TrioAmigo is a team of three senior engineers and long-time colleagues, each with 8–10+ years of production experience, based in Belgrade (Serbia) and East Sarajevo (Bosnia and Herzegovina). We help founders and engineering leaders build new products, add AI to existing ones or strengthen in-house teams, mostly with .NET, React and AWS. Between us, we've shipped 50+ projects across web, cloud and enterprise software. What we build: full-stack web platforms and REST APIs (React, Next.js, Angular, TypeScript, .NET/C#, Node.js, Python); cloud-native and serverless systems on AWS (Lambda, SQS, S3, ECS Fargate, Step Functions) with Docker and CI/CD; applied AI with LLM features on Amazon Bedrock and RAG architecture; multi-tenant SaaS with OAuth2/OIDC; and modernization of legacy .NET Framework and Angular apps. Recent work: an enterprise inspection platform (~24 services, multi-tenant, large-scale imagery) used by a global energy company across its wind-turbine fleet, led by our architect for 6+ years; a gigapixel image pipeline rewritten from .NET to Python/libvips, benchmarked 16–20× faster on real inspection data; a serverless AI video translation and dubbing pipeline and a conversational no-code app builder on Amazon Bedrock, both in production at clients. Why a team instead of individual hires: a principal architect, a backend/cloud engineer and a full-stack engineer who already share standards and tooling. No recruiting, no long onboarding, no single point of failure, and one contract for the whole team. We prefer fixed-price milestones with a clear scope, with written design docs, a weekly demo and peer review on every pull request. Our CET/CEST hours give a full workday of overlap with the UK and EU and 2–3 hours with US Eastern. Tell us what you're building and we'll reply with an approach, milestones and an estimate.

Bitontree is an AI engineering company founded in 2019 in Ahmedabad, India. We build and run production AI systems for healthcare, logistics, legal, SaaS, e-commerce, recruitment, and real estate teams. Our delivery model is embedded rather than transactional. Senior AI engineers join your sprint cadence, work against your codebase and constraints, and stay involved after launch. That means monitoring live behaviour, maintaining evaluation suites that catch model drift, and tuning prompts and retrieval as real usage patterns emerge. Capabilities include AI agent development, RAG and knowledge systems, AI document processing, AI chatbot development, voice AI agents, AI workflow automation, and MCP server development, alongside AI strategy and proof-of-concept engagements for teams scoping their first system. We support HIPAA-aware delivery with business associate agreements, PHI-safe data pipelines, and SOC 2-aware security practices.
Metatech Official is a mobile app development company specializing in complete digital product solutions for startups, small and medium-sized businesses, entrepreneurs, and established organizations. Since 2018, we have helped businesses transform concepts into reliable, scalable, and intuitive mobile applications aligned with their operational objectives and customer requirements. Our mobile app development services span the complete product journey, including research, planning, UI/UX design, development, testing, deployment, maintenance, and ongoing improvements. Our expertise includes Android and iOS app development, cross-platform solutions, backend development, API integration, database architecture, cloud services, quality assurance, deployment, application optimization, and long-term technical support. Every project is approached according to its individual business and technical requirements rather than through a one-size-fits-all process. Before development begins, we consider factors such as the target market, business model, user journeys, integrations, technical requirements, scalability needs, and long-term product plans. This helps us build applications that address immediate requirements while providing a foundation for future growth. Our team has experience developing applications and digital platforms across numerous industries. These include ecommerce, marketplaces, food delivery, logistics, healthcare, fintech, trading, Web3, transportation, real estate, dating, fitness, education, IoT, augmented reality, hospitality, and other specialized business solutions. For ecommerce and marketplace applications, we develop functionality such as product listings, advanced search, filtering, customer accounts, shopping carts, checkout systems, payment gateways, order processing, vendor panels, inventory integration, push notifications, and administrative dashboards. We focus on creating straightforward shopping experiences while providing businesses with the tools required to manage their operations efficiently. For logistics and delivery businesses, we create interconnected platforms that support customers, merchants, drivers, dispatch teams, and administrators. Features can include live order tracking, dispatch management, shipment status updates, driver management, notifications, routing functionality, and operational dashboards. Connecting these roles within a unified platform helps streamline complex delivery processes. Our healthcare, fitness, and wellness solutions can include appointment booking, telemedicine platforms, patient portals, health and fitness tracking, reminders, progress monitoring, dashboards, and customized workflows. For fintech and trading products, we develop solutions around secure architectures, account management, backend systems, API integrations, structured user journeys, and transaction-oriented functionality according to project specifications. We also develop Web3 and blockchain applications, including cryptocurrency wallets, multi-chain wallets, token platforms, blockchain integrations, smart contract connections, decentralized application interfaces, and supporting backend infrastructure. Our approach is focused on presenting complex blockchain functionality through interfaces that remain understandable and accessible to everyday users. UI/UX plays an important role throughout our development process. Our designers create wireframes, user journeys, navigation structures, responsive interfaces, and consistent visual systems with usability in mind. The goal is to produce applications that look professional while allowing users to complete tasks efficiently across different screen sizes and devices. Our technical teams handle the underlying infrastructure required to operate modern applications, including backend development, APIs, databases, authentication, authorization, role-based permissions, third-party integrations, and administration systems. We emphasize organized and maintainable architecture so products can accommodate additional users, features, integrations, and changing business requirements over time. Quality assurance is incorporated into the development lifecycle rather than treated solely as a final step. Applications are evaluated for functionality, user flows, integrations, device compatibility, responsiveness, and performance before release. Following deployment, we can provide ongoing maintenance, issue resolution, updates, feature development, technical improvements, and performance optimization. Since establishing our services in 2018, Metatech Official has expanded its capabilities across mobile applications, custom software, web technologies, and emerging digital solutions. Our aim is to develop technology that delivers measurable practical value, whether a business wants to improve customer interaction, automate internal processes, introduce a new digital service, or build an entirely new product. Beyond mobile development, we also offer website development, web application development, UI/UX design, SEO, PPC management, and digital marketing services. This enables businesses to combine product development and digital growth initiatives through a single technology partner. Companies seeking experienced app developers can engage Metatech Official for projects ranging from startup MVPs and proof-of-concept applications to large-scale customer platforms and enterprise systems. As a mobile app development agency, we emphasize organized planning, transparent communication, appropriate technology selection, scalable architecture, and consistent execution throughout the development process. Whether the requirement involves custom app development, custom mobile app development, Android applications, iOS applications, backend infrastructure, API integrations, or complete digital product development, our team can assist from the initial concept through deployment and ongoing support. For organizations searching for mobile app development in Pakistan, Metatech Official delivers customized technology solutions based on business goals, user expectations, and long-term expansion plans. Our focus is on creating dependable digital products that are practical to manage, straightforward to use, and prepared to evolve alongside the business.
Dev Loader is a founder-led Laravel studio operated by Dev Loader, LLC, a US-registered company (est. 2021). We help founders and product teams rescue, upgrade, and finish Laravel SaaS applications — and build the React, Node, and mobile front ends around them when the product needs them. What we do: Laravel Application Rescue — Your previous developer disappeared, the codebase is undocumented, and deployment is fragile. We take over the repository, stabilize production, and deliver a written stabilization plan within the first sprint. Laravel Upgrade Service — We upgrade legacy Laravel applications (5.x through 11.x) to Laravel 12/13 and PHP 8.3+, including dependency audits, test-suite repair, and zero-downtime migration plans. Laravel SaaS Development — Narrow, well-scoped SaaS MVPs built on Laravel, Livewire, Filament, and Stripe billing. Audit $299 → rescue sprint $1,000 → feature build $2,500 → SaaS MVP from $6,000. Filament & Livewire Development — Custom admin panels, dashboards, and reactive interfaces on the TALL stack (Tailwind, Alpine, Livewire, Laravel). Performance Optimization — Query profiling, caching strategy, queue tuning, and Core Web Vitals improvements for Laravel applications under load. How we work: Fixed scope, fixed price — Every engagement starts with a written proposal. No surprise hourly invoices. Direct founder-engineer delivery — You work with the senior engineer who builds your project. No account managers, no rotating contractor bench. Full transparency — Repository access from day one, milestone-based delivery, and complete source code ownership at handoff. No hosting lock-in. Who we work best with: Technical founders, small product teams, and agencies running Laravel applications — especially SaaS products that are 80% built and stalled, running outdated Laravel versions, or suffering from performance problems under growth. We deliver remotely worldwide from our registered office in Washington, DC, with replies within one business day.
