Junior Full-Stack Developer

Slaab.ai

May 2025 - July 2025

Remote, India

Worked on an internal, pre-launch AI-powered SEO platform intended for B2B customers, focused on automated website audits, keyword research, and content analysis. Contributed primarily to backend systems and agentic workflows, while also shipping frontend features and performance improvements during active development.

Key Achievements:

Designed and implemented the backend architecture for an AI-driven SEO audit system during early-stage product development.
Built agentic LLM workflows using Mastra.ai to coordinate crawl analysis, SERP evaluation, audit reasoning, and actionable fix generation.
Integrated DataForSEO, FireCrawl, and Puppeteer to collect crawl data, keyword intelligence, and page-level signals for downstream analysis.
Implemented an async, job-based execution model using BullMQ to safely handle long-running audits with retries, idempotency, and failure isolation.
Used PostgreSQL as a persistent store for job state and intermediate results to support retries and client polling.
Developed REST APIs for initiating audits and querying progress and results during internal testing.
Reworked an existing UI by introducing structured client and server state management, reducing render overhead and improving responsiveness.
