A connected system. ![Portrait of Tameem Ahmad Shahzad](https://www.hubdevpro.com/hubfs/raw_assets/public/hubdevpro/images/profile.png) [TOP RATED PLUS](https://www.upwork.com/freelancers/~011467e34f815ba25b) **TAMEEM AHMAD SHAHZAD**ID // HS-DEV-01 I help businesses turn HubSpot into a fully connected operating system. Across **45+ projects**, I've connected HubSpot to the payment, authentication, booking, ERP and enterprise CRM platforms businesses actually run on: **Stripe, PayPal, Apple Pay, Auth0, Chargify, Mindbody, EXO, Ostendo, Snowflake, Salesforce, Dynamics 365, Business Central, NetSuite**, and other systems where native apps fall short. Using **Laravel** as the backend foundation, I build hybrid architectures pairing HubSpot CRM + CMS with external systems – production systems built to survive retries, rate limits, and real-world data consistency issues. 0 Projects shipped on Upwork 0 Years in production engineering 0 Platforms connected end-to-end 0 Production, zero demos 02 · Capabilities ## Systems I build CAP // 01 ### Payment & subscription sync Stripe, PayPal and Chargify billing state mirrored into HubSpot deals and custom objects – invoices, dunning, upgrades and churn kept in sync as they happen. StripePayPalChargifyCustom Objects SYNC: BI-DIRECTIONAL · MODE: REAL-TIME CAP // 02 ### Identity & auth bridges Auth0-backed login tied directly to HubSpot contact records, so account state, roles and permissions stay consistent between your app and your CRM. Auth0SSOWebhooks SYNC: EVENT-DRIVEN · MODE: ASYNC CAP // 03 ### Booking & scheduling engines Mindbody-style booking and session data synced with HubSpot timelines and workflows, so sales and support see the full customer journey in one place. MindbodyWorkflowsTimeline Events SYNC: BI-DIRECTIONAL · MODE: REAL-TIME CAP // 04 ### Reliability layer The plumbing that keeps every sync correct under real traffic: retries with backoff, idempotency keys, webhook signature validation and rate-limit management. RetriesIdempotencyRate Limits FAILURE MODE: GRACEFUL · RECOVERY: AUTOMATIC 03 · Portfolio ## Selected builds Featured 01 ### Recurring billing bridge Problem Stripe/Chargify subscription state lived in one system, deal stage and revenue reporting lived in another – sales had no live view of billing health. Solution Laravel webhook layer mirrors invoices, upgrades and churn into HubSpot deals and custom objects in real time, with retry queues for failed syncs. Stack Stripe · Chargify · Laravel queues · HubSpot custom objects WebhooksIdempotencyCustom Objects 02 ### Identity-aware CRM Problem Auth0 handled login and roles, but HubSpot contact records didn't know who was actually signed in or what tier they were on. Solution Event-driven sync keeps contact lifecycle stage, role and account status aligned between Auth0 and HubSpot the moment identity changes. Stack Auth0 · Laravel · HubSpot workflows · signature-verified webhooks SSOLifecycle StagesWebhook Security 03 ### Booking-to-revenue pipeline Problem Mindbody bookings and session history were invisible to sales and support inside HubSpot, so follow-ups happened blind. Solution Bi-directional sync writes bookings as HubSpot timeline events and triggers workflows for no-shows, renewals and upsell windows. Stack Mindbody · Laravel · HubSpot timeline events & workflows Bi-directional SyncTimeline EventsAutomation More builds Real Estate #### Listing & property sync Property CRM listings mirrored into HubSpot as searchable, stage-tracked deal records. Commercial Property #### Unit-level deal pipeline Custom objects modeling buildings, units and leases so commercial deals track at the right granularity. Zapier #### No-code ops automation Lightweight Zapier flows for teams that need a fast bridge without a full custom integration. n8n #### Self-hosted workflow orchestration Multi-step n8n flows for logic too complex or too sensitive for a no-code SaaS tool. UI Extensions #### Custom CRM cards for reps HubSpot UI extensions surfacing external billing and booking data right inside the contact record. Serverless #### Serverless middleware functions HubSpot serverless functions handling auth and light transforms between CRM and external APIs. Security #### Webhook signature framework A reusable verification layer so every inbound webhook is authenticated before it touches data. Multi-Tenant #### Multi-portal billing sync Subscription lifecycle kept consistent across several HubSpot portals sharing one billing backend. Data Hygiene #### Contact dedupe engine Workflow-driven matching and merge rules that keep the CRM's contact base clean at scale. Reporting #### Revenue attribution feed External revenue and usage data piped into HubSpot so reporting reflects the whole funnel. Rate Limits #### Bulk backfill engine Chunked, rate-limit-aware batch sync for safely backfilling years of historical records. Migration #### Legacy CRM migration toolkit Field-mapped, validated migration of records and history from a legacy CRM into HubSpot custom objects. Custom Code #### Custom-coded workflow actions Server-side code actions inside HubSpot workflows for logic no native action can express – scoring, routing, external lookups. CMS Modules #### Custom drag-and-drop CMS modules Reusable, field-driven modules built for HubSpot CMS so marketing can compose pages without touching code. Marketplace Apps #### Third-party CRM extensions HubSpot Marketplace-style app connections that plug external platforms in as first-class citizens, not bolted-on scripts. #### [Legal / Real Estate Time-boxed case assignment Zillow, CREXi and LoopNet leads parsed by Zapier, auto-assigned to lawyers with an accept/decline timer, then handed to PandaDoc.](https://www.hubdevpro.com/case-studies#lawfirm) 04 · AI Agents ## Built for the agent era AI AGENT MCP SERVER HUBSPOT #### MCP tool servers HubSpot objects, workflows and timelines exposed as typed, permissioned tools an agent can call – not a raw API surface it has to guess at. #### Guarded write access Every agent-triggered write runs through the same validation, idempotency and audit trail as a human-triggered one. No silent side effects. #### Structured context, not dumps Deals, tickets and contact history shaped into the context an agent actually needs, so answers stay grounded instead of hallucinated. hubspot\_mcp\_tool.ts ``` server.registerTool("get_deal_summary", { description: "Read-only summary of a HubSpot deal for agent context", inputSchema: { dealId: z.string() }, async handler({ dealId }) { // scoped token, read-only – the agent never touches raw creds const deal = await hubspot.deals.get(dealId, { readOnly: true }); return { stage: deal.stage, amount: deal.amount, lastActivity: deal.timeline.latest() }; } }); ``` 05 · Under the hood ## How a sync actually survives production webhook\_handler.php ``` class StripeWebhookHandler { public function handle(Request $req) { // 1. verify the signature before trusting anything if (!Signature::verify($req, config('stripe.secret'))) abort(400); // 2. de-dupe on Stripe's event id (idempotency) if (ProcessedEvent::seen($req->event_id)) return response()->noContent(); // 3. queue it – HubSpot's API waits for no one SyncToHubspot::dispatch($req->payload) ->onQueue('hubspot-sync') ->backoff([5, 30, 120, 600]); return response()->noContent(); } } ``` bulk\_backfill.js ``` async function backfillContacts(records) { const chunks = chunk(records, 100); for (const batch of chunks) { const res = await hubspot.batchUpsert(batch); // respect HubSpot's rate limit headers, not a guess const wait = retryAfter(res.headers) ?? 150; await sleep(wait); if (res.status === 429) { await sleep(wait * 4); chunks.unshift(batch); // retry this batch } } } ``` hs\_workflow\_action.php ``` class ScoreLeadAction { // custom-coded action, called by a HubSpot workflow public function execute(array $context): array { $contact = $context['object']; $score = Scoring::calculate( $contact['company_size'], $contact['engagement_events'] ); return [ 'outputFields' => ['lead_score' => $score] ]; } } ``` 06 · Process ## How an engagement runs 01 #### Discover Map the systems you already run on and where HubSpot's native tools stop being enough. 02 #### Architect Design the data flow: what's the source of truth, what syncs where, and how failures get handled. 03 #### Build Ship the HubSpot side (objects, workflows, UI extensions) and the Laravel backend together. 04 #### Harden Add retries, idempotency, signature checks and monitoring so it survives real traffic, not just demos. 05 #### Ship Deploy, document, and hand over a system your team can actually maintain. 07 · Stack ## Skills & tools ### HubSpot - CRM & CMS architecture - Custom objects & workflows - UI extensions - Serverless functions ### Integrations - REST API design - Webhook architecture - Zapier & n8n - Bi-directional data sync ### Backend - Laravel - Stripe / PayPal - Auth0 - Rate limits & retries 08 · Career ## Experience Senior Software Engineer JUL 2021 → PRESENT · 5Y 2M Computan - Architected and shipped 30+ custom HubSpot integrations across diverse client stacks, owning each from requirements to production deployment - Connected HubSpot to Stripe, PayPal, Auth0, Chargify, Mindbody, and other SaaS platforms where native apps fall short - Built Laravel-based backend services for API integrations, webhook handling, and bi-directional data syncs (real-time and async) - Engineered sync reliability: retries, error handling, rate-limit management, data-consistency safeguards - Developed custom HubSpot workflows and custom objects spanning payment, subscription, authentication, and booking lifecycles - Applied security best practices: token management, webhook signature validation, environment isolation - Created reusable integration patterns that reduced delivery time across multiple client projects - Acted as technical point of contact for complex HubSpot and integration challenges Laravel Developer DEC 2020 → JUL 2021 · 8M TechSwivel (Private) Limited Lahore District, Punjab, Pakistan Laravel Developer APR 2018 → JAN 2020 · 1Y 10M Skp Software Technologies Lahore, Pakistan 09 · Education ## Education ### BSCS, Computer Engineering The Islamia University of Bahawalpur · 2014 – 2018 10 · Certifications ## Certifications AI Fluency for Small Businesses AI Fluency for Nonprofits AI Fluency for Students AI Fluency for Educators AI Capabilities and Limitations 11 · Contact ## Let's connect your stack.
