what you want to hear. If your project isn’t a good fit for me, or if there’s a simpler way to solve it, I’ll say so upfront. Saves both of us time. Message me with your project. I’ll take a real look and give you an honest answer.
