Techno Holt Labs is an engineering lab in Rawalpindi. One bench designs boards, writes firmware, and repairs hardware; the next ships mobile apps, cloud platforms, AI systems, and blockchain products. Same engineers, same standards, one point of contact.
Registered with SECP, Pakistan · Gulraiz Colony, Rawalpindi · since 2022
Techno Holt Pvt. Ltd. is a private limited engineering company registered with the SECP, running a lab in Gulraiz Colony, Rawalpindi since 2022. One side of the lab holds soldering and rework stations, bench instruments, and drawers of dev boards. The other holds the software benches — where the mobile apps, backends, and AI pipelines that ship with our hardware get built and reviewed.
We are deliberately structured: five head engineers, each leading a sub-team, covering embedded systems, PCB design, mobile, cloud, and AI. The engineer who reviews a schematic is on the same floor as the one writing the companion app — short handoffs, fewer translation errors, honest estimates. If part of an idea won’t survive contact with physics or a budget, we say so before you’ve paid for it.
OPERATING SCHEDULE
LAB VISITS BY APPOINTMENT · REQUEST ONE →
Hardware on CH1, software on CH2 — designed together, tested together, shipped together.
CH1 · HARDWARE
Bare-metal and RTOS firmware for ESP32, STM32, and nRF-class parts, plus embedded Linux and on-device AI on Raspberry Pi and NVIDIA Jetson — BLE, OTA updates with integrity checks, power management, and sensor fusion, debugged on real hardware.
C · C++ · RTOS · Embedded Linux · Edge AISchematic capture through layout, from simple 2-layer carriers to a shipped Ø35 mm 8-layer wearable. Design-rule-clean gerbers with full fabrication and assembly handoff packs.
2–8 layers · DRC-clean · Gerber X2First articles assembled and brought up in-house: board bring-up, fault isolation, firmware flashing, and a written report of what was measured — not what was hoped.
Bring-up · Rework · ValidationDiagnosis and rework for boards that misbehave, plus what production needs: bills of materials a contract manufacturer can order, test procedures, and assembly documentation.
BOM · Test jigs · Documentation
CH2 · SOFTWARE
Flutter and native apps shipped to both stores — including companion apps that pair over BLE with hardware designed three benches away. Auth, payments, offline sync, release engineering.
Flutter · iOS · Android · BLETyped frontends and APIs with automated tests, CI pipelines, and staging environments — plus the heavier back-office lifting: full ERP and CRM systems, desktop tools, and the workflows that run a company.
React · NestJS · ERP · CRMProduction AI beyond the demo: vision and speech pipelines, retrieval-augmented assistants, LLM-driven workflow engines — including a full video-assembly studio that runs without a GPU.
Vision · Speech · RAG · LLM agentsMultichain wallets with hardware-card signing, asset tokenization platforms, persistent-anchor AR SDKs with Flutter and React Native bridges, and the custom tools none of the above cover.
Wallets · Tokenization · AR SDKsThe one place numbering is earned — the process really is a sequence.
A call, then a written spec with milestones and a price. If something in the brief won’t work, this is where we tell you — not at month three.
Schematics and architecture reviewed by the leads who will build them. Hardware and software are designed together, not thrown over a wall.
Boards on the bench, branches in review. Every week you get progress you can hold in your hand or log into — not a slide deck.
Boards through functional test before they leave the lab; releases through CI and staging before they reach a user. Failures get logged and fixed, not explained away.
Gerbers, firmware, source, and deployment docs handed over in full. You own everything we made; nothing stays hostage in our repo.
Eleven of 100+ delivered projects. Anonymized by policy — the engineering is real, the names stay in the lab.
A passive long-range system that detects, classifies, and localizes sound sources using AI/ML — emitting nothing itself.
Multi-sensor acoustic arrays with beamforming, an edge-AI classification pipeline, weatherized sensor hardware, and secure telemetry that lets networked units cooperate to localize a source in real time.
Client & product names withheld by policy.
An ultra-compact wearable that captures, streams, and powers itself — the entire system, from bare board to cloud.
A dense multilayer PCB with a wireless SoC, microphones, and battery management; embedded firmware; a companion mobile app for setup and status; and a cloud audio backend — one team, every layer.
Client & product names withheld by policy.
The control software for a therapeutic wearable used in regulated clinical research — where a dropped session is a protocol violation.
Reliable wireless device control with safety interlocks, session integrity with automatic recovery, lock-screen treatment timers, auditable logging, and integrity-checked over-the-air firmware updates.
Client & product names withheld by policy.
A mobile-first platform that tokenizes verified physical assets into stable digital value, wrapped in everyday banking.
Production-grade banking foundations — authentication, KYC, payments — rebuilt on a modern typed stack, with an engineering roadmap that reconciles an ambitious tokenization vision against operational reality.
Client & product names withheld by policy.
A marketplace connecting consumers, merchants, and couriers — three apps, one backend, one shared AI brain.
Ordering, scheduling, wallets, loyalty, and payments across three mobile apps, plus a retrieval-augmented AI assistant with voice — its money-moving calls proxied server-side so no credentials ever ship in an app.
Client & product names withheld by policy.
A developer toolkit that pins persistent, interactive AR content to real-world locations — and keeps it there.
Native spatial-anchor layers for both mobile platforms with cross-framework bridges, anchor persistence and retrieval, and a developer console for app registration, credentials, and usage management.
Client & product names withheld by policy.
A self-custody wallet where private keys can live on a tap-to-sign hardware card instead of inside the phone.
Multichain wallet architecture — hot and cold accounts, swaps, gasless transactions, portfolio tracking — with contactless hardware-card key derivation and transaction signing, delivered across mobile, backend, and DevOps.
Client & product names withheld by policy.
For a developer-run housing community in Pakistan: a system that makes property papers impossible to tamper with quietly — and grew into the community’s full ERP.
Tamper-evident verification hardware at the records desk, desktop and mobile apps for staff and residents, and the operational core behind them: plots, ownership transfers, dues, approvals, and a complete audit trail in one system.
Client & product names withheld by policy.
The operating system for a Pakistani audit firm whose clients include airports and pharmaceutical manufacturers — where a lost finding is a liability.
Engagement planning, field checklists, evidence capture, findings and corrective-action tracking, report generation, and role-based review flows — one traceable system from first site visit to signed report.

Read it like a datasheet — because that's how we'd want to be evaluated.
