# SOMPOM > SOMPOM fixes, migrates, and builds critical business systems nobody wants to touch. > ERP migrations blocked, payment gateways broken, billing leaking revenue, > legacy systems with no documentation, vendors nobody can challenge. > We identify the real bottleneck and stay involved until operational control is restored. ## What we do - [What we fix](https://sompom.com/#positioning) — Revenue blocked, projects stuck before production, vendor dependency, unreliable data, systems breaking under load, full rewrites pushed without reason, inability to evolve the codebase, unclear product specifications, products that cannot be scaled or sold. - [Services](https://sompom.com/#services) — Recovery (Project Recovery, Legacy System Takeover, Vendor Replacement), Migration (System Migration, Data Migration & Integrity, Parallel Deployment), Build (System Integration, End-to-End System Delivery). - [What we build](https://sompom.com/#whatwebuild) — Web applications, mobile applications, marketplaces and e-commerce platforms, ERP and billing systems, real-time systems, case management systems, mobile game systems. - [AI Systems](https://sompom.com/#ai) — Document Processing & OCR, turning documents into searchable decisions, AI-driven task automation for variable and unstructured inputs, controlled deployment with data sovereignty. - [Selected Work](https://sompom.com/#use-cases) — Case management platform built from scratch, still running after ten years. Legacy takeover in a regulated audited environment, still maintained after six years. E-commerce rebuilt after ERP vendor shutdown, 100,000+ products migrated without transaction loss. SaaS transformation of an inherited codebase delivered in under four months without a full rewrite. - [Technical stack](https://sompom.com/#stack) — Full stack coverage from backend to mobile, AI, infrastructure, and game systems. ## Technical stack - Backend: Phoenix/Elixir for real-time and high-concurrency systems. PHP, Symfony, Python, C# for business applications, ERP integrations, and legacy environments. Payment integration: Stripe, bank gateways, crypto. - Frontend: Angular, Vue.js, Tailwind CSS. Operational interfaces, back-office systems, dashboards. - Databases: PostgreSQL, MySQL, MariaDB for transactional systems. MongoDB for document workloads. Elasticsearch, Manticore Search for full-text search and catalog indexing. - Infrastructure & Deployment: DigitalOcean, ScaleGrid, Bitbucket, GitLab CI/CD, Docker for development and build artefacts. Custom deployment scripts. We adapt to existing client infrastructure when required. - Mobile & Stores: iOS and Android since before Swift — Objective-C, Java, then Swift, Kotlin, Flutter. Full delivery including in-app purchases, subscription management, App Store Connect, Google Play Console. - AI Systems & Automation: LLM integrations with OpenAI, Anthropic, Hugging Face. Local model deployment for data-sensitive environments. Vector search, RAG pipelines, OCR, workflow automation. - Technical SEO: SEO architecture, crawl optimization, indexing strategy, URL structure — including migration scenarios where preserving search equity matters. - Game Development: Unity, iOS, Android. Ad mediation setup, waterfall and bidding configuration, virtual economy design, store compliance. ## Approach - Three intervention areas: recover blocked or abandoned systems, migrate operations without disrupting revenue, build critical systems from architecture to production. - Business-first: revenue protection, operational continuity, billing integrity, decision clarity. - AI is used when it solves a real problem — not as a default. Many problems presented as AI can be solved with structured databases, reliable search, and controlled workflows. - We stay through delivery: vendor challenge, implementation control, production rollout, and operational stabilization. ## Who we are - Independent practice based in Phnom Penh, Cambodia. - Senior engineering team, 10 to 15 people depending on active engagements. - Operating across Southeast Asia, Europe, North America, and Latin America. - Experience spanning mobile platforms before Swift existed, cloud infrastructure, and now AI systems. ## Contact - Website: https://sompom.com/ - Email: contact@sompom.com
