About

I build production-ready web products across backend architecture, AI workflow orchestration, real-time systems, authentication, and deployment.

At AlphaTales, I co-built an AI-native project planning platform from the ground up. The product converts raw ideas into validated requirements, deep research, PRDs, architecture plans, task breakdowns, and agent-ready Dev Packs for development teams.

My strongest work sits at the intersection of FastAPI backends, MongoDB data modeling, LangGraph / Azure OpenAI workflows, Next.js product UI, and event-driven execution with Dapr, RabbitMQ, and Socket.IO.

Open to local, remote, and international Full Stack Engineer, Backend Engineer, Founding Engineer, and AI SaaS Product Engineer roles.

Featured Projects

AlphaTales - AI-Native Project Planning Platform

Commercial product co-built from the ground up for idea validation, planning, and agent-ready development handoff.

Problem: Product teams often move from rough ideas to engineering work without enough validation, research, technical clarity, or structured task planning.

Approach: Built production backend and AI workflow systems that turn ideas into validated requirements, PRDs, stack recommendations, tasks, and downloadable Dev Packs. Integrated FastAPI, MongoDB, LangGraph, Azure OpenAI, Dapr Pub/Sub, RabbitMQ, Socket.IO, and WorkOS authentication.

Result: Shipped a real AI SaaS product with structured project planning flows, real-time workflow execution, and developer-ready outputs.

Refacta - AI Code Intelligence Platform

Engineering tool for repository analysis, code understanding, and structured refactoring workflows.

Designed backend workflows for codebase ingestion, file analysis, structured outputs, and developer-facing AI assistance. Focused on reliable API contracts, orchestration, and practical engineering workflows.

clawd - OpenClaw Agent Workflow

OpenClaw-tagged agent workflow for prompt-first lead intelligence with JSON auditability and HubSpot handoff design.

Built an agent-style workflow that structures lead research, validates intermediate outputs, and keeps execution auditable through JSON artifacts. The project demonstrates how prompt-first agent systems can move from research to CRM-ready handoff.

InFit - Nutrition & Fitness Mobile App

Mobile-first nutrition and fitness app focused on practical meal planning and user-friendly tracking.

Built Flutter screens, app flows, and product logic for a consumer health experience. The project strengthened my mobile UI, product thinking, and cross-platform development work.

Focus - OCR Accessibility Project

Final-year academic project for reading text from images and improving accessibility.

Built an OCR-based workflow to extract text from images and support assistive reading use cases. This was my undergraduate final-year project, so I present it as academic work, not commercial production work.
