I am a Java developer with over 14 years of experience building full stack applications, enterprise systems, and SaaS platforms 🚀
My focus 🎯 is on using Java, Spring Boot, React.js, PostgreSQL, and AWS to deliver reliable, scalable software. As a Java developer, I have delivered dozens of projects across industries and use cases.
My backend work is built entirely with Java. I create secure APIs and microservices using Spring Boot. I have deep experience in system architecture, backend performance, and database design. Every project I take as a Java developer is written with clean, maintainable Java code. I know how to structure services that scale.
As a Java backend developer, I have built and maintained systems for high-load traffic, third-party integrations, and complex business logic. I manage full backend pipelines, from architecture and development to deployment and monitoring. I use Spring Boot and follow best practices every Java developer should apply.
I also work as a full stack Java developer, connecting Java backends with React.js and JavaScript frontends. I create dashboards, user interfaces, and admin tools that are fast, stable, and fully integrated. I know how to deliver full stack features without bottlenecks.
I have led teams as a senior Java developer, mentoring other developers, reviewing Java code, and improving team performance. My clients rely on me not just for development, but also for decisions about architecture, data structure, and deployment strategy. As a Java developer, I care about the full picture.
In most projects, I take the role of a Java spring developer and own the backend infrastructure. I work with Docker, PostgreSQL, REST APIs, and cloud services. I often work independently, taking full responsibility for both backend and frontend parts as a full stack developer.
Being a professional Java developer means I deliver production-ready code, meet deadlines, and communicate clearly. I work well with teams or as a solo contributor. My background as a Java backend developer and Java spring developer allows me to adapt to different project needs.
If you need a Java developer who can work on backend systems, full stack features, or cloud-based platforms, I am ready to help. Whether you need a senior Java developer, a Java backend developer, or a reliable full stack Java developer, I can take your project from idea to production.

Hi, I am a software developer with deep experience in compiled languages, primarily Rust, Java, and Kotlin, with a strong focus on systems that require big data processing, real-time data pipelines, and low-latency execution. I design and build distributed backends deployed across cloud platforms such as AWS, GCP, and self-hosted infrastructure. My primary expertise lies in the FinTech, IoT, and eCommerce domains, with a growing focus on high-performance trading infrastructure built in Rust. I remain open to exploring and contributing to other industries that demand innovative, data-driven applications.
📈 Funding Rate Arbitrage System (Recent)
Currently building a low-latency cryptocurrency funding rate arbitrage system that operates across multiple centralized and decentralized venues. Originally prototyped in Java and Kotlin, the system has been completely rewritten in Rust to meet stricter latency and reliability requirements. Technologies used:
🔹 Rust at the core for execution-critical paths, including order routing, position reconciliation, and venue connectors where tight latency budgets and predictable performance matter most
🔹 Native integrations with Binance, Bybit, Hyperliquid, and Kraken, covering both perpetual futures and spot legs
🔹 Real-time funding rate aggregation, slippage modeling, fee accounting, and risk management to identify and capture cross-venue spreads
⚡ IoT Platform
I have worked on a distributed IoT platform in AWS IoT with numerous integrations and a complex architecture. Transitioned the platform from Telit to AWS IoT Core.
Technologies used:
🔹 Java Spring Boot with AWS ECS to develop a scalable message-processing microservices pipeline
🔹 Dagger 2 with AWS Lambda for efficient dependency injection in serverless applications
🔹 Node.js (TypeScript) with AWS Lambda functions to implement specific integrations and enhance functionality
🚀 FinTech Trading System
Developed a robust, scalable trading system capable of handling dozens of symbols across multiple accounts and brokerages.
Technologies used:
🔹 The trading system is being developed using Java and Kotlin within a Spring Boot microservices architecture
🔹 Apache Kafka integrated to support the backtesting of extensive datasets
🔹 To complement the backend functionality, I developed a simple UI using React and Redux, enabling users to interact with the system
🔹 Additionally, I researched and implemented a separate module written in Python, leveraging Deep Reinforcement Learning (DRL) techniques to explore advanced analytical capabilities
🔹 Integrations with OpenAI, Binance, Metatrader (via MetaApi), and Snapi news API (Crypto, Forex, Stocks) further enriched the system’s versatility and scope
🔹 For CI/CD processes, I utilized GitLab and Docker Compose with a Cloud Native Buildpacks (CNB) approach to streamline deployments and ensure efficient workflows
🛍️ E-commerce
Worked as a full-stack developer on various e-commerce projects, utilizing a wide variety of technologies and frameworks such as Java, SAP Commerce Cloud (Hybris), Spring, Apache Kafka, Hibernate, Hazelcast, Apache Solr, Kubernetes, React, and others.

I build production backends and scrapers that stay stable under load. I have migrated legacy systems, scaled APIs beyond 3,000 active users and 7M+ records, and built async data pipelines that process about 35,000 businesses in 9 minutes for roughly $0.25 in compute. I also build custom scrapers and crawling pipelines that turn dynamic and protected websites into structured data.
If you need someone who owns the backend and reliably extracts data from the web, I focus on performance, failure cases, anti bot systems, and cost from day one.
What I do, backend and APIs:
• Design and build REST APIs with FastAPI and Django, sync and async
• Architect microservices and background processing with Celery, Redis, Kafka, RabbitMQ
• Implement secure authentication with JWT, OAuth2, Argon2id, Supabase Auth, and role based access
• Optimize databases with PostgreSQL, SQLAlchemy, Supabase, Redis caching, and query tuning
• Integrate payments and webhooks with Stripe and other providers
• Deliver clean, tested, maintainable code
What I do, web scraping and automation:
• Build Python scrapers with requests, BeautifulSoup, Selenium, Playwright, Scrapy, undetected chromedriver, proxy rotation
• Handle both simple static sites and JavaScript heavy SPAs
• Bypass anti bot measures including Cloudflare, reCAPTCHA, hCaptcha and similar shields
• Use undetected headless browsers, 2captcha and CapSolver, and human like behavior to stay under the radar
• Scrape social platforms and restricted APIs, including Twitter via TwiKit and reverse engineered endpoints
• When there is no public API, extract data directly from the web
Asynchronous and scalable crawling:
• Use asyncio, aiohttp, asyncio.gather and asyncio.Lock for high volume scraping
• Crawl thousands of pages concurrently for e commerce price monitoring and large scale data collection
• Run long lived workflows with attention to efficiency and stability
Data processing and delivery:
• Clean and structure results into CSV, Excel, JSON, or direct database writes
• Integrate outputs into existing systems or dashboards
• Set up scheduled jobs so your data stays up to date
Applied AI and automation:
• Integrate OpenAI models such as GPT 4, GPT 4o mini, and GPT 5 mini into real products
• Build scoring, classification, and enrichment pipelines with Langfuse observability
• Add AI on top of ETL for cleaning, deduplication, routing, prioritization, and decision logic
• Implement chatbots, assistants, and business intelligence features powered by LLMs
• Embed GPT or custom models into scraping flows to classify content, auto fill forms, and make on the fly decisions
Selected results, influencer discovery API (Instagram, TikTok, YouTube):
• Migrated the service from Flask to FastAPI with a full sync to async refactor
• Recovered many previously broken endpoints and platforms
• Scaled the system to more than 7M database records and around 3,000 active users
• Added Celery task queues on Redis and GPT based content scoring with Langfuse monitoring
Selected results, Google Maps business intelligence backend:
• Processes about 35,000 businesses in 9 minutes using two level async parallelism
• Uses aiohttp, asyncio.gather and asyncio.Lock to avoid race conditions and keep the database stable
• Includes JWT and OAuth2 auth, Argon2id password hashing, a simple CRM for contacts and follow ups, and CSV export
Previous projects:
• Django REST backends with Stripe payments, webhooks, and admin tools
• Automation and scraping systems with Selenium, Playwright, undetected chromedriver, rotating proxies, 2captcha and CapSolver
• Backend automation for Web3 and social platforms with Discord and Twitter API integrations
Tech stack I am confident owning:
• Backend: Python 3.10+, FastAPI, Django, Flask, Django REST Framework
• Async and messaging: asyncio, aiohttp, Celery, Redis, Kafka, RabbitMQ
• Databases: PostgreSQL, Supabase, SQLite, SQLAlchemy ORM
• Auth and security: JWT, OAuth2, Argon2, Supabase Auth, cryptography
• AI and monitoring: OpenAI API, Langfuse, OpenTelemetry
• Scraping and automation: requests, BeautifulSoup, Selenium, Playwright, Scrapy, undetected chromedriver, TwiKit, 2captcha, CapSolver, proxy infrastructure
• DevOps: Docker, Docker Compose, GitHub Actions, Linux
You should contact me if:
• You need a backend for an AI product, SaaS platform, data heavy API, or large scale scraping system
• You want to migrate from Flask or legacy Django views to FastAPI or DRF with async where it actually helps
• You want AI powered scoring, enrichment, or automation built directly into your backend and scrapers
• You care about clean, maintainable code with tests, clear structure, and predictable behavior
If you have a concrete problem, send me a short description and I will tell you what I can build for it and how I would approach it.

Most AI projects fail for one simple reason:
They look impressive in a demo, but break when real users, real data, and real business workflows are involved.
I help businesses turn AI ideas into working products — not just prototypes. Whether you need an AI chatbot, RAG knowledge assistant, internal automation tool, SaaS MVP, AI agent, document processing system, or machine learning model, I build it with the full product in mind: backend, database, APIs, dashboard, deployment, and real user experience.
Currently based in 𝗛𝗮𝗻𝗻𝗼𝘃𝗲𝗿, 𝗚𝗲𝗿𝗺𝗮𝗻𝘆, I work with a product-first engineering mindset: clear communication, realistic timelines, and systems built for real business use, not just technical experiments.
I don’t just connect your app to 𝗢𝗽𝗲𝗻𝗔𝗜 and call it “𝗔𝗜.”
I design the complete system around your business problem.
Here’s what I can help you build:
𝗔𝗜 𝗖𝗵𝗮𝘁𝗯𝗼𝘁𝘀 & 𝗥𝗔𝗚 𝗞𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲 𝗔𝘀𝘀𝗶𝘀𝘁𝗮𝗻𝘁𝘀
Custom AI assistants trained on your PDFs, websites, internal docs, support tickets, product data, or company knowledge base. I build RAG pipelines using OpenAI, Claude, Gemini, LangChain, LangGraph, Pinecone, FAISS, Chroma, and other vector database solutions so your chatbot gives useful answers instead of generic AI replies.
𝗔𝗜 𝗔𝗴𝗲𝗻𝘁𝘀 & 𝗕𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻
I build AI systems that can handle repetitive workflows such as lead qualification, customer support, appointment booking, document review, reporting, CRM updates, email automation, data extraction, and internal task routing. The goal is simple: save time, reduce manual work, and make your team faster.
𝗔𝗜 𝗦𝗮𝗮𝗦 & 𝗠𝗩𝗣 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁
Have an AI product idea? I can help you turn it into a real MVP with authentication, dashboards, subscriptions, admin panels, backend logic, AI features, database structure, and deployment. I work with React, Node.js, FastAPI, Python, MongoDB, PostgreSQL, Docker, and cloud platforms.

I also build practical ML systems for recommendation engines, fraud detection, forecasting, NLP classification, sentiment analysis, OCR, data extraction, predictive analytics, and automation dashboards. I care about accuracy, but also about speed, cost, reliability, and whether the system can actually be used by your team.
