Vestlite is an international product studio building technically complex digital products for B2B clients — AI agents and document intelligence, web platforms and marketplaces, GPU pipelines, browser automation, blockchain, mobile, end-to-end automation. From architecture and design to release and support.
Vestlite is a product studio founded in 2018. We design and build custom digital products for businesses — from MVP to scale-stage systems with hundreds of thousands of users.
We are not a freelance marketplace and we are not an outsourcing factory. Eight in-house specialists — five engineers, one QA, two on sales — together since 2018, 10+ yrs each individually. Predictable staffing, no "moved to another project" surprises.
Most of our work is direct B2B contracts. A small share is white-label contractor work for agencies that need senior engineering capacity under NDA.
No bench, no juniors disguised as mids. Five engineers, all Senior+, shipping technically complex systems together since 2018 — 10+ yrs of experience each individually.
Architecture, frontend, backend, mobile, infra, QA — all in one team. No multi-vendor coordination tax.
Every case in this document is in production with paying users. We ship, monitor, and support post-release.
Document processing pipelines: any format in, structured data out. Invoice extraction, stamp validation, human-in-the-loop review. CV models, LLMs, vLLM serving, GGUF quantization for cost control.
Outcomes: hours of manual review → minutes · multi-format ingest (XLS/DOCX/JPG/PDF) · confidence-gated routing
Custom platforms from MVP to hundreds of thousands of users. SaaS, dashboards, B2B portals, headless commerce, multilingual catalogs with 500K+ SKUs.
Outcomes: 700K-user products held through architecture redesigns · 10× throughput on critical paths · daily release cadence
GPU pipelines on spot pricing, browser farms with anti-detection at the C++ level, blockchain event ingestion at 500 evt/s. Self-managing — provisions, runs, tears down idle.
Outcomes: enterprise-grade GPU jobs at spot prices · scale-to-zero idle · reliable extraction where Playwright gets blocked
iOS, Android, cross-platform. Fintech, retail, logistics. Store releases, analytics, biometry, payments.
Outcomes: store-ready releases · biometry & payments integrations · KYC pipelines
Process automation, orchestration, monitoring, alerting. Spec → production with a senior team: together since 2018, 10+ yrs each individually.
Outcomes: production observability from day 1 · stateful graph orchestration · explicit failure recovery
Listing aggregator across 18+ marketplaces (Vestiaire, Farfetch, eBay, Rebag, Fashionphile…). Local LLM extracts brand/model/condition/price from raw listings; outlier detection (≥3σ), histograms, per-source archives.
Multi-format ingestion (XLS, DOCX, JPG, PDF), custom CV models for stamp validation, structured extraction with Mistral on vLLM. GGUF quantization for cost. Hours of manual work → minutes of review.
Self-managing pipeline on vast.ai. Provisions GPUs on demand, runs multi-stage jobs (watermark / generation / face-enhance / upscale), tears down idle. SGLang + Cache-DiT on H100s. Spot-instance pricing.
Containerized browser farm with anti-detection at the C++ level. Camoufox + custom Go MITM proxy + Bézier cursor pathing. Reliable on sites that block standard Playwright/Puppeteer.
Engineering slice: Solidity smart contracts (TRON live, ETH L2 ready), CI/CD dev sandbox with local ETH+TRON nodes per-PR, seamless Directus → Strapi migration without downtime, tokenomics system architecture.
Architecture redesign at 700K users. Django monolith → service-oriented. Identified ORM hot paths, rewrote with raw query optimization. Release cadence weekly → daily, no downtime windows.
