1. Founding Engineer

   RFQTrace

   Mar 2026 – Present

   Designed and built a multi-tenant RFQ and supplier quote management platform solo for small-to-mid-size manufacturers — the segment priced out of enterprise procurement suites. Live at rfqtrace.com.

   Key Achievements:

   • •Multi-tenant architecture with organisation-level data isolation and RBAC across 5 roles
   • •Offline-first caching (Dexie.js + Firebase Realtime DB) so the tool stays usable on low-connectivity plant floors and supplier visits
   • •Structured quote comparison on first-class fields — unit price, lead time, MOQ, payment terms — rather than free text
   • •One-link supplier portals that produce structured data instead of PDF attachments someone has to transcribe

   Key Achievements:

   • •Published 17 long-form engineering articles on RAG pipelines, OAuth patterns, multi-tenant architecture, and offline-first sync
   • •Designed and shipped mishhy.com — Astro with React islands, Firebase, full Playwright coverage and structured data

   • •Architected a reusable OAuth library covering 50+ SaaS integrations (Salesforce, Outreach, Salesloft, HubSpot, Segment, Gmail, Google Calendar), powering auth for 200 customer accounts and cutting new-integration build time by 60%
   • •Designed production AI workflows on OpenAI, Anthropic, and DeepSeek with structured outputs, function calling, and multi-step orchestration for sales lead generation, hiring signals, and lookalike account identification
   • •Delivered a production-ready frontend within 3 months and onboarded the first enterprise client; improved LCP by 40% through code splitting and asset optimisation, and established Cypress e2e testing, Sentry monitoring, and Segment/FullStory analytics

job-search-automation

Aggregates remote roles ($50k+, senior-level) from Greenhouse, Lever, and Ashby APIs, drafts a tailored cover letter per job using a multi-provider LLM abstraction (Anthropic, OpenAI, Gemini, DeepSeek, OpenCode, Ollama), and puts everything in one spreadsheet for review. Does not auto-submit applications — the automation is in aggregation and drafting, not submission.
