CV · Developer

Timothy Essuman

Full-stack TypeScript. Next.js and NestJS in production, PostgreSQL underneath, React Native in the field. Five years in procurement and supply chain before the code, which is why I ask what the work actually is before I ask what to build.

Strengths

  • Designed and shipped an eight-module ERP in daily use by 50+ staff across a factory and farm.
  • Next.js App Router, NestJS, code-first GraphQL, PostgreSQL, Tailwind v4.
  • Offline-first mobile capture with background synchronisation, for work where the signal drops.
  • Role-based access control, audit logging, and event-driven notifications across eight modules.
  • Domain fluency in procurement, inventory and production that does not need explaining first.

Experience

  • GreenEarth Agro Industries

    March 2026 to present

    Factory Manager · Ajumako, Ghana

    • Run the daily operation of a palm kernel processing facility: procurement, production, labour and buyers.
    • Own procurement of palm kernel seed, the facility's primary raw material, from sourcing through receipt and payment.
    • Plan and supervise daily production runs, optimising throughput against raw material, labour and plant capacity.
    • Maintain the supplier master record and the buyer register, and report a daily snapshot of factory activity to executives overseas.
    • Operate, every day, the ERP I designed and built for this facility, which is the tightest feedback loop a developer can have on their own system.
  • GreenEarth Agro Industries

    August 2025 to March 2026

    Technology Project Coordinator · Ajumako, Ghana

    • Designed and built an eight-module ERP replacing Excel reporting across factory and farm.
    • Built a farmer-facing mobile application connecting 100+ smallholders to the processing facility.
    • Reduced operational data discrepancies by 80% and recovered roughly 20 hours a week of manual reporting.
    • Coordinated with UNICEF StartUp Lab mentors to secure prototype funding and technical support.
  • Omnisoft Africa

    April 2025 to May 2025

    Product Development Intern, MEST Africa Immersion · Remote

    • Built a property maintenance request system for the ImmoAsk marketplace, with role-based flows for landlords and tenants, image upload, and a live preview that updates as the form is filled.
    • Architected a dynamic inventory system generating unlimited itemised entry and exit records, with per-item image compression and state preserved across navigation.
    • Integrated posting to four social platforms behind one abstraction layer: OAuth 2.0 linking, token refresh, per-platform adapters and content formatting, rather than four parallel integrations.
  • ESOKO, Ghana National Household Registration

    October 2022 to February 2023, and October to December 2023

    Team Supervisor · Ajumako and Breman Asikuma, Ghana

    • Supervised twelve enumerators across two field seasons at 100% data-quality compliance.
    • Reconciled daily returns against structural listing datasets, catching anomalies before they reached the data-quality team.
    • Ran the computer-assisted interviewing tooling in the field and fixed it there, which is where I learned what happens to software when the signal drops.
  • Fresh Zone Fruits and Vegetables

    January 2020 to June 2022

    Procurement Manager and Finance Manager · Ashaiman, Ghana

    • Reduced procurement costs by 20% through vendor negotiation and cost modelling.
    • Owned the end-to-end procurement lifecycle, from needs assessment through contract management, which is the process the ERP procurement module was later modelled on.
    • Held supplier relationships across perishable categories, where a late delivery is a write-off. That constraint is why the inventory module tracks batches rather than totals.
