Building solutions. Solving problems. Learning along the way.

I'm an engineer who enjoys figuring things out - understanding the problem, thinking through the options, and turning ideas into practical solutions.

About

I enjoy figuring things out.

For me, technology is less about using a particular tool and more about understanding a problem and finding a solution that actually makes sense.

Over the years, I've worked across cloud, CMS, automation and GenAI, while getting more involved in solution design, technical planning and stakeholder discussions.

I enjoy moving between the technical details and the bigger picture: what we're trying to achieve, what the constraints are and how an idea becomes something practical.

I learn by building and experimenting, and I like sharing the practical lessons that become clear along the way.

How I approach a problem

Approach

How I Think

I usually prefer to start with the problem rather than the technology.

  1. 01

    Understand

    What are we actually trying to solve?

  2. 02

    Ask

    Who is this for? What are the constraints? What does success look like?

  3. 03

    Design

    What are the possible approaches, and which one makes sense?

  4. 04

    Build

    Only then do I start thinking deeply about implementation.

Good engineering isn't only about building something correctly.

It's also about making sure you're building the right thing.

Focus

What I Work On

The areas where I spend most of my time thinking, building and learning.

  1. Software Engineering & Problem Solving

    Understanding the real constraint and turning clear requirements into practical software.

  2. Solution Design

    Breaking down requirements, constraints and trade-offs before choosing an approach.

  3. Generative AI

    Testing where GenAI and AI agents solve a real problem, and where they do not.

  4. Technical Leadership

    Creating clarity, supporting teams and taking ownership when the path forward is not obvious.

Case studies

Selected Work

A few things I've built and worked on.

Request a demo

Primary case study

QueryPilot - Natural Language Database Assistant

Problem

A conversational database assistant that converts natural language questions into schema-aware SQL queries.

Approach

A schema-aware workflow uses database context to generate SQL, with human review before execution.

What I built

I designed the LangGraph workflow and built the system across a FastAPI backend, PostgreSQL schema introspection and a React frontend, with human review before query execution.

Workflow

  1. 01Natural Language
  2. 02Understand Request
  3. 03Schema
  4. 04Generate SQL
  5. 05Human Review
  6. 06Execute

Technologies

  • Generative AI
  • AI Agents
  • LangGraph
  • LangChain
  • PostgreSQL
  • React
  • TypeScript
  • FastAPI

Why it matters

The human review step keeps generated SQL visible and reviewable before it reaches the database.

Additional work

Cloud Cost Management & Optimization

A cloud cost management solution focused on identifying opportunities to reduce cloud spend.

  1. Cloud APIs followed by
  2. Cost data followed by
  3. Analysis followed by
  4. Anomaly signals followed by
  5. Optimization opportunities

I worked on an AWS-based serverless architecture that connects to AWS, Azure and Google Cloud APIs, and explored anomaly detection for further cost optimization opportunities.
