How I Can Help

Whether you're starting fresh or improving an existing product, I can help you move forward.

Build an AI Feature

You want to add an AI assistant, semantic search, recommendation engine, or LLM-powered workflow to your product, built for production, not just a demo.

Build a New Product

You have an idea, requirements, or early design, and need someone who can turn it into a working web product end to end.

Develop Backend APIs & Microservices

You need clean APIs, scalable services, authentication, database design, and reliable integrations.

Improve an Existing Application

Your application exists but has bugs, performance problems, unclear code, missing features, or an outdated experience.

Create Dashboards & Analytics

You need a financial dashboard, reporting tool, admin panel, or data-heavy internal product for your team.

Support a Startup Team

You need a reliable engineer who can take ownership, lead, communicate clearly, and help move the product forward.

What I Do

From product development to AI integrations, I build software that solves real business problems.

AI & LLM Engineering

I build practical AI into real products, not just demos, from semantic search to conversational assistants.

  • LLM features (OpenAI API, LangChain)
  • Semantic search and embeddings
  • Retrieval-Augmented Generation (RAG)
  • AI chatbots and copilots
  • Natural-language-to-data interfaces
  • NLP pipelines and AI content workflows
  • Recommendation systems

Backend & Microservices

I design backend systems that are organized, scalable, and easy for teams to build on.

  • REST API design and integrations
  • Scalable microservices
  • Authentication and authorization
  • Database design and optimization
  • Background jobs and scheduled tasks
  • Payment and subscription workflows
  • Role-based access control

Full-Stack Product Development

I build complete web products from frontend interfaces to backend APIs, databases, and deployment.

  • Next.js, React, and Flutter
  • TypeScript and JavaScript
  • Python, FastAPI, Django, Litestar
  • Node.js, Go, Express, NestJS
  • PostgreSQL, MongoDB, MySQL
  • Docker, AWS, GCP, CI/CD
  • Dashboards and data visualization

Engineering Leadership & Teaching

I lead teams, mentor engineers, and teach the fundamentals that make great developers.

  • Leading engineering teams of 10+
  • Data Structures & Algorithms teaching
  • Technical mentorship and reviews
  • Architecture and technical decisions
  • Feature planning and debugging
  • Clear technical communication
  • Documentation and onboarding

Process

How I Work

I care about clear communication, practical decisions, and shipping useful work.

When I join a project, I start by understanding the product, the users, the existing codebase, and the most important business problem. From there, I break the work into manageable pieces and focus on solutions that are reliable and easy to maintain.

I am comfortable with early-stage startups, established teams, and solo founders who need a technical partner to move faster, and I bring a leadership mindset from years of leading and teaching engineers.

I value

  • Clear requirements
  • Honest communication
  • Clean and maintainable code
  • Fast feedback loops
  • Practical solutions over complexity
  • Products that solve real problems
