I’m a Principal Full Stack Engineer and Software Architect with 15+ years of experience designing and scaling SaaS, AI, Fintech, Healthcare, and E-Commerce, and now evolving those platforms with AI-driven capabilities. I design architectures where LLMs, embeddings, and data pipelines work alongside robust APIs, enabling automation, insight generation, and conversational interfaces inside enterprise products. I’ve worked across the full company spectrum: • Startups that needed rapid MVPs, lean architectures, and fast iteration • Scaleups where performance, stability, and automation become critical • Enterprises with complex compliance, multi-team collaboration, and long-term architectural planning My Teck Stacks & Specializations: • Frontend: React, Next.js, TypeScript, Tailwind, Material UI • Backend: Node.js (Express, Nest.js), Python (FastAPI, Django), Java, C#, REST, GraphQL, WebSockets AI & Data: LLMs, RAG pipelines, embeddings, vector DBs, LangChain, LlamaIndex, ETL/ELT • Cloud & DevOps: AWS, Azure, GCP, Docker, Kubernetes, Terraform, CI/CD (GitHub Actions, Azure DevOps) • Databases: PostgreSQL, MySQL, MongoDB, Redis, DynamoDB • E-Commerce / CMS: Shopify, WooCommerce, WordPress (custom plugins, headless setups) I specialize in system and database architecture, designing platforms that handle complex business logic, high traffic, and real-time data at scale. I build distributed ecosystems using domain-driven design, microservices, and event-driven patterns, supported by resilient messaging workflows, serverless compute, and horizontally scalable APIs. From orchestrated services to autonomous event pipelines, and from optimized relational models in PostgreSQL/MySQL to high-throughput document and cache layers in MongoDB and Redis, I ensure every layer of the system is tuned for performance, reliability, and seamless growth. On the product side, I’ve built and optimized Shopify, WooCommerce, and custom WordPress solutions - integrating payments, automating operations, and improving conversions through smart architecture and automation. Clients value me for translating complex requirements into intuitive, high-performance applications while leading projects with transparency and efficiency. Every engagement is about long-term reliability. I ensure that what we build today continues to support tomorrow’s growth.

Are your employees spending more time fighting spreadsheets, copy-pasting data, and wrestling with off-the-shelf software than actually doing their jobs? ​When standard tools stop fitting your unique workflow, your business hits a ceiling. You start losing information, making mistakes, and wasting money on manual work. ​I build custom web applications, internal portals, and CRMs that adapt to your business — not the other way around. I don't just write code; I digitize your daily operations to eliminate chaos and help you scale without constantly hiring more managers. ​I know exactly why software projects fail: developers rarely try to understand the actual business. I take a different approach. For instance, when I built a custom CRM for a translation agency, I didn't just take a list of features. I dug into their daily bottlenecks, automated their task distribution, and delivered a system that saved them hundreds of hours. If you are tired of technical headaches and need a reliable system that actually works for your team, let's talk. ​Send me a brief message about the biggest bottleneck in your current process, and I'll let you know how we can fix it.
