À propos de Wassim

You have a product idea, a technical problem, or a team that needs to move faster. I cover the full chain — alone if needed.

From product scoping and Figma design to backend, AI pipeline, database architecture, DevOps, CI/CD, and production deployment: I own every layer. I've done it before. At Terracall, I built a full telecom-grade AI product from scratch with 3 engineers — Asterisk PBX, SIP/SMPP stack, real-time voice AI pipeline achieving 1.5s end-to-end latency (ASR + LLM + TTS + VAD), a generic CRM integration engine covering 10+ platforms, MongoDB clusters, Redis job queues with BullMQ, and full IaC with Pulumi.


Before that, 5 years at Zaion — France's leading conversational AI company — where I grew from end-of-study intern to Head of Engineering, then Head of Product, then CODIR (executive committee). I built the engineering team from 1 to 8 engineers + 2 DevOps: full hiring process (JDs, sourcing, technical interviews, salary negotiation, yearly reviews), engineering culture from scratch (code review standards, security reviews, dev lifecycle, OKRs for C-level), and managed through real crises — including a full infra provider outage recovered in 24h under client and internal pressure. Products I shipped are now deployed at 50+ French enterprise clients: Carglass, Edenred, La Banque Postale.

What I bring to your mission:
→ Full product ownership: from idea and scoping to commercial product — no handoffs
→ Technical breadth: AI pipelines, telephony, full-stack, databases, DevOps, integrations
→ Speed under constraint: I've shipped production systems in startup conditions, repeatedly
→ Management depth: I can lead, hire, and structure a team while staying hands-on in the code

Ideal missions:
— AI Product from scratch
— Full product build: idea → scoped → beta testers → production
— Technical architecture audit and roadmap
— Engineering team setup and scaling (early-stage startups)

Based in France. Remote-first. Available now.

  • Terracall
    CTO & Cofounder | AI Telecom Product
    TÉLÉCOMMUNICATIONS
    mai 2025 - Aujourd'hui (1 an et 1 mois)
    Paris, France
    Built a production-grade AI telecom product from zero with a 3-engineer team — owning every technical and operational layer.

    ▸ Telephony: Asterisk PBX, Dialplan (written personally), SIP stack, SMPP gateway, WebSocket real-time call handling, IVR, MNO/MNE API integration (pricing, roaming config)
    ▸ Voice AI pipeline: achieved 1.5s end-to-end latency (real-time ASR + LLM + TTS + VAD) — designed, built and tuned end-to-end
    ▸ Async call analysis pipeline: post-call data extraction, automatic email generation, CRM auto-fill, task automation for sales and SDR teams
    ▸ CRM engine: generic OAuth 2.0 integration framework covering 10+ platforms (Salesforce, HubSpot, Dynamics…) — new connectors added without standalone dev per platform
    ▸ Databases: MongoDB cluster management, replica sets, schema design, aggregation pipelines, indexing optimisation; Redis + BullMQ for async job queues, API caching, session management, rate limiting
    ▸ DevOps: CI/CD pipelines (GitHub Actions), IaC with Pulumi, Kubernetes on Scaleway, zero-downtime deployments, monitoring & alerting
    ▸ Design → Prod: Figma UI → Next.js frontend → NestJS backend → infra → automated deployment
    ▸ Support: HubSpot ticketing + live chat, AI assistant integration with custom knowledge base — full client onboarding and success management
    ▸ Pre-sales: technical demos, solution scoping, proposal support, and client negotiations alongside the sales team

    Results:
    → €4K MRR with zero dedicated sales staff — entirely founder-led
    → Infra costs controlled via startup credit programmes (Google, Microsoft, MongoDB Atlas, Scaleway) + dynamic ASR/LLM routing by task complexity

    TÉLÉCOMMUNICATIONS
    décembre 2023 - mai 2025 (1 an et 5 mois)
    Île-de-France, France
    PLUG & TEL is the parent company behind Terracall. As Head of Product Development, I led the full incubation of Terracall — from raw idea to a spun-out, commercially operating company.

    ▸ Product inception: defined the product vision, market positioning, and initial technical architecture from scratch
    ▸ Business foundation: built the business plan, prepared funding applications, and aligned the technical roadmap with strategic and financial goals
    ▸ MVP execution: led the full development cycle from concept to MVP — specs, roadmap, delivery
    ▸ Team creation: recruited and structured both the product and engineering departments from zero — defined roles, organised squads by scope and skillset
    ▸ Agile setup: implemented agile delivery processes and sprint cadences to keep a small team shipping fast
    ▸ Tech & innovation: led strategic technology watch and defined infrastructure and software architecture standards
    ▸ Spin-out: successfully transitioned Terracall from an internal incubation project into an independent entity with its own product, team, and commercial traction

    Results:
    → 0 → operational AI telecom product in under 18 months
    → Secured early traction and validated market demand before spin-out
    → Built the team and processes that allowed Terracall to operate independently

    GRANDE DISTRIBUTION
    octobre 2019 - novembre 2023 (4 ans et 1 mois)
    Paris, France
    5-year journey from end-of-study intern to executive committee — absorbing a new scope at every step.

    Engineering leadership:
    ▸ Built team from 1 → 8 engineers + 2 DevOps — full hiring cycle (JDs, LinkedIn sourcing, technical interviews, offers, salary reviews, bonuses)
    ▸ Managed scope conflicts between engineers, handled a redundancy under financial constraint (evaluation, selection, documentation)
    ▸ Absorbed PM/PO team mid-flight after manager departure — led both engineering and product simultaneously
    ▸ Built engineering culture from scratch: dev lifecycle, code review standards, security reviews, OKRs for C-level
    ▸ AWS migration: on-premise → cloud, –40% infra cost via right-sizing and auto-scaling
    ▸ Deployed self-hosted ASR to replace external provider — significant recurring cost savings
    ▸ Incident management: full infra provider outage recovered in 24h under client and internal pressure (PCA)

    Product leadership:
    ▸ Launched Zaion Analytics, Zaion Assistant, Zaion Voice Analytics — deployed at 50+ French enterprise clients: Carglass, Edenred, La Banque Postale
    ▸ Voice Analytics opened a net-new revenue stream for the company
