Building Scalable
Digital Solutions
Hello — I'm Lucas Heredia. Software Engineer
With experience leading teams, migrating platforms, and optimizing AI-driven workflows. I focus on delivering scalable, maintainable systems that bridge business strategy with technical execution. Currently diving deeper into AI agents and spec-driven development.
What stands out
Scalable e-commerce platform for a fashion brand with full shopping experience, payment integration, and marketing capabilities.
Customizable e-commerce with real-time product simulation for embroidered garments, reducing friction and lifting conversion.
E-commerce specialized in accessories for runners: Garmin mounts, race bib holders, and more — built for a niche sports brand.
Where I've worked
Currently building AI-first products for clients, integrating LLM agents, MCP servers, and retrieval pipelines into production web and mobile applications. Working with React, Next.js, React Native, TypeScript, and Node.js alongside frontier AI tooling like LangChain, LangGraph, OpenAI, Claude, and Gemini. Applying spec-driven development, context engineering, and evaluation practices to ship reliable AI features. Managing architecture, cloud infrastructure (AWS, Firebase), VPS deployments, and end-to-end delivery for multiple clients.
Unblocked a critical module stalled for over 6 months, enabling the release of 3 key investors. Led database migration and restructuring, managed deployments across all environments. Optimized AI agents through spec-driven development (MCP + rules). Automated workflows and contributed to infrastructure and design decisions.
Participated in client acquisition, presenting technical solutions and closing deals. Led end-to-end delivery of digital products from requirements to production. Designed development workflows, selected tech stack, and defined best practices. Bridged business strategy with technical execution.
Handled VPS deployment, server configuration, and domain management. Developed and optimized web apps using Next.js with SSR and SSG. Refactored project structure focusing on code standardization and component reusability. Met delivery deadlines while improving workflows and team efficiency.
Worked on multi-repo projects for international clients. Documented entire Google Cloud project at technical and product levels. Proposed and implemented new technologies (Zustand, GraphQL, Nivo). Developed Django endpoints with thousands of active users. Led migration of a legacy Python platform to React.js and GraphQL.
Implemented real-time notification system using AWS SNS and WebSockets. Developed infinite scroll with GraphQL for optimized performance. Documented Docker and Windows OS setup in Confluence.
