Jonathan Sam Mathew — IT Manager · CRM & Infrastructure

(01) Profile

No predecessor.
No playbook. Built anyway.

USDC Global — Bangalore
Apr 2024 — Present

Joined as a Sales Executive. Left the sales floor having quietly become the company’s entire IT department — then made it official.

There was no CRM, no telephony, no server, no web presence and no one to ask. I evaluated, negotiated, architected and shipped every system the company runs on today — CRM, dialers, WhatsApp automation, production Linux servers, 15+ web properties and a private on-premise AI — while owning every vendor relationship end-to-end.

Now I lead a team of two that I recruited and trained from scratch, and I’m pursuing an MCA at JAIN University alongside the full-time role.

Now building: Course Finder (in-house automation) MCA @ JAIN · expected 2027

it-function.js

import { crm, telephony, servers, web, ai }
  from '@jsm/stack';

const itFunction = await buildFromZero({
  predecessor:   null,   // nobody before me
  documentation: null,   // wrote it myself
  team:          ['self'], // → now 3
  dataLoss:      0,      // every migration
  downtime:      0,      // 2 office moves, overnight
});

itFunction.scale();  // ongoing

(02) Experience

Three roles.
One company. ~18 months.

Promoted twice —
each time for systems I’d already built

Joined

Sales Executive

Hired to sell. Started fixing the technology nobody owned — and kept going.

Promoted

IT Administrator

Made it official: CRM, telephony, domains and workspace administration consolidated under one owner.

Apr 2024 — Present

IT Manager

Own all technology operations, every vendor contract, and a team of two direct reports.

EXP / 01

CRM Architecture & Migration

Evaluated Superleap CRM end-to-end before the company committed a rupee — workflows, roles, reporting, scalability
Designed the full architecture: department workflows, granular permissions, form logic, lead-routing automation
Executed the Sheets → CRM migration with zero data loss, plus a full mid-implementation rollback from a discontinued vendor
Sole point of contact post-launch: testing, edge cases, and hands-on training for every team

EXP / 02

Telephony & Communication

Deployed Ameyo and negotiated a policy exception — DID changes at 6 months, overriding their standard 1-year lock-in
Integrated MCUBE cloud telephony with the CRM for call tracking; negotiated pricing directly
Built progressive dialer flows, voice blaster campaigns and preferred-agent routing for conversation continuity
Onboarded AISensy as WhatsApp Business API provider with end-to-end automation workflows

EXP / 03

Web, Domains & Servers

Built 15+ pages and 2 lead-gen websites from scratch, every form wired straight into the CRM
Own the full domain portfolio: registrations, renewals, DNS, and SSL across all properties
Built the production Linux server from the ground up; migrated an agency-built site in-house with zero downtime — then fixed the bugs the agency missed

EXP / 04

Internal Tooling & On-Prem AI

Designed and built a complete IT ticketing system in-house — full lifecycle, automated email at every stage
Repurposed an idle CPU into a file server for Operations at zero hardware cost
Deployed a localized AI model on company hardware — private, on-premise, no third-party APIs

EXP / 05

Workspace & IT Operations

Set up Google Workspace for the whole org: domain verification, org units, permissions, reporting lines
Diagnosed and resolved recurring network downtime; implemented baseline access controls
Manage the complete IT asset inventory across every department; ran ActivityWatch + Wireshark monitoring when management needed it

EXP / 06

Vendors & Leadership

Sole point of contact for every technology vendor — contracts, renewals, integrations, escalations
Negotiated non-standard pricing and policy concessions across Ameyo, MCUBE, AISensy and others
Executed 2 full office relocations overnight — fully operational by morning, zero downtime; support remote offices from Bangalore

Student Portal — Learn Overseas

Sole developer · Full-stack · In production

Self-service portal connecting Superleap CRM to students and admins — application tracking, secure documents, role-based workflows
CRM-to-portal webhook pipeline: 8+ event types, field normalization at entry, 3-attempt exponential-backoff retry queue
Document system across 50+ types: version history, authenticated in-portal preview, bulk ZIP via single-use purpose-locked JWTs
Defense-in-depth auth: Argon2id, rotating refresh tokens, Zod validation, rate limiting, 3-role RBAC
17-stage lifecycle tracker giving students live visibility into their study-abroad journey
Own production ops on AWS Lightsail — Nginx, PM2, auto-renewing SSL, daily backups, live incident response

webhook-pipeline.js

// CRM → portal event pipeline
export const pipeline = createPipeline({
  eventTypes: 8,
  normalize:  'at-entry',
  retry: backoff({
    attempts: 3,
    strategy: 'exponential',
  }),
  dataLoss: 0,  // non-negotiable
});

Student Mobile App + Admin Platform

Sole developer · Android + iOS + Web admin

Cross-platform student app with multi-application tracking — each university application runs its own 8-stage timeline with update feeds and push-notification deep-linking
Admin panel with full CRUD and a clickable stage pipeline that auto-pushes updates to the student’s feed — every action audit-logged
Remote-config pattern: branding, stats and feature flags fetched on launch — live theme changes with no app-store release, managed via a phone-preview customizer
Single shared API serving both clients; server acts as a CRM proxy layer so API keys never reach the mobile client

remote-config.ts

// live UI changes, no app-store release
const config = await api.fetchConfig();

applyTheme(config.branding);
setFlags(config.features);

// CRM keys live server-side only
export const crm = proxy({
  exposeKeys: false,
});
