What we build

Tell us the problem — we engineer the system

LesterTechLabs is a remote-first software and AI labs company. Start with one request; we scope custom apps, products, APIs, automation, and cloud — then deliver through a portal you can follow end to end.

01

Custom software

Web platforms, internal tools, and business systems — architecture through production handoff.

02

Product & SaaS

Multi-tenant products, billing, admin, and portals — the craft behind LaundryOps, LegalTranscribie, and Lester PaaS.

03

APIs & integrations

REST and GraphQL, payment rails, WhatsApp, and third-party systems wired cleanly into your stack.

04

AI & automation

LLM features, RAG, document intelligence, and agents built for production — not demos.

05

Cloud & DevOps

AWS, Azure, GCP, or Lester PaaS — Docker, CI/CD, monitoring, and managed operations.

06

Mobile & enterprise

Cross-platform apps, ERP/CRM workflows, and process automation that stays reliable at scale.

How engagement works

From request to paid delivery — one clear path

No black-box process. You submit once, get a reference code, and move through negotiation, payment, delivery, and invoices inside the LesterTechLabs portal.

  1. 01

    Submit a request

    Guest or signed-in wizard. Describe the work, attach context, and receive an instant reference code.

  2. 02

    Track status in the portal

    Sign in with the same email to follow progress, messages, and milestones — no chasing status updates.

  3. 03

    Negotiate in the open

    Transparent scope and pricing discussion before you commit — align on approach, timeline, and budget.

  4. 04

    Pay securely

    Stripe or M-Pesa when you’re ready. Payments stay tied to your request and invoice record.

  5. 05

    Review delivery & revisions

    Download deliverables, request revisions when needed, and close the loop with a clear review step.

  6. 06

    Invoices by email

    Branded invoices land in your inbox — ready for finance, audit, and your own records.
